Authentication Failure Issue; Network Management Card (NMC) Based Products

Authentication Failure Issue; UPS Network Management Card (NMC) Based Products
Mr. Todd Bertolozzi, CCNA and Mr. Christopher Walter, CISA, GCIH, notified APC of a high risk security vulnerability that affects APC UPS Network Management Card (NMC) based devices. Following is a description of this issue and actions underway by APC to mitigate and correct the issue. This report is a result of an effort by a security analyst to determine vulnerabilities with APC products.


As reported, the UPS NMC is vulnerable to a web user interface authentication failure attack.

Product Line
  • Network Management Card 1 (NMC1) - AP9617, AP9618, AP9619
Devices with an embedded Network Management Card 1 include (but are not limited to): Metered/Switched Rack PDUs (AP78XX, AP79XX), Rack Automatic Transfer Switches (AP77XX, Environmental Monitoring Units (AP9320, AP9340, Netbotz 200)
  • Network Management Card 2 (NMC2) - AP9630/AP9630CH, AP9631/AP9631CH, AP9635/AP9635CH
Devices with an embedded Network Management Card 2 include (but are not limited to): 2G Metered/Switched Rack PDUs (AP86XX, AP88XX, AP89XX), Certain Audio/Video Network Management Enabled products.

  • AP9630/31 NMC2 based devices running the following applications:
    • Smart-UPS v5.1.0 (SFSUMX510)
    • Symmetra v5.1.0 (SFSY510)
    • Symmetra 3 Phase v5.1.0 (SFSY3P510)
  • AP9617/18/19 NMC1 based devices running the following applications:
    • Smart-UPS v3.7.1 (SFSUMX371)
    • Symmetra v3.7.1 (SFSY371)
    • xPDU v3.7.1 (SFXPDU371)
    • Symmetra 3 Phase v3.7.1 (SFSY3371)
    • Silcon v3.7.1 (SFDPE3E371)

During the investigation of the reported matter, the reported and actual issue was found to be identical. While the reported issue was specific to the Smart-UPS device, this issue exists across recently released versions of UPS NMC based applications.
APC has released a firmware revision to address this issue, available for immediate download here.

If you choose not to utilize the above solution, the following mitigation strategies can be employed to reduce or eliminate the potential for this issue to manifest.
  • As this authentication failure bases itself in use of a URL in web applications, disabling the web interface on the UPS NMC will eliminate the possibility of such vulnerability from occurring. Other interface methods such as Telnet, SNMP, and serial connections are unaffected by this issue. Note the web interface can be disabled via the config.ini or via any other interface. See the UPS NMC documentation for detailed instructions.
  • Placement of the UPS NMC on a private or secure network (e.g. behind a firewall) will prevent external unauthorized users from a accessing the UPS NMC.
  • Changing the default ports used by the UPS NMC for transacting web based information (e.g. port 80 for HTTP, and port 443 for HTTPS) to a non-standard port will mask the issue.
  • APC recommends implementing industry standards including administrator access to computers and the operation of security scanners.
APC Actions:

As APC is concerned about any potential vulnerability no matter how narrow, we are undertaking the following steps to contain and correct this issue:
  • APC has removed the effected firmware versions from the appropriate download locations.
  • APC has made a complete report of this finding to the individual responsible for finding the vulnerability.
  • APC has implemented a firmware fix for the detailed issue for each relevant application. They are readily available to the general public via our web site (
  • APC will send out an email notification to those customers who have signed up to receive APC's Software & Firmware release update newsletters.


SPM 7.0 / 7.0.1 - Installer fails at step CheckAppModsDatabase

During a 7.0.1 install or upgrade, the installer fails at step CheckAppModsDatabase. It will be considered an incomplete install.
Re-trying does not resolve the issue.
In the Setup log, there will be a long stack trace resembling one of the ones listed in the Causes section below.

Struxureware Power Monitoring Expert 7.0


Cause 1
The Windows account that SQL Server service is running as, does not have file/folder access to the location stated in the error. It's trying to execute a bulk load from file Unit.xml but fails. This is usually because service has been run under non-standard account. (i.e. something other than LOCAL SYSTEM, which is usually the default.)

Installer log will indicate an error was found in ApplicationModules.log file. Navigate to the log file as listed in the error message and open it. Error will resemble:

    • Starting Synchronization of [CommonDataModel].[Unit]
      Msg 4861, Level 16, State 1, Server STANDALONE\ION, Line 4
      Cannot bulk load because the file "C:\Users\Administrator\Desktop\SPM 7.0.1\setup\SetupSupport\Database\ReferenceData\CommonDataModel\Standard\Unit.xml" could not be opened. Operating system error code 5(Access is denied.).
Resolution 1
a) temporarily grant read/write permissions to the folder listed in the error, to the user account SQL Server is running under.
b) change SQL Server to run under the LOCAL SYSTEM account.
Then re-try running the installer to complete.

Cause 2
ApplicationModules database files (.mdf and .ldf) have already been created at the target location, but are not attached to SQL Server. The installer tries to re-create the files but fails. This situation can occur when trying to re-configure multiple times (for instance, after encountering the situation described in Cause 1).

Installer fails with message "The ApplicationModules database could not be found." Installer log contains the following error:
    • executeNonQuery(CREATE DATABASE ApplicationModules ON ( FILENAME = 'C:\Program Files\Microsoft SQL Server\MSSQL10_50.ION\MSSQL\DATA\ApplicationModules.mdf'), ( FILENAME = 'C:\Program Files\Microsoft SQL Server\MSSQL10_50.ION\MSSQL\DATA\ApplicationModules_log.ldf') FOR ATTACH, master) Failed on exception:

      Msg 1802, Level 16, State 4, Server STANDALONE\ION, Line 1
      CREATE DATABASE failed. Some file names listed could not be created. Check related errors.

Resolution 2
Delete or rename the existing ApplicationModules database files, the re-run the installer. Let the installer re-create the database and complete the install.

Cause 3

The installer fails to create the application modules database successfully.

Resolution 3

Checking the diagnostics within the C:\Program Files (x86)\Schneider Electric\ION Enterprise\Applications\Diagnostic shows the following error message: "CREATE DATABASE failed. Primary file must be at least XX MB to accommodate a copy of the model database."

Instead of "XX" an actual file size will be given. In this situation SQL is attempting to create the Application Modules database, but the Model database is larger in size. All newly created SQL databases must be larger in size than the model system database to succeed. Within SQL Management Studio backup and perform a shrink operation on the model database which should allow the installer to succeed creating the Application Modules database. Right click on the model Database -> tasks -> shrink.

Trio Radio Installation - Grounding Antennas, Towers and Cabinets.

There's a general lack of understanding of how to provide lightning protection for radios, antennas and towers. Many installers either ignore the issue, do the minimum possible, or sometimes even cause significant problems with their installation. Below is a brief discussion of common issues.

1) Typically the antenna itself does not need to be grounded by the installer. The antenna is mounted with a metal clamp on a metal pole, which must be grounded.


2) If the antenna is a yagi, (directional type) it's a good idea to mount the antenna several feet below the top of the mast (spacing at least equal to antenna's length) to allow the mast to take the main hit on a lightning strike.

3) If the antenna is an omnidirectional type it's often mounted at the very top, though some are mounted on arms 2-3 feet out on the side of a tower. Many of these types are "DC grounded" which means the radiating element goes thru a coil to ground, allowing static buildup to be bled off as it tries to develop. This is often sufficient, but in some very heavy lightning areas installers may run a lightning rod around the omni and a few feet above. It must be kept well away from the antenna (a couple of feet) so it's a bit awkward but hardware does exist.

4) If the tower is tall a cable grounding clamp should be installed every (approx) 75 feet which grounds the coax outer shield to the tower itself. This bares the outer shield (braid) so care must be taken to waterproof the cable/clamp afterwards.

5) A good quality surge arrestor (eg polyphaser) must be used at the building entrance. It may be mounted in a metal feed-through plate, may be a simple in-line type, but must be connected to a heavy gauge ground cable or strap.

6) The ground cable from the surge arrestor must be heavy green ground cable, kept as short and straight as possible with NO coils and no sharp bends. These add inductance, which acts as a resistance to the high frequency energy of a lightning strike.


7) Ground cables must not run through metal conduit. This adds impedance and can pick up noise.

8) Be aware that surge arrestors will fail after a period of time, either from absorbing one big surge or multiple smaller surges. This may appear as either an open circuit or more commonly as a source of high VSWR. (reflected power) Keep a spare handy and try swapping out the unit at site if high VSWR is seen.

9) A surge arrestor is not truly a lightning arrestor. A direct hit to the antenna may send enough energy through the system that the arrestor is overwhelmed, causing serious damage to the radio and attached equipment. A surge arrestor is primarily aimed at bleeding off the buildup of static charge to prevent a lightning strike in the first place.

10) The ground cable must go to an industrial quality ground rod or plate, installed according to local regulations or better. This must be an 8 or 10 foot rod.

11) All grounds should go to a common point eg a metal plate at the building cable entry point. Daisy-chained ground connections must be avoided.

12) The mast (if short eg 10-20 ft) must be grounded at the bottom with a short straight cable to a ground rod. Preferably a separate one but at a site where a short mast and the cabinet are close together often one rod is used.

13) If a small antenna structure is used a single long ground rod may be used at its base, but for a normal tower a ground ring should be installed with 3 or more ground rods, a ring of heavy copper wire connecting them, and several cables running out from the tower.


The above comments are general in nature. Several very good websites exist with far more information about grounding procedures and hardware. A quick Google search should find plenty of good reading.


Equipment connected to a Back-UPS product turns off unexpectedly and/or reboots.


There are many possible scenarios in which a Back-UPS product might drop or reboot the attached equipment. Below are potential problems ordered by commonness.

Product Line:

All APC Back-UPS and Conext related products.



Cause / Resolution:

Problem #1: Equipment connected to the wrong outlets
Investigation: Follow the input power cord of the equipment that shut off back to the outlet that it is plugged into on the Back-UPS product, if the outlet’s label does not have the words “battery backup” this is why it has dropped the load.
Solution: Not all the outlets on a Back-UPS product provide backup power in the case of a power disturbance. Unplug the equipment and make sure your vital equipment gets plugged into the outlets labeled Battery Backup. Any thing that does not require backup power should be plugged into the surge protection only outlets.

Problem #2: Capacity overload
Investigation: In the technical specification section of the user’s manual that came with the Back-UPS product there is a watt rating listed. That is the maximum wattage that can be attached to the Battery Backup outlets and still have a decent runtime in the event of a power problem. If there is too much attached it will not be able to be supported by the battery. Make a list of all the equipment that is being plugged into the Back-UPS product.
Solution: Determine what equipment would be required to stay on in the event power failed for an extended period of time. These are the things that will need to be plugged into the battery backup outlets. The rest should be plugged into the surge only outlets that do not provide battery backup. If the total Wattage of the equipment that is being plugged into the battery outlets is more than the wattage of the battery outlets then the Back-UPS product will NOT be able to support that equipment in the case of a power disturbance.
You can confirm at if your Back-ups product is to small or not.


Problem #3:The Circuit Breaker tripped:
Investigation: Check the circuit breaker located on the rear of the UPS or near the input cord. The circuit breaker is labeled ""Press to Reset"". The circuit breaker will ""trip"" or pop out if there is a severe overload on the output side of the UPS (i.e., too much equipment is plugged into the UPS).
Solution: Reducing the load, then press the ""Reset"" button in. If the circuit breaker is tripped if it protrudes approximately 1/4"" out from the unit. Once pushed back in, try to power the unit up again. If breaker will NOT stay in, contact APC at Technical Support and have the Model and serial number available.

Problem #4: The UPS exhausted its available battery power
Investigation: Back-UPS products can only supply battery power for a limited time before the unit must shutdown to protect itself from totally discharging. In some cases, depending on the size of the load and the size of the Back-UPS product's batteries, it may only have a few minutes of battery power. Try to determine if the UPS had been on battery shortly before the attached equipment has shutdown. Keep in mind that while normal power may seem to exist, many power problems are transparent or invisible to a user. These unforeseen power problems, such as voltage wave shape distortion, Harmonic Distortion, and frequency variances, will cause the UPS to go to battery. You may have found that your UPS has been going to battery but only for a very short amount of time. So, what may be happening is that it is going to battery frequently enough that the unit has not had enough time to recharge. Eventually, then, the UPS will shutdown (and drops all attached equipment).
Solution: This would not happen if the software that the Back-UPS product shipped with was installed. It can be configured to Gracefully perform and unattended shutdown. Then when power returned to acceptable it would return power to its outlets and if the equipment is configured properly it should reboot. If this happens often without there being a black out condition then most Back-UPS products can be Desensitized via either the front switch (If this is possible the instructions will be stated in the Back-UPS product’s user manual) And/or through the APC management software that the Back-UPS product shipped with. An example of the management software is PowerChute Personal Edition.

Problem #5: Connected equipment does not accept a stepped-approximated sine wave.
Investigation: This would be the case if only one of the pieces of equipment plugged into the battery backup outlets dropped while the other equipment in the battery backup outlets stay on when the unit transferred o battery power.
Solution: Back-UPS products output a step approximation of a sine wave when the unit is On Battery. While this kind of waveform is ideal for computers and computer-related equipment, it may not be compatible for other types of loads like motor loads. If you are using non-computer loads with one of the above mentioned UPS's, consult the manufacturer's specifications to determine if the equipment can run off of a ""stepped wave"". If it can't, then it will require a UPS which outputs a pure sine wave when On Battery. APC UPS single phase models which do output a Pure Sine Wave include: Smart-UPS >700VA, Matrix-UPS, and the Symmetra LX.

Problem #6: The power supply in your equipment is faulty and incapable of handling the transfer time of the Back-UPS product
Investigation: This would be the case if only one of the pieces of equipment plugged into the battery backup outlets rebooted while the other equipment in the battery backup outlets stay on when the unit transferred o battery power.
Solution: Depending on the model of the UPS, the transfer time (time it takes for the unit to transfer from On Line to On Battery) can vary anywhere from 2 milliseconds to 8 milliseconds. Modern computer and computer-related power supplies can ""ride through"" power outages as long as 10-20 milliseconds. Many, in fact, can last through a 50 millisecond gap in power. If the equipment is rebooting when the Back-UPS product transfers to On Battery operation, this may be the problem. Try to recreate the problem by connecting another device, pull the plug on the UPS (puts it on battery) to see if the new device stays up and running when the UPS goes to Battery. If it does, then its more likely that there is a problem with the power supply of the original piece of equipment. The manufacturer of the equipment will need to be inquired upon for further support in this situation.

Problem #7: Communication cable is attached but no APC management software is installed.
Investigation: On most Back-UPS products there is either a Data port, Serial port or USB port available for communication with a computer. The software is optional not mandatory. Check the Back-UPS product and see if there is anything attached to this port. If there is and there is no sign of APC management software installed on the computer there is a slight chance that the Back-UPS product might turn off for no apparent reason.
Solution: Either remove the cable and do not installed the software since its optional not mandatory, or leave the cable attached and properly install the software according to the instructions in the Back-UPS product’s user’s manual.

Problem #8: The UPS may be faulty
