Summary of security related changes for November 2021.

​Security Enhancement Summary:
K5_P6 Update – 5-Nov-2021:
 
NOTE: For use with “LX-800” CPU (C3414) ONLY. Will not work with 5X86 (C3413) or 486 and disk on chip configuration (C3412).
Operating System
Must update OPERATING SYSTEM to use this update!
 
NOTE: Due to California 2020 cyber-security regulations, users must immediately change the user access account from the default using the Sage User Manager tool. The user account file named “Schneider_Electric_1_USERS.tar.gz” located in the “FW_Update/Secure/updateGen” directory, only has up/download permission to enforce this policy, is delivered on new RTUs and installed when using the Initial Installer to convert a G3_P6 or earlier revision. The user account file named “Schneider_Electric_2.tar.gz”, located in the same path, has the old default “Admin” credentials. Use this user account file at your own risk.

Fixes:
þ Command Log: Fix issue with large number of old command log files causing CPU performance to degrade on startup as command log filenames get cataloged and listed into download menu. Very disk intensive process caused slowdown in GUI performance and configuration downloads. New limit imposed on number of command log files 744 files - 31 days of command log files created once per hour (24 * 31) - is enforced at startup. NOTE: Download any unsaved Command Log files prior to this update. Automatic enforcement of new limitation on number of files may cause unsaved Command Log files to be deleted at startup.

​Security Enhancement Summary:
Firmware C3414-500-S02K5_P5 released with these enhancements:
GUI: Configuration – CPU: Additional network service checkbox provided to allow customer to enable the ISaGRAF ETCP task, which will open listening ports to connect with ISaGRAF workbench.

Configuration – CPU: Non-secure networking services Telnet and FTP are disabled by default. Customer must enable them to use them and therefore assumes risk of using them.

Security Fix Summary:
Firmware C3414-500-S02K5_P5 released to fix:
VxWorks: Vulnerability CVE-2020-28895 malloc/calloc fix. Applied Wind River patch to bring code libraries current to 6.9.4.12 RCPL3 revision. This corrects issues with overflow causing malloc/calloc to return valid pointer when it should return fail indication NULL pointer.

VxWorks: Vulnerabilities CVE-2020-25176, CVE-2020-25182, CVE-2020-25184, CVE-2020-25178, CVE-2020-25180. Provide a way for users to manually disable the comm path the ISaGRAF Workbench uses to communicate with the ISaGRAF Runtime in the RTU when not downloading new ISaGRAF RLL programs or debugging those programs. This prevents unauthorized access using this comm path.

Command Log: Fix bug where command log fails to close Syslog socket on RTU side when it detects Syslog server has closed its end. Unclosed sockets could collect eventually to point where it affects system resources, causing RTU reset.​

​Security Enhancement Summary:
No security enhancements in firmware release(s).

Security Fix Summary:
Vulnerability found if using ISaGRAF functionality.  Fix to resolve vulnerability currently scheduled to release by August 2021.  Mitigation instructions are as follows, note that if you are not using ISaGRAF functionality the default is to have all ports disabled and there is no vulnerability.
​
If you are using ISaGRAF RLL programs in the SAGE RTU, the ports will be open, and the firewall will be needed to block access to those ports.  If the Firewall rules are employed, you can verify they are working by trying to connect to the RTU with the ISaGRAF development system.  If the Firewall is implemented and working correctly, the ISaGRAF development system will fail to connect.

Firewall rules used to block access to TCP ports 1113 and 1131:
