Apache HTTP Server 2.4.53 and earlier may not send the X-Forwarded-* headers to the origin server based on client side Connection header hop-by-hop mechanism. This may be used to bypass IP based authentication on the origin server/application.

An Improper Input Validation vulnerability exists in Trihedral VTScada version 12.0.38 and prior. A specifically malformed HTTP request could cause the affected VTScada to crash. Both local area network (LAN)-only and internet facing systems are affected.

A vulnerability has been identified in SiPass integrated AC5102 (ACC-G2) (All versions < V2.85.44), SiPass integrated ACC-AP (All versions < V2.85.43). Affected devices improperly sanitize user input on the telnet command line interface. This could allow an authenticated user to escalate privileges by injecting arbitrary commands that are executed with root privileges.

In CODESYS V2 PLCWinNT and Runtime Toolkit 32 in versions prior to V2.4.7.57 password protection is not enabled by default and there is no information or prompt to enable password protection at login in case no password is set at the controller.

In the CODESYS Development System multiple components in multiple versions transmit the passwords for the communication between clients and servers unprotected.
