Name of the Vulnerable Software and Affected Versions Green Hills INTEGRITY RTOS version 5.0.4

Description A heap-based buffer overflow issue exists in the Interpeak IPCOMShell TELNET server. This occurs when a custom modifier is used to display specific information, such as a process ID, IP address, or current working directory, triggering modifier expansion. The overflow causes memory corruption or a crash and also leaks memory address information.

Recommendations For Green Hills INTEGRITY RTOS version 5.0.4, consider disabling the custom modifier expansion in the Interpeak IPCOMShell TELNET server as a temporary workaround to minimize the risk of exploitation.
