CWE-134

CVE-2019-7711

by

An issue was discovered in the Interpeak IPCOMShell TELNET server on Green Hills INTEGRITY RTOS 5.0.4. The undocumented shell command “prompt” sets the (user controlled) shell’s prompt value, which is used as a format string input to printf, resulting in an information leak of memory addresses.

CVE-2019-7712

by

An issue was discovered in handler_ipcom_shell_pwd in the Interpeak IPCOMShell TELNET server on Green Hills INTEGRITY RTOS 5.0.4. When using the pwd command, the current working directory path is used as the first argument to printf() without a proper check. An attacker may thus forge a path containing format string modifiers to get a custom format string evaluated. This results in an information leak of memory addresses.

CVE-2019-7715

by

An issue was discovered in the Interpeak IPCOMShell TELNET server on Green Hills INTEGRITY RTOS 5.0.4. The main shell handler function uses the value of the environment variable ipcom.shell.greeting as the first argument to printf(). Setting this variable using the sysvar command results in a user-controlled format string during login, resulting in an information leak of memory addresses.
