Potential Exploitation Attempt From Office Application Using Directory Traversal
Detects Microsoft Office applications executing child processes that include directory traversal patterns in their command line. This behavior is indicative of exploitation attempts, specifically referencing vulnerabilities like CVE-2022-30190 (MSDT RCE, also known as Follina) and CVE-2021-40444 (MSHTML RCE). The rule looks for common Office applications as parent processes and specific directory traversal strings in the child process's command line.
