The detection rule for CVE-2024-13161 targets the specific endpoint /WSVulnerabilityCore/VulCore.asmx and checks for the presence of a UNC path in the wildcard XML element within the SOAP request body. This path is indicative of an NTLM credential coercion attack, where an attacker specifies a remote UNC path to trigger NTLM authentication. The rule uses a regex match to detect any UNC path that includes a temporary directory and a .txt file, which aligns with the attack vector described in the vulnerability. The rule is designed to be case insensitive and to specifically match the structure of the attack, minimizing false positives while ensuring effective detection.
