url /be/erpc.php?c=../../../../../fspath/of/uploaded/file/rce.php↗

• → Monitor HTTP requests to /be/erpc.php containing directory traversal sequences (e.g., '../') in the 'c' query parameter, which is the exploitation vector for RCE. ↗
• → Detect POST requests to /be/erpc.php with a 'c' parameter value containing path traversal patterns as an indicator of active exploitation attempts. ↗
• → Alert on HTTP responses from Jedox file upload endpoints (e.g., Designer Import) that return a JSON body containing 'fspath', as attackers use this to retrieve the server-side path of uploaded files prior to exploitation. ↗
• → Flag upload of PHP files through Jedox file upload mechanisms (e.g., Import in Designer), as this is a prerequisite step for achieving RCE via the directory traversal vulnerability. ↗

• · Exploitation requires the attacker to be authenticated AND have file upload permissions (e.g., Import in Designer). Unauthenticated users cannot directly exploit this vulnerability. ↗
• · Affected versions include Jedox 2022.4 (22.4.2) and older, as well as the specifically named Jedox 2020.2.5. Patch or upgrade beyond these versions to remediate. ↗
