path application/controllers/admin/export.php↗

• → Monitor HTTP requests targeting the downloadZip/szip functionality in LimeSurvey's export controller for path traversal sequences (e.g., '../') in parameters, indicating exploitation of CVE-2019-9960. ↗
• → Alert on authenticated POST/GET requests to application/controllers/admin/export.php containing relative path components, as this is the vulnerable endpoint for CVE-2019-9960. ↗
• → The Metasploit auxiliary module limesurvey_zip_traversals.rb can be used to verify exposure; detect its use by correlating scanner activity against LimeSurvey admin endpoints. ↗

• · Exploitation requires authentication; unauthenticated access to the vulnerable endpoint is not sufficient to trigger CVE-2019-9960. ↗
• · CVE-2019-9960 affects LimeSurvey versions up to and including 3.15.9 (and up to 3.16.1+190225 per NVD); distinguish from CVE-2020-11455 which affects 4.0–4.1.11 and uses a different vulnerable function (getZipFile in filemanager). ↗
