url/admin/ConfigureMailServerSettings?
- →M1: Detect POST-based SQL injection via the mailservername parameter. Look for HTTP requests to /admin/ConfigureMailServerSettings with a request body containing 'name="mailservername"' followed by SQL injection characters (', ", ;, -, \, *, /) or their URL-encoded equivalents (%22, %27, %2a, %2d, %2f, %3b, %5c) in the body after a CRLF.
- →M2: Detect GET-based SQL injection via the mailserverport parameter. Look for HTTP requests to /admin/ConfigureMailServerSettings? with a query string containing 'mailserverport=' followed immediately by SQL injection characters (', ", ;, -, \, *, /) or their URL-encoded equivalents.
- →The vulnerable endpoint is the addMailServerSettings function, reachable via the admin interface. Both inbound HTTP and TLS-decrypted (SSLDecrypt) traffic should be inspected for exploitation attempts.
- ·The Snort/Suricata rules require TLS inspection (SSLDecrypt) to detect exploitation over HTTPS. Without TLS decryption deployed, attacks over encrypted channels will not be detected.
- ·The vulnerability affects Zoho ManageEngine OpManager 12.3 before build 123222 only. Ensure version/build checks are part of asset scoping before deploying detection rules to reduce false positives. ↗
