• → Detect exploitation attempts by monitoring POST requests to /cms/content/list containing SQL injection patterns in the categoryId parameter, specifically GTID_SUBSET or CONCAT with hex-encoded canary strings.
• → A successful blind SQL injection probe returns the partial MD5 string 'c8c605999f3d8352d7bb792cf' in the HTTP response body (md5 of 999999999); match this string in response bodies to confirm exploitation.
• → The endpoint is unauthenticated (PR:N); no session cookie or auth header is required, so any POST to /cms/content/list with a manipulated categoryId should be treated as suspicious.
• → Use Shodan favicon hash 1464851260 or FOFA icon_hash="1464851260" to identify exposed Mingsoft MCMS instances for proactive asset discovery.
• → HTTP response status codes 200 or 500 are both considered indicative of a successful injection probe against this endpoint.

• · The vulnerability is limited to Mingsoft MCMS version 5.2.7 specifically; other versions may not be affected. ↗
• · The SQL injection payload uses MySQL-specific GTID_SUBSET function; this detection logic applies only to MySQL-backed deployments of MCMS.
