• → Exploit targets POST /cms/content/list.do with a crafted sqlWhere parameter containing an UPDATEXML-based error injection payload; detect POST requests to this endpoint with sqlWhere values containing 'updatexml' or 'concat(0x7e'. ↗
• → Successful exploitation returns the MD5 partial hash 'c8c605999f3d8352d7bb792cf3fdb25' (MD5 of 999999999) in the HTTP response body; alert on this string in responses from MCMS endpoints. ↗
• → The vulnerable parameter is 'categoryType' at /content/list.do; monitor for unsanitized or anomalous values in this parameter in HTTP POST bodies. ↗
• → Use Shodan favicon hash 1464851260 or FOFA icon_hash="1464851260" to identify exposed Mingsoft MCMS instances for proactive scanning. ↗
• → Content-Type of the exploit request is application/x-www-form-urlencoded; correlate with POST to /cms/content/list.do for detection. ↗

• · The Nuclei template uses a numeric variable (num=999999999) to generate a deterministic MD5 canary value; the response match string 'c8c605999f3d8352d7bb792cf3fdb25' is specific to this probe value and will not match exploitation using different numeric inputs. ↗
• · The template is configured for a maximum of 2 requests; detection coverage is limited to the specific UPDATEXML error-based injection path and may not cover blind or time-based SQLi variants. ↗
