Blind SQL Injection in Admidio List Parameter

Admidio before 5.0.12 contains a blind SQL injection vulnerability in the relation_type_list parameter of lists_show.php that allows unauthenticated attackers to execute arbitrary SQL queries. Attackers can bypass authentication by providing a dummy UUID in role_list and inject SQL through relation_type_list to extract database contents including password hashes and user credentials.

Casky was already ahead

This CVE exploits attack patterns that Casky's 323matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.

Analysis

Admidio versions before 5.0.12 contain a blind SQL injection vulnerability in the lists_show.php file's relation_type_list parameter. This unauthenticated flaw allows attackers to execute arbitrary SQL queries by bypassing authentication through a dummy UUID in the role_list parameter. The vulnerability is particularly dangerous because it grants direct access to the database layer, enabling attackers to extract sensitive information including password hashes, user credentials, and other confidential data. Organizations running Admidio—a community management platform commonly deployed by nonprofits, associations, and local groups—face immediate risk of credential compromise and complete database exfiltration without requiring valid user credentials.

Casky's 323 matched skills leverage Claude AI's extended reasoning to detect the attack patterns underlying this CVE across MITRE ATT&CK techniques TA0001 (Initial Access) and TA0043 (Reconnaissance). Practitioners using Casky would observe detection findings focused on: SQL metacharacter sequences and UNION-based payloads in HTTP parameters, authentication bypass indicators where unauthenticated requests succeed with injected role_list values, and abnormal database query patterns characteristic of blind SQL injection (time-based delays, boolean-based conditional responses, or error-based extraction). The platform's skill mapping would highlight how attackers combine reconnaissance activities to identify vulnerable parameters with initial access exploitation, helping security teams recognize the complete attack chain and prioritize Admidio instance patching and input validation hardening.
