Admidio — Vulnerabilities & Security Advisories 60

Admidio is an open-source community management system designed to facilitate the administration of clubs, associations, and organizations by handling member data, event scheduling, and resource allocation. Despite its utility, the software has a significant security history, with twenty-seven Common Vulnerabilities and Exposures (CVEs) documented to date. These flaws predominantly involve SQL injection, cross-site scripting (XSS), and broken access control mechanisms, which frequently allow unauthenticated attackers to execute remote code or escalate privileges. The application’s reliance on older PHP frameworks and inconsistent input validation has historically exposed it to severe exploitation. While recent updates have addressed critical gaps, the cumulative impact of these vulnerabilities suggests a pattern of delayed patching for legacy code paths. Organizations deploying this platform must prioritize strict access controls and regular vulnerability assessments to mitigate the risk of data breaches and unauthorized system modifications inherent in its previous versions.
