CVE-2025-62617 in admidio
Summary
by MITRE • 10/23/2025
Admidio is an open-source user management solution. Prior to version 4.3.17, an authenticated SQL injection vulnerability exists in the member assignment data retrieval functionality of Admidio. Any authenticated user with permissions to assign members to a role (such as an administrator) can exploit this vulnerability to execute arbitrary SQL commands. This can lead to a full compromise of the application's database, including reading, modifying, or deleting all data. This issue has been patched in version 4.3.17.

The vulnerability CVE-2025-62617 represents a critical authenticated SQL injection flaw within the Admidio user management platform that affects versions prior to 4.3.17. This security weakness resides in the member assignment data retrieval functionality, which is a core component of the application's role-based access control system. The flaw allows authenticated users with appropriate permissions to manipulate database queries through input validation bypass techniques, effectively undermining the application's security controls. The vulnerability specifically targets the data handling mechanisms used when assigning members to roles, making it particularly dangerous for administrators who possess elevated privileges within the system.
The technical implementation of this SQL injection vulnerability stems from inadequate input sanitization and improper parameter handling within the member assignment functionality. When authenticated users interact with the role assignment features, the application fails to properly escape or validate user-supplied data before incorporating it into database queries. This creates an exploitation vector where malicious input can alter the intended query structure, allowing attackers to inject arbitrary SQL commands. The vulnerability falls under CWE-89 which specifically addresses SQL injection flaws, and aligns with ATT&CK technique T1078.101 for Valid Accounts and T1566.001 for Phishing as attackers would need legitimate credentials to exploit this vulnerability, though the impact extends far beyond simple account compromise.
The operational impact of this vulnerability is severe and potentially catastrophic for organizations relying on Admidio for user management. An authenticated attacker with member assignment permissions can gain complete control over the application's database backend, enabling them to read sensitive user information, modify existing records, delete critical data, or even escalate privileges within the database. The compromise extends to all user accounts, membership data, and role assignments stored within the system. This vulnerability essentially provides an attacker with a backdoor to the entire user management infrastructure, potentially affecting not just individual users but entire organizational structures that depend on the platform for membership coordination and access control. The lack of proper input validation in this critical functionality means that even authorized users could inadvertently facilitate data breaches or system corruption.
Organizations using affected versions of Admidio must immediately implement the patch released in version 4.3.17 to remediate this vulnerability. The fix addresses the root cause by implementing proper input sanitization and parameterized query execution throughout the member assignment functionality. System administrators should also conduct comprehensive security audits to identify any potential exploitation attempts and review access controls to ensure that only necessary users possess member assignment permissions. Additional mitigations include implementing network segmentation to limit access to the application, deploying intrusion detection systems to monitor for suspicious database query patterns, and establishing robust logging mechanisms to track member assignment activities. The vulnerability demonstrates the critical importance of input validation in web applications and highlights how even authenticated users with legitimate access can pose significant security risks when proper sanitization controls are absent from core application functions.
