CVE-2025-5119 is a critical SQL Injection vulnerability identified in Emlog Pro version 2.5.11, specifically within the /include/controller/api_controller.php file. The vulnerability arises from improper sanitization or validation of the 'tag' parameter, which can be manipulated remotely by an unauthenticated attacker to inject malicious SQL code. This injection flaw allows attackers to interfere with the queries that the application makes to its backend database, potentially enabling unauthorized data access, data modification, or even complete compromise of the database. The vulnerability does not require any user interaction or authentication, making it highly exploitable over the network. Although the CVSS 4.0 score rates this vulnerability as medium severity (6.9), the nature of SQL Injection vulnerabilities generally poses significant risks to confidentiality, integrity, and availability of data. The vendor has been notified and confirmed the vulnerability, but no patch or mitigation guidance has been publicly provided yet. No known exploits are currently observed in the wild, but public disclosure increases the risk of exploitation attempts. Given the critical nature of SQL Injection flaws and the direct remote attack vector, this vulnerability demands urgent attention from organizations using Emlog Pro 2.5.11 to prevent potential data breaches or system compromise.

For European organizations using Emlog Pro 2.5.11, this vulnerability could lead to severe consequences including unauthorized access to sensitive data, data corruption, or complete database compromise. This may result in loss of customer trust, regulatory penalties under GDPR for data breaches, and operational disruptions. Organizations in sectors such as finance, healthcare, government, and e-commerce, which often rely on web content management systems like Emlog Pro, are particularly at risk. The ability to exploit this vulnerability remotely without authentication increases the attack surface, potentially allowing attackers to bypass perimeter defenses. Additionally, the public disclosure of the vulnerability may accelerate exploitation attempts targeting European entities, especially those with limited patch management capabilities or insufficient web application security controls.

European organizations should immediately audit their use of Emlog Pro to identify any instances of version 2.5.11. Until an official patch is released, organizations should implement the following mitigations: 1) Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the 'tag' parameter in API requests. 2) Conduct thorough input validation and sanitization on all user-supplied data, especially the 'tag' parameter, to neutralize injection payloads. 3) Restrict direct internet access to the vulnerable API endpoints where feasible, limiting exposure to trusted networks only. 4) Monitor logs for unusual database query patterns or errors indicative of injection attempts. 5) Prepare for rapid deployment of vendor patches once available and test updates in controlled environments before production rollout. 6) Consider temporary disabling or restricting the vulnerable API functionality if it is not critical to business operations. These targeted actions go beyond generic advice by focusing on the specific vulnerable parameter and attack vector.
