CVE-2025-13485 identifies a SQL injection vulnerability in the itsourcecode Online File Management System version 1.0, specifically in the processing of the Username parameter within the /ajax.php?action=login endpoint. The vulnerability arises due to insufficient input sanitization, allowing an attacker to inject arbitrary SQL commands remotely without requiring authentication or user interaction. This can lead to unauthorized data access, modification, or deletion within the backend database, potentially compromising confidentiality, integrity, and availability of stored information. The vulnerability has been assigned a CVSS 4.0 score of 6.9, indicating a medium severity level with a network attack vector, low attack complexity, and no privileges or user interaction needed. Although no active exploitation has been reported, a public exploit is available, increasing the likelihood of exploitation attempts. The lack of patches or official remediation increases the urgency for affected organizations to implement mitigations. The vulnerability affects only version 1.0 of the product, which may limit the scope but still poses a significant risk where deployed. The attack surface is exposed via a common login endpoint, making it a prime target for automated scanning and exploitation.

For European organizations using itsourcecode Online File Management System 1.0, this vulnerability poses a risk of unauthorized database access, potentially leading to data breaches involving sensitive files managed by the system. The compromise could result in leakage of confidential information, data tampering, or denial of service through database corruption. Given the remote and unauthenticated nature of the exploit, attackers can launch attacks at scale, increasing the risk of widespread impact. Organizations in sectors such as finance, healthcare, and government, which often handle sensitive documents, are particularly vulnerable. The medium severity rating suggests moderate but tangible risks to business operations and compliance with data protection regulations like GDPR. The public availability of exploits further elevates the threat, necessitating immediate attention to prevent data loss or reputational damage.

Since no official patches are currently available, affected organizations should implement immediate mitigations including: 1) Applying strict input validation and sanitization on the Username parameter to prevent injection; 2) Employing parameterized queries or prepared statements in the backend code to eliminate SQL injection vectors; 3) Restricting network access to the /ajax.php?action=login endpoint via firewalls or web application firewalls (WAFs) to limit exposure; 4) Monitoring logs for suspicious login attempts or unusual SQL errors indicative of injection attempts; 5) Conducting code reviews and penetration testing to identify and remediate similar injection flaws; 6) Considering temporary disabling of the vulnerable login endpoint if feasible until a patch is released; 7) Educating IT staff about the vulnerability and ensuring rapid incident response capabilities. Organizations should also engage with the vendor for updates and patches and plan for timely upgrades once available.
