CVE-2025-63585 identifies a SQL Injection vulnerability in OSSN (Open Source Social Network) version 8.6, specifically in the /action/rtcomments/status endpoint through the timestamp parameter. SQL Injection (CWE-89) occurs when untrusted input is improperly sanitized, allowing attackers to manipulate backend SQL queries. This vulnerability is remotely exploitable without authentication or user interaction, increasing its risk profile. An attacker can craft malicious input in the timestamp parameter to execute arbitrary SQL commands, potentially extracting sensitive data or altering database contents. The CVSS v3.1 score of 6.5 reflects a medium severity, indicating that while the vulnerability can compromise confidentiality and integrity, it does not impact availability. No patches or known exploits are currently documented, but the exposure of social network data could have privacy and reputational consequences. The vulnerability’s presence in a social networking platform underscores the risk of user data leakage or manipulation, which could be leveraged for further attacks or misinformation campaigns.

For European organizations, the impact of this vulnerability includes potential unauthorized access to user data stored within OSSN platforms, risking privacy violations under GDPR and other data protection regulations. Integrity compromise could allow attackers to modify user comments or statuses, undermining trust and platform reliability. While availability is not directly affected, reputational damage and regulatory penalties could be significant. Organizations operating social networks, community forums, or customer engagement portals using OSSN 8.6 are particularly at risk. The ability to exploit this vulnerability without authentication increases exposure, especially for public-facing installations. The lack of known exploits currently reduces immediate risk but does not eliminate the threat, as attackers may develop exploits in the future. European entities must consider the legal and operational consequences of data breaches resulting from this vulnerability.

To mitigate CVE-2025-63585, organizations should implement strict input validation and sanitization on the timestamp parameter to prevent injection of malicious SQL code. Employing parameterized queries or prepared statements in the backend database interactions is critical to eliminate SQL Injection risks. Since no official patches are currently available, applying Web Application Firewalls (WAFs) with custom rules to detect and block suspicious SQL injection patterns targeting the /action/rtcomments/status endpoint can provide interim protection. Regularly audit and monitor database logs for unusual query patterns or access anomalies. Organizations should also review and restrict database user privileges to minimize potential damage from successful injections. Finally, maintain awareness of OSSN updates and apply official patches promptly once released. Conducting security assessments and penetration testing focused on injection flaws will help identify and remediate similar vulnerabilities proactively.
