CVE-2025-8164 is a SQL Injection vulnerability identified in version 1.0 of the code-projects Public Chat Room application, specifically within the send_message.php file. The vulnerability arises from improper sanitization or validation of the 'ID' parameter, which is used in SQL queries. An attacker can remotely manipulate this parameter to inject malicious SQL code, potentially altering the intended database queries. This can lead to unauthorized access, data leakage, modification, or deletion of database records. The vulnerability does not require user interaction or authentication, increasing its exploitability. The CVSS 4.0 score is 5.3 (medium severity), reflecting the fact that while the attack vector is network-based and requires no privileges or user interaction, the impact on confidentiality, integrity, and availability is limited to low levels. No known exploits are currently reported in the wild, and no official patches have been released yet. However, the public disclosure of the vulnerability increases the risk of exploitation by attackers. The vulnerability affects only version 1.0 of the Public Chat Room product, which is a web-based chat application, likely used for real-time communication in various organizational contexts.

For European organizations using code-projects Public Chat Room 1.0, this vulnerability poses a risk of unauthorized database access and manipulation. Attackers exploiting this flaw could extract sensitive chat data, user credentials, or other stored information, compromising confidentiality. They could also alter or delete messages, affecting data integrity and availability of communication records. Given the chat room's role in facilitating communication, disruption or data compromise could impact operational continuity and trust. Organizations in sectors with strict data protection regulations, such as finance, healthcare, or government, face increased compliance risks and potential legal consequences if sensitive data is exposed. The medium severity rating suggests that while the vulnerability is exploitable remotely without authentication, the overall damage potential is somewhat limited, possibly due to the database schema or application context. Nonetheless, the public disclosure and lack of patches increase urgency for mitigation.

European organizations should immediately audit their use of code-projects Public Chat Room to determine if version 1.0 is deployed. If so, they should consider the following specific actions: 1) Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the 'ID' parameter in send_message.php. 2) Apply input validation and parameterized queries or prepared statements in the application code to prevent injection if source code access and modification are possible. 3) Restrict database user permissions to the minimum necessary to limit the impact of any injection attack. 4) Monitor application logs and database activity for unusual queries or access patterns indicative of exploitation attempts. 5) If feasible, isolate or disable the vulnerable chat room service until a patch or updated version is available. 6) Engage with the vendor or community to obtain patches or updates addressing this vulnerability. 7) Educate IT and security teams about this specific vulnerability to enhance detection and response capabilities.
