Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly mitigates SQL injection by requiring validation of untrusted inputs like the 'id' argument in /user/leaveroom.php to prevent improper neutralization of SQL special elements.
Ensures timely identification, reporting, and correction of flaws such as this SQL injection vulnerability through systematic remediation processes.
Enables vulnerability scanning to identify SQL injection issues like CWE-89 in the chat system's /user/leaveroom.php endpoint.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Direct remote SQL injection in a web application enables exploitation of public-facing apps (T1190) for limited data access/modification.

Deeper analysisAI
CVE-2025-0531 is a critical SQL injection vulnerability in code-projects Chat System 1.0, affecting the processing of the /user/leaveroom.php file. The issue arises from improper handling of the 'id' argument, allowing manipulation that leads to SQL injection as classified under CWE-74 (Improper Neutralization of Special Elements used in an SQL Command) and CWE-89 (SQL Injection). The vulnerability has a CVSS v3.1 base score of 6.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L) and was published on 2025-01-17.
The vulnerability can be exploited remotely by attackers with low privileges, such as authenticated users, due to the low attack complexity and lack of required user interaction. Successful exploitation enables limited confidentiality, integrity, and availability impacts through SQL injection, potentially allowing unauthorized data access, modification, or disruption within the chat system's database.
Advisories referenced in VulDB entries (ctiid.292415, id.292415, submit.478688) document the issue, while a GitHub repository (LamentXU123/cve/blob/main/sql_injection2.md) discloses a public exploit. The code-projects.org site hosts the affected Chat System 1.0 software, but no specific patches or mitigations are detailed in the provided information. The exploit has been made publicly available and may be used by attackers.
