id: CVE-2020-15718

info:
  name: RosarioSIS 6.7.2 - Cross-Site Scripting
  author: 0xr2r,jarvis-survives
  severity: medium
  description: |
    RosarioSIS version 6.7.2 and earlier contains a reflected cross-site scripting (XSS) vulnerability in the Preferences module. The 'tab' parameter in Modules.php is not properly sanitized, allowing an attacker to inject arbitrary JavaScript code via a crafted URL.
  impact: |
    An attacker can execute arbitrary JavaScript in the context of a victim's browser session, potentially leading to session hijacking, credential theft, or other malicious actions.
  remediation: |
    Update RosarioSIS to the latest version where input validation has been improved.
