This article details CVE-2025-64046, a confirmed Cross-Site Scripting (XSS) vulnerability affecting OpenRapid RapidCMS version 1.3.1. The vulnerability resides in the /system/update-run.php file, potentially allowing attackers to inject malicious scripts into the CMS, leading to various security compromises. This poses a significant risk to websites utilizing the affected version.
Technical Details
The vulnerability in /system/update-run.php allows for a malicious actor to inject arbitrary Javascript code which is then executed by other users who have access to this page. This can happen via crafted HTTP requests that inject malicious Javascript code to the page that is not properly sanitized on the server-side.
CVSS Analysis
The Common Vulnerability Scoring System (CVSS) provides a standardized way to assess the severity of vulnerabilities. CVE-2025-64046 has a CVSS score of 6.1 (Medium).
This score reflects the potential for exploitation and the possible impact on confidentiality, integrity, and availability.
Possible Impact
Successful exploitation of this XSS vulnerability can have several severe consequences:
- Account Hijacking: Attackers could steal user session cookies, gaining unauthorized access to accounts.
- Malware Distribution: Malicious scripts could redirect users to websites hosting malware.
- Defacement: The website’s appearance could be altered, damaging its reputation.
