The CVE-2025-5888 vulnerability in jsnjfz WebStack-Guns version 1.0 is a cross-site request forgery (CSRF) flaw that allows remote attackers to execute unauthorized actions by tricking authenticated users into submitting malicious requests. The application fails to implement adequate anti-CSRF tokens or same-origin validation for state-changing operations. When an authenticated user visits a malicious webpage crafted by an attacker, embedded scripts or forms automatically submit requests to the vulnerable WebStack-Guns application, leveraging the user’s existing session credentials. This manipulation targets unknown functionalities within the software, potentially enabling actions like account settings modification, data manipulation, or administrative changes without user consent. The attack vector is network-based, requires no user interaction beyond browsing, and exploits the lack of request verification. Public disclosure of the exploit increases risk, as attackers can replicate the method using simple HTTP POST or GET requests that mimic legitimate ones. The vendor’s lack of response indicates unpatched code, leaving systems exposed to CSRF attacks where attacker-controlled requests are processed as authentic due to session cookie inclusion. The CVSS 4.0 score reflects medium severity due to the potential for integrity impact and low attack complexity.
Platform: WebStack-Guns
Version: 1.0
Vulnerability: Cross-Site Request Forgery
Severity: Medium
date: 06/09/2025
Prediction: No patch expected
What Undercode Say:
Analytics
curl -X POST -H "Content-Type: application/x-www-form-urlencoded" -d "action=delete&id=1" http://target/endpoint <html> <body> <form action="http://target/endpoint" method="POST"> <input type="hidden" name="action" value="modify"> </form> <script>document.forms[bash].submit();</script> </body> </html>
How Exploit:
Attackers host malicious sites with auto-submitting forms targeting WebStack-Guns endpoints, exploiting authenticated sessions to perform unauthorized state-changing operations like data deletion or profile updates without user knowledge.
Protection from this CVE
Implement anti-CSRF tokens, validate SameSite cookies, use referer headers, and employ framework-specific protections like synchronizer patterns to ensure requests originate from intended sources.
Impact:
Unauthorized data manipulation, account takeover, or administrative changes compromising system integrity and confidentiality for authenticated users.
