Vision Helpdesk Serialized IDOR and Session Prediction Vulnerability Analysis

Vulnerability Summary: Vision Helpdesk Critical Vulnerabilities Overview Vulnerability Name: Serialized IDOR and Session Prediction Affected Software: Vision Helpdesk Vulnerability Type: Insecure Direct Object Reference (IDOR) Root Cause: Vision Helpdesk uses a cookie named to manage sessions. This cookie is a Base64-encoded serialized object containing the field. An attacker can decode the cookie, modify the value of (e.g., increment or decrement it), re-encode it, and replace the original cookie, thereby impersonating other users without authentication. Impact Scope Severity: Critical Impact: Attackers can perform session hijacking by modifying the in the cookie, directly accessing other users’ accounts without authentication. Affected Versions: Versions prior to 5.6.10. Remediation Official Patch: The vendor has confirmed the vulnerability and fixed it in version 5.6.10. Temporary Mitigation Measures: Disable affected scripts. Implement access control measures (e.g., IP whitelisting) until the vendor releases the patch. Proof-of-Concept (PoC) Extraction Note: A downloadable PoC script link is provided on the page, but the code content is not directly shown in the screenshot. According to the description, this script is used to test whether an installation is vulnerable to the serialized IDOR issue.*
