AI Analysis

Impact

An attacker can inject malicious JavaScript in the 'to' and 'tag' parameters of the postThread.jsp page, breaking out of unencoded inline JavaScript string literals. The affected script runs within the victim’s browser session, enabling attackers to steal session cookies, deface content, or perform further actions on behalf of the authenticated user. This is a typical reflected cross‑site scripting weakness (CWE‑79).

Affected Systems

The vulnerability is present in all versions of the Jivejdon application up to and including version 5.0, as distributed by banq.

Risk and Exploitability

The vulnerability has a CVSS base score of 5.3, indicating moderate severity. No EPSS score is available, and the issue is not listed in the CISA KEV catalog. The likely attack vector is a phishing link that an authenticated user clicks, delivering the crafted payload. Although the exploitation requires the victim to visit the crafted link, the impact within the user’s session can be significant.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Upgrade the Jivejdon installation to any version newer than 5.0 where the patch is applied.
  • If an upgrade is not currently possible, apply input sanitization on the 'to' and 'tag' parameters to encode or strip potentially executable characters before rendering them.
  • Configure a strict Content Security Policy for the application to disallow inline scripts, thereby limiting the damage of any XSS payload.
