Noroxi assessment

Priority: Monitor (action score 25/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.37% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: osTicket osTicket 1.17.8, 1.18.4.

Low priority for now. Upgrade to osTicket osTicket 1.17.8, 1.18.4 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

osTicket versions from 1.10 up to 1.17.7 and from 1.18.0 up to 1.18.3 are vulnerable to a stored XSS due to a vulnerable Bootstrap Tooltip component and insufficient HTML sanitization, allowing remote attackers to execute arbitrary JavaScript in Agent or Admin sessions.

Limit the impact of XSS

This is a cross-site scripting (XSS) vulnerability. A well-configured Content-Security-Policy doesn't fix it, but greatly reduces its impact. Check your site's CSP and other security headers for free.
