CVE-2023-24488: Cross site scripting

Noroxi assessment

Priority: Plan (action score 48/100)

  • A ready-made attack module is public (Nuclei); exploiting it takes no special expertise.
  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 81.1% (FIRST EPSS); higher than 99.6% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: Citrix Citrix ADC and Citrix Gateway 12.1-55.296, 12.1-65.35, 13.0-90.11 .
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Add it to your regular patch cycle. Upgrade to Citrix Citrix ADC and Citrix Gateway 12.1-55.296, 12.1-65.35, 13.0-90.11  or later.

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.
