CVE-2022-39048: Cross-Site Scripting (XSS) vulnerability in ServiceNow UI page assessment_redirect

Noroxi assessment

Priority: Monitor (action score 24/100)

  • A ready-made attack module is public (Nuclei); exploiting it takes no special expertise.
  • Public proof-of-concept code exists (Exploit-DB / GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 1% (FIRST EPSS); higher than 65.6% 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: Servicenow Now Platform Patch 2, Patch 9.

Low priority for now. Upgrade to Servicenow Now Platform Patch 2, Patch 9 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

A XSS vulnerability was identified in the ServiceNow UI page assessment_redirect. To exploit this vulnerability, an attacker would need to persuade an authenticated user to click a maliciously crafted URL. Successful exploitation potentially could be used to conduct various client-side attacks, including, but not limited to, phishing, redirection, theft of CSRF tokens, and use of an authenticated user's browser or session to attack other systems.
