PAN-OS: Stored Cross-Site Scripting (XSS) Vulnerability in the Web Interface

Noroxi assessment

Priority: Monitor (action score 19/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.41% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. Administrator privileges are required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: Palo Alto Networks PAN-OS 10.1.11, 10.2.5, 11.0.2.

Low priority for now. Upgrade to Palo Alto Networks PAN-OS 10.1.11, 10.2.5, 11.0.2 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 cross-site scripting (XSS) vulnerability in Palo Alto Networks PAN-OS software enables a malicious authenticated read-write administrator to store a JavaScript payload using the web interface. Then, when viewed by a properly authenticated administrator, the JavaScript payload executes and disguises all associated actions as performed by that unsuspecting authenticated administrator.
