PAN-OS: Denial of Service (DoS) on Panorama

Noroxi assessment

Priority: Monitor (action score 18/100)

  • 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: 0.31% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Palo Alto Networks PAN-OS 11.1.10-h35, 11.1.13-h15, 11.1.16-h3.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Palo Alto Networks PAN-OS 11.1.10-h35, 11.1.13-h15, 11.1.16-h3 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

A stack-based buffer overflow vulnerability in the log processing functionality of Palo Alto Networks PAN-OS® software on Panorama enables an attacker to cause a denial of service (DoS) condition. Repeated attempts to trigger this condition result in the Panorama entering maintenance mode. Cloud NGFW, Prisma® Access, and standalone PAN-OS firewalls are not affected by this vulnerability.
