Noroxi assessment
Priority: Monitor (action score 21/100)
- 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: 0.36% (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.
- According to CISA the attack is automatable: targets can be found by mass scanning.
- Fixed version: Axis Communications AB AXIS OS 10.12.270, 11.11.127, 12.3.4.
Low priority for now. Upgrade to Axis Communications AB AXIS OS 10.12.270, 11.11.127, 12.3.4 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
Dzmitry Lukyanenka, member of the AXIS OS Bug Bounty Program, has found that the VAPIX API param.cgi was vulnerable to a race condition attack allowing for an attacker to block access to the web interface of the Axis device. Other API endpoints or services not making use of param.cgi are not affected. Axis has released patched AXIS OS versions for the highlighted flaw. Please refer to the Axis security advisory for more information and solution.
