Noroxi assessment
Priority: Monitor (action score 38/100)
- 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: 1% (FIRST EPSS); higher than 63.9% of all records.
- Someone on the same network segment can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
- According to the record, no fixed version is available yet.
- Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).
Low priority for now. Update when a fix is released; follow the vendor's advisory.
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 command injection vulnerability exists in CLI of the affected HPE Networking Instant ON APs that could allow an unauthenticated adjacent attacker to perform command injection by sending specially crafted packets. Successful exploitation could allow an attacker to execute arbitrary commands as a privileged user on the underlying operating system.
