MediumCVSS 4.9 · v4.0—No exploit No fix recorded

Noroxi assessment

Priority: Monitor (action score 20/100)

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: 2.5% (FIRST EPSS); higher than 85.2% of all records.
Someone on the same network segment can trigger it. No account or password is required. No user action is required. Special conditions such as timing or configuration are required.
According to the record, no fixed version is available yet.

Low priority for now. Update when a fix is released; follow the vendor's advisory.
