Noroxi assessment

Priority: Monitor (action score 25/100)

  • 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: 1.4% (FIRST EPSS); higher than 74.6% of all records.
  • No special conditions are required; it is repeatable.
  • Fixed version: radsecproxy (Debian:12) 1.6.2-1; radsecproxy (Debian:6.0) 1.4-1+squeeze1.

Low priority for now. Upgrade to radsecproxy (Debian:12) 1.6.2-1; radsecproxy (Debian:6.0) 1.4-1+squeeze1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

The DTLS support in radsecproxy before 1.6.2 does not properly verify certificates when there are configuration blocks with CA settings that are unrelated to the block being used for verifying the certificate chain, which might allow remote attackers to bypass intended access restrictions and spoof clients, a different vulnerability than CVE-2012-4523.
