Noroxi assessment

Priority: Monitor (action score 22/100)

  • 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: 8.3% (FIRST EPSS); higher than 95% of all records.
  • No special conditions are required; it is repeatable.
  • Fixed version: openssl (Debian:12) 1.0.1k-2; openssl (Debian:6.0) 0.9.8o-4squeeze20; openssl (Debian:7) 1.0.1e-2+deb7u15.

Low priority for now. Upgrade to openssl (Debian:12) 1.0.1k-2; openssl (Debian:6.0) 0.9.8o-4squeeze20; openssl (Debian:7) 1.0.1e-2+deb7u15 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

The X509_to_X509_REQ function in crypto/x509/x509_req.c in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a might allow attackers to cause a denial of service (NULL pointer dereference and application crash) via an invalid certificate key.
