Noroxi assessment

Priority: Monitor (action score 23/100)

  • 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: 18.3% (FIRST EPSS); higher than 97.2% of all records.
  • Fixed version: openssl (Debian:12) 1.0.1i-1; openssl (Debian:6.0) 0.9.8o-4squeeze17; openssl (Debian:7) 1.0.1e-2+deb7u12.

Low priority for now. Upgrade to openssl (Debian:12) 1.0.1i-1; openssl (Debian:6.0) 0.9.8o-4squeeze17; openssl (Debian:7) 1.0.1e-2+deb7u12 or later.

The ssl3_send_client_key_exchange function in s3_clnt.c in OpenSSL 0.9.8 before 0.9.8zb, 1.0.0 before 1.0.0n, and 1.0.1 before 1.0.1i allows remote DTLS servers to cause a denial of service (NULL pointer dereference and client application crash) via a crafted handshake message in conjunction with a (1) anonymous DH or (2) anonymous ECDH ciphersuite.
