Noroxi assessment

Priority: This week (action score 60/100)

  • A ready-made attack module is public (Metasploit); exploiting it takes no special expertise.
  • A ready-made attack tool exists and the flaw can be exploited over the network without an account, so priority is at least “This week”.
  • Probability of exploitation in the next 30 days: 95.3% (FIRST EPSS); higher than 99.8% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: openssl (Debian:12) 1.0.1h-1; openssl (Debian:6.0) 0.9.8o-4squeeze15, 0.9.8o-4squeeze16; openssl (Debian:7) 1.0.1e-2+deb7u10.

Don’t wait for the next maintenance window. Upgrade to openssl (Debian:12) 1.0.1h-1; openssl (Debian:6.0) 0.9.8o-4squeeze15, 0.9.8o-4squeeze16; openssl (Debian:7) 1.0.1e-2+deb7u10 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h does not properly restrict processing of ChangeCipherSpec messages, which allows man-in-the-middle attackers to trigger use of a zero-length master key in certain OpenSSL-to-OpenSSL communications, and consequently hijack sessions or obtain sensitive information, via a crafted TLS handshake, aka the "CCS Injection" vulnerability.
