Noroxi assessment

Priority: Plan (action score 50/100)

  • Public proof-of-concept code exists (Exploit-DB, GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 89% (FIRST EPSS); higher than 99.7% 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 (Alpine:v3.2) 1.0.2h-r0; openssl (Debian:12) 1.0.2h-1; openssl (Debian:7) 1.0.1e-2+deb7u21.

Add it to your regular patch cycle. Upgrade to openssl (Alpine:v3.2) 1.0.2h-r0; openssl (Debian:12) 1.0.2h-1; openssl (Debian:7) 1.0.1e-2+deb7u21 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

The AES-NI implementation in OpenSSL before 1.0.1t and 1.0.2 before 1.0.2h does not consider memory allocation during a certain padding check, which allows remote attackers to obtain sensitive cleartext information via a padding-oracle attack against an AES CBC session. NOTE: this vulnerability exists because of an incorrect fix for CVE-2013-0169.
