HighCVSS 7.5 · v3.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 39/100)

  • 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: 29.9% (FIRST EPSS); higher than 98.2% 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. No special conditions are required; it is repeatable.
  • Fixed version: openssl (Alpine:v3.2) 1.0.2h-r2; openssl (Debian:12) 1.0.2i-1; openssl (Debian:7) 1.0.1t-1+deb7u1.

Low priority for now. Upgrade to openssl (Alpine:v3.2) 1.0.2h-r2; openssl (Debian:12) 1.0.2i-1; openssl (Debian:7) 1.0.1t-1+deb7u1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

The TS_OBJ_print_bio function in crypto/ts/ts_lib.c in the X.509 Public Key Infrastructure Time-Stamp Protocol (TSP) implementation in OpenSSL through 1.0.2h allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted time-stamp file that is mishandled by the "openssl ts" command.
