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: 0.31% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: botan1.10 (Debian:7) 1.10.5-1+deb7u4; botan1.10 (Debian:9) 1.10.17-1+deb9u1; Botan (openSUSE:Tumbleweed) 2.18.1-1.3.

Low priority for now. Upgrade to botan1.10 (Debian:7) 1.10.5-1+deb7u4; botan1.10 (Debian:9) 1.10.17-1+deb9u1; Botan (openSUSE:Tumbleweed) 2.18.1-1.3 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

A cryptographic cache-based side channel in the RSA implementation in Botan before 1.10.17, and 1.11.x and 2.x before 2.3.0, allows a local attacker to recover information about RSA secret keys, as demonstrated by CacheD. This occurs because an array is indexed with bits derived from a secret key.
