Noroxi assessment

Priority: Monitor (action score 24/100)

  • 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: 0.33% (FIRST EPSS).
  • Special conditions such as timing or configuration are required.
  • Fixed version: puppet (Debian:11) 2.7.3-3; puppet (Debian:6.0) 2.6.2-5+squeeze1; puppet (RubyGems) 2.7.5, 2.6.11.

Low priority for now. Upgrade to puppet (Debian:11) 2.7.3-3; puppet (Debian:6.0) 2.6.2-5+squeeze1; puppet (RubyGems) 2.7.5, 2.6.11 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Puppet 2.7.x before 2.7.5, 2.6.x before 2.6.11, and 0.25.x, when running in --edit mode, uses a predictable file name, which allows local users to run arbitrary Puppet code or trick a user into editing arbitrary files.
