CVE-2020-12736: Code42 environments with on-premises server versions 7.0.4 and earlier allow for possible remote code execution.

HighCVSS 7.2 · v3.1—No exploit No fix recorded

Noroxi assessment

Priority: Monitor (action score 29/100)

  • 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: 2% (FIRST EPSS); higher than 81.2% of all records.
  • Anyone who can reach it over the internet can trigger it. Administrator privileges are required. No user action is required. No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Update when a fix is released; follow the vendor's advisory.

Primary sources: NVD · CVE.org · FIRST EPSS

Code42 environments with on-premises server versions 7.0.4 and earlier allow for possible remote code execution. When an administrator creates a local (non-SSO) user via a Code42-generated email, the administrator has the option to modify content for the email invitation. If the administrator entered template language code in the subject line, that code could be interpreted by the email generation services, potentially resulting in server-side code injection.
