Noroxi assessment

Priority: Plan (action score 57/100)

  • A ready-made attack module is public (Metasploit, Nuclei); exploiting it takes no special expertise.
  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 95.4% (FIRST EPSS); higher than 99.8% 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.
  • Fixed version: code.gitea.io/gitea (Go) 1.12.6.

Add it to your regular patch cycle. Upgrade to code.gitea.io/gitea (Go) 1.12.6 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

The git hook feature in Gitea 1.1.0 through 1.12.5 might allow for authenticated remote code execution in customer environments where the documentation was not understood (e.g., one viewpoint is that the dangerousness of this feature should be documented immediately above the ENABLE_GIT_HOOKS line in the config file). NOTE: The vendor has indicated this is not a vulnerability and states "This is a functionality of the software that is limited to a very limited subset of accounts. If you give someone the privilege to execute arbitrary code on your server, they can execute arbitrary code on your server. We provide very clear warnings to users around this functionality and what it provides.
