来源: CVE Program / CVE List V5
Vulnerability Description
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.

| 2 | Gitea 1.1.0 through 1.12.5 is susceptible to authenticated remote code execution, via the git hook functionality, in customer environments where the documentation is 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 subset of accounts.

We provide very clear warnings to users around this functionality and what it provides." | https://github.com/projectdiscovery/nuclei-templates/blob/main/http/cves/2020/CVE-2020-14144.yaml | POC详情 |
| 3 | Gitea versions 1.1.0 → 1.12.5 allow authenticated users with "May create git hooks" permission to inject arbitrary shell commands into post-receive hooks. Pushing a commit triggers the hook and executes the payload on the server. | https://github.com/Mohnad-AL-saif/Gitea-Git-Hooks-RCE-CVE-2020-14144- | POC详情 |
