CVE-2023-30623

Estado: ModificadaAlta (8.8)—

`embano1/wip` es una GitHub Action escrita en Bash. Antes de la versión 2, la acción `embano1/wip` utiliza el parámetro `github.event.pull_request.title` de forma insegura. El parámetro title se usa en una sentencia run, lo que provoca una vulnerabilidad de inyección de comandos debido a la interpolación de cadenas. Cualquier usuario de GitHub puede desencadenar esta vulnerabilidad. Solo necesita crear una pull request con un mensaje de commit que contenga un exploit.

Leer descripción completaMostrar menos

(Tenga en cuenta que las pull requests de usuarios que contribuyen por primera vez no se ejecutarán, pero el atacante puede enviar una PR válida antes de enviar una PR no válida). El commit puede ser auténtico, pero el mensaje del commit puede ser malicioso. Esto puede utilizarse para ejecutar código en los runners de GitHub y para exfiltrar cualquier secreto utilizado en el pipeline de CI, incluidos los tokens del repositorio. La versión 2 corrige este problema.

The title parameter is used in a run statement - resulting in a command injection vulnerability due to string interpolation. This vulnerability can be triggered by any user on GitHub. They just need to create a pull request with a commit message containing an exploit. (Note that first-time PR requests will not be run - but the attacker can submit a valid PR before submitting an invalid PR). The commit can be genuine, but the commit message can be malicious. This can be used to execute code on the GitHub runners and can be used to exfiltrate any secrets used in the CI pipeline, including repository tokens. Version 2 has a fix for this issue."
