Versions before 3.38.0 are vulnerable to Remote Code Execution in the gitserver service. The Gitolite code host integration with Phabricator allows Sourcegraph site admins to specify a `callsignCommand`, which is used to obtain the Phabricator metadata for a Gitolite repository. An administrator who is able to edit or add a Gitolite code host and has administrative access to Sourcegraph\u2019s bundled Grafana instance can change this command arbitrarily and run it remotely. This grants direct access to the infrastructure underlying the Sourcegraph installation. The attack requires: site-admin privileges on the instance of Sourcegraph, Administrative privileges on the bundled Grafana monitoring instance, Knowledge of the gitserver IP address or DNS name (if running in Kubernetes). This can be found through Grafana. The issue is patched in version 3.38.0. You may disable Gitolite code hosts. We still highly encourage upgrading regardless of workarounds."}, {"lang": "es", "value": "Sourcegraph es un motor de b\u00fasqueda y navegaci\u00f3n de c\u00f3digo r\u00e1pido y con muchas funciones. Las versiones anteriores a la 3.38.0 son vulnerables a una ejecuci\u00f3n de c\u00f3digo remota en el servicio gitserver. La integraci\u00f3n del host de c\u00f3digo Gitolite con Phabricator permite a administradores del sitio Sourcegraph especificar un \"callsignCommand\", que es usado para obtener los metadatos de Phabricator para un repositorio Gitolite. Un administrador que es capaz de editar o a\u00f1adir un host de c\u00f3digo Gitolite y presenta acceso administrativo a la instancia de Grafana de Sourcegraph puede cambiar este comando arbitrariamente y ejecutarlo remotamente. Esto garantiza el acceso directo a la infraestructura subyacente a la instalaci\u00f3n de Sourcegraph. El ataque requiere: privilegios de site-admin en la instancia de Sourcegraph, privilegios administrativos en la instancia de monitorizaci\u00f3n de Grafana, conocimiento de la direcci\u00f3n IP del gitserver o del nombre DNS (si es ejecutada en Kubernetes). Esto puede encontrarse mediante Grafana. El problema est\u00e1 parcheado en la versi\u00f3n 3.38.0. Puede deshabilitar los hosts de c\u00f3digo de Gitolite. Seguimos recomendando una actualizaci\u00f3n independientemente de las mitigaciones"}], "lastModified": "2023-07-21T16:42:41.937", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:sourcegraph:sourcegraph:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "50CC52C4-D9CA-4C59-9107-4D5587BF0EFF", "versionEndExcluding": "3.38.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
