Summary
Missing input validation in internal/db/repo_editor.go in Gogs before 0.12.8 allows an attacker to execute code remotely. An unprivileged attacker (registered user) can overwrite the Git configuration in his repository. This leads to Remote Command Execution, because that configuration can contain an option such as sshCommand, which is executed when a master branch is a remote branch (using an ssh:// URI). The remote branch can also be configured by editing the Git configuration file. One can create a new file in a new repository, using the GUI, with "\" as its name, and then rename this file to .git/config with the custom configuration content (and then save it).

"value": "Una falta de comprobaci\u00f3n de entrada en el archivo internal/db/repo_editor.go en Gogs versiones anteriores a 0.12.8, permite a un atacante ejecutar c\u00f3digo de forma remota. Un atacante no privilegiado (usuario registrado) puede sobrescribir la configuraci\u00f3n de Git en su repositorio. Esto conlleva a una Ejecuci\u00f3n de Comandos Remota, porque esa configuraci\u00f3n puede contener una opci\u00f3n como sshCommand, que es ejecutado cuando una rama maestra es una rama remota (usando una URI ssh://). La rama remota tambi\u00e9n puede configurarse al editar el archivo de configuraci\u00f3n de Git. Puede crearse un nuevo archivo en un nuevo repositorio, usando la interfaz gr\u00e1fica de usuario, con \"\\ ~\" como su nombre, y luego cambiar el nombre de este archivo a .git / configuraci\u00f3n con el contenido de la configuraci\u00f3n personalizada (y luego guardarlo)"
