Descriptions

Git before 2.10.5, 2.11.x before 2.11.4, 2.12.x before 2.12.5, 2.13.x before 2.13.6, and 2.14.x before 2.14.2 uses unsafe Perl scripts to support subcommands such as cvsserver, which allows attackers to execute arbitrary OS commands via shell metacharacters in a module name. The vulnerable code is reachable via git-shell even without CVS support.

Git en versiones anteriores a la 2.10.5, las versiones 2.11.x anteriores a 2.11.4, las 2.12.x anteriores a2.12.5, las 2.13.x anteriores a 2.13.6 y las 2.14.x anteriores a 2.14.2 emplean scripts de Perl no seguros para dar soporte a subcomandos como cvsserver. Esto permite que los atacantes ejecuten comandos arbitrarios del sistema operativo mediante metacaracteres shell en un nombre de módulo. El código vulnerable puede alcanzarse mediante git-shell incluso sin soporte para CVS.
