Descriptions

HylaFAX+ through 7.0.2 and HylaFAX Enterprise have scripts that execute binaries from directories writable by unprivileged users (e.g., locations under /var/spool/hylafax that are writable by the uucp account). This allows these users to execute code in the context of the user calling these binaries (often root).

HylaFAX+ versiones hasta 7.0.2 y HylaFAX Enterprise, presentan scripts que ejecutan archivos binarios desde directorios escritos por usuarios no privilegiados (por ejemplo, ubicaciones en /var/spool/hylafax que la cuenta uucp puede escribir). Esto permite a estos usuarios ejecutar código en el contexto del usuario llamando a estos binarios (a menudo root)
