CVE-2020-36868

Nagios XI versions prior to 5.7.3 contain a privilege escalation vulnerability in the getprofile.sh helper script. The script performed profile retrieval and initialization routines using insecure file/command handling and insufficient validation of attacker-controlled inputs, and in some deployments executed with elevated privileges. A local attacker with low-level access could exploit these weaknesses to cause the script to execute arbitrary commands or modify privileged files, resulting in privilege escalation.

Summary		(es) Las versiones de Nagios XI anteriores a la 5.7.3 contienen una vulnerabilidad de escalada de privilegios en el script auxiliar getprofile.sh. El script realizaba rutinas de recuperación e inicialización de perfiles utilizando un manejo inseguro de archivos/comandos y una validación insuficiente de las entradas controladas por el atacante, y en algunas implementaciones se ejecutaba con privilegios elevados. Un atacante local con acceso de bajo nivel podría explotar estas debilidades para hacer que el script ejecute comandos arbitrarios o modifique archivos privilegiados, lo que resultaría en una escalada de privilegios.
