Descriptions

A command execution issue was found in Apache SpamAssassin prior to 3.4.3. Carefully crafted nefarious Configuration (.cf) files can be configured to run system commands similar to CVE-2018-11805. This issue is less stealthy and attempts to exploit the issue will throw warnings. Thanks to Damian Lukowski at credativ for reporting the issue ethically. With this bug unpatched, exploits can be injected in a number of scenarios though doing so remotely is difficult. In addition to upgrading to SA 3.4.4, we again recommend that users should only use update channels or 3rd party .cf files from trusted places.

Se detectó un problema de ejecución de comando en Apache SpamAssassin versiones anteriores a 3.4.3. Los archivos (.cf) de Configuración nefastos cuidadosamente diseñados pueden ser configurados para ejecutar comandos de sistema similar al CVE-2018-11805. Este problema es menos sigiloso y los intentos para explotarlo arrojarán advertencias. Gracias a Damian Lukowski en credativ por reportar el problema éticamente. Con este error sin parchear, pueden ser inyectadas explotaciones en varios escenarios, aunque hacerlo remotamente es difícil. Además de actualizar a SA versiones 3.4.4, recomendamos de nuevo que los usuarios solo deben usar canales de actualización o archivos .cf de terceros desde lugares confiables.
