FKIE_CVE-2020-1930
Vulnerability from fkie_nvd - Published: 2020-01-30 18:15 - Updated: 2024-11-21 05:11
Severity ?
Summary
A command execution issue was found in Apache SpamAssassin prior to 3.4.3. Carefully crafted nefarious rule configuration (.cf) files can be configured to run system commands similar to CVE-2018-11805. With this bug unpatched, exploits can be injected in a number of scenarios including the same privileges as spamd is run which may be elevated 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. If you cannot upgrade, do not use 3rd party rulesets, do not use sa-compile and do not run spamd as an account with elevated privileges.

"value": "Se detect\u00f3 un problema de ejecuci\u00f3n de comando en Apache SpamAssassin versiones anteriores a 3.4.3. Los archivos (.cf) de Configuraci\u00f3n de reglas nefastas cuidadosamente dise\u00f1adas pueden ser configuradas para ejecutar comandos de sistema similar al CVE-2018-11805. Con este error sin parchear, pueden ser inyectadas las explotaciones en varios escenarios, incluyendo los mismos privilegios en que se ejecuta spamd, que pueden ser elevados, aunque hacerlo remotamente es dif\u00edcil. Adem\u00e1s de actualizar a SA versi\u00f3n 3.4.4, recomendamos de nuevo que los usuarios solo deben usar canales de actualizaci\u00f3n o archivos .cf de terceros desde lugares confiables. Si no puede actualizar, no use conjuntos de reglas de terceros, no use sa-compile y no ejecute spamd como una cuenta con privilegios elevados."
