Descriptions

SuiteCRM before 7.11.19 allows remote code execution via the system settings Log File Name setting. In certain circumstances involving admin account takeover, logger_file_name can refer to an attacker-controlled PHP file under the web root, because only the all-lowercase PHP file extensions were blocked. NOTE: this issue exists because of an incomplete fix for CVE-2020-28328.

SuiteCRM versiones anteriores a 7.11.19, permite una ejecución de código remota por medio de la configuración del sistema Log File Name. En determinadas circunstancias que implican la toma de posesión de la cuenta de administrador, logger_file_name puede referirse a un archivo PHP controlado por el atacante bajo el root de la web, porque sólo las extensiones de archivos PHP en minúsculas fueron bloqueadas. NOTA: este problema se presenta debido a una corrección incompleta de CVE-2020-28328
