Descriptions

LDAP Account Manager (LAM) is a webfrontend for managing entries (e.g. users, groups, DHCP settings) stored in an LDAP directory. In versions prior to 8.0 incorrect regular expressions allow to upload PHP scripts to config/templates/pdf. This vulnerability could lead to a Remote Code Execution if the /config/templates/pdf/ directory is accessible for remote users. This is not a default configuration of LAM. This issue has been fixed in version 8.0. There are no known workarounds for this issue.

LDAP Account Manager (LAM) es una interfaz web para administrar entradas (por ejemplo, usuarios, grupos, configuraciones DHCP) almacenadas en un directorio LDAP. En versiones anteriores a 8.0, expresiones regulares incorrectas permiten cargar scripts PHP en config/templates/pdf. Esta vulnerabilidad podría conllevar a una Ejecución de Código Remota si el directorio /config/templates/pdf/ es accesible para usuarios remotos. Esta no es una configuración por defecto de LAM. Este problema ha sido corregido en versión 8.0. No se presentan mitigaciones conocidas para este problema
