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 the tmp directory, which is accessible by /lam/tmp/, allows interpretation of .php (and .php5/.php4/.phpt/etc) files. An attacker capable of writing files under www-data privileges can write a web-shell into this directory, and gain a Code Execution on the host. This issue has been fixed in version 8.0. Users unable to upgrade should disallow executing PHP scripts in (/var/lib/ldap-account-manager/)tmp directory.

En versiones anteriores a 8.0, el directorio tmp, al que se accede mediante /lam/tmp/, permite interpretar los archivos .php (y .php5/.php4/.phpt/etc). Un atacante capaz de escribir archivos bajo los privilegios de www-data puede escribir un web-shell en este directorio, y obtener una Ejecución de Código en el host. Este problema ha sido corregido en versión 8.0. Los usuarios que no puedan actualizarse deben deshabilitar la ejecución de scripts PHP en el directorio (/var/lib/ldap-account-manager/)tmp
