Apache HTTP Server
TMA-APACHE-3.13
Ensure Access to Special Purpose Application Writable Directories is Properly Restricted
Descripción
When the Apache webserver includes application software such as PHP, Java and many others, it is common for the application to require a writable directory. The writable directory may be needed for file uploads, application data, user session state information or many other purposes. It is important such directories have a single purpose, and have access properly secured to prevent a variety of possible exploits. Manual review: the benchmark gives no reliable automated check for this control.
Cómo se verifica
Método de auditoría: Revisión manual
Perform the following to determine if the recommended state is implemented: 1. Single Purpose Directory - For each application writable directory review the documented purpose for the directory to confirm the directory serves a single purpose. 2. Outside the Configured Web DocumentRoot - For each writable directory and it's corresponding DocumentRoot perform the following. No output from the find command indicates the directory is not within the DocumentRoot.
Cómo se corrige
Método de corrección: Guía o parche de infraestructura
Perform the following: 1. Single Purpose Directory - Create separate directories of the multipurpose directory, and adjust the application configuration and directory ownership and permissions appropriately. 2. Outside the Configured Web DocumentRoot - Move the writable directory to a more suitable location NOT under the DocumentRoot directory. A location within the /var/ filesystem may be a good choice for changeable data. 3. Owned by the root User or an Administrator Account - Change the ownership to root or an administrator. chown root $WR_DIR 4. Not writable by Other - Remove the other write permissions, use group write or ACLs to provide the least privileges necessary. chmod o-w $WR_DIR
