Ensure Group Write Access for the Document Root Directories and Files Is Properly Restricted
Description
The Apache Document Root directory $DOCROOT may need to be writeable by an authorized group such as development, support, or a production content management tool. However, it is important that the Apache group used to run the server does not have write access to any directories or files in the document root.
Rationale
Preventing Apache from writing to the web document root helps mitigate risk associated with web application vulnerabilities associated with file uploads or command execution. Typically, if an application hosted by Apache needs to write to a directory, it is best practice to have that directory live outside the web root.
Impact
None documented
Audit Procedure
Verify that there are no files or directories in the Apache Document Root directory with Apache group write access:
## Define $GRP to be the Apache group configured
# GRP=$(grep '^Group' $APACHE_PREFIX/conf/httpd.conf | cut -d' ' -f2)
# find -L $DOCROOT -group $GRP -perm /g=w -ls
Remediation
Perform the following to remove group write access on the $DOCROOT directories and files for the apache group:
# find -L $DOCROOT -group $GRP -perm /g=w -print | xargs chmod g-w
Default Value
None documented
