Vulnerability discussion

The executable search path (typically the PATH environment variable) contains a list of directories for the shell to search to find executables. If this path includes the current working directory or other relative paths, executables in these directories may be executed instead of system commands. This variable is formatted as a colon-separated list of directories. If there is an empty entry, such as a leading or trailing colon or two consecutive colons, this is interpreted as the current working directory. Entries starting with a slash (/) are absolute paths.

Check content

To view the root user's PATH, log in as the root user, and execute: # env | grep PATH OR # echo $PATH This variable is formatted as a colon-separated list of directories. If there is an empty entry, such as a leading or trailing colon, or two consecutive colons, this is a finding. If an entry starts with a character other than a slash (/), this is a finding. If directories beyond those in the vendor's default root path are present. This is a finding.

Fix text

Edit the root user's local initialization files ~/.profile,~/.bashrc (assuming root shell is bash). Change any found PATH variable settings to the vendor's default path for the root user. Remove any empty path entries or references to relative paths.
