Name of the Vulnerable Software and Affected Versions nfs-utils (affected versions not specified)

Description A flaw exists in the rpc.mountd daemon within the nfs-utils package for Linux. This issue allows a Network File System version 3 (NFSv3) client to gain higher privileges than those defined in the /etc/exports file during the mount process. Specifically, a client can access any subdirectory or subtree of an exported directory, bypassing standard file permissions and expected security attributes like 'root squash' or 'all squash'.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
