Description
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to insecure permissions on the " /var/lib/nfs" directory owned by statd:nogroup in the nfs-utils package in SUSE Linux Enterprise Server 12 before and including version 1.3.0-34.18.1 and in SUSE Linux Enterprise Server 15 before and including version 2.1.1-6.10.2. This directory contains files owned and managed by root. If statd is compromised, it can therefore trick processes running with root privileges into creating/overwriting files anywhere on the system.
Successful exploitation of the vulnerability may allow a local user to escalate privileges on the system.
Remediation
