CVE-2018-6693 is a medium-severity vulnerability rated 5.3/10 on the CVSS scale. An unprivileged user can delete arbitrary files on a Linux system running ENSLTP 10.5.1, 10.5.0, and 10.2.3 Hotfix 1246778 and earlier. By exploiting a time of check to time of use (TOCTOU) race condition during a specific scanning sequence, the unprivileged user is able to perform a privilege escalation to delete arbitrary files.. EPSS estimates a 0.18% chance of exploitation in the next 30 days.
