CVE-2018-1121
3.9 · LOWOverview
CVE-2018-1121 is a low-severity vulnerability affecting procps_project procps. It was published on June 13, 2018 and has a CVSS 3.0 base score of 3.9 (LOW).
This vulnerability has a CVSS 3.0 base score of 3.9, rated LOW. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
procps-ng, procps is vulnerable to a process hiding through race condition. Since the kernel's proc_pid_readdir() returns PID entries in ascending numeric order, a process occupying a high PID can use inotify events to determine when the process list is being scanned, and fork/exec to obtain a lower PID, thus avoiding enumeration. An unprivileged attacker can hide a process from procps-ng's utilities by exploiting a race condition in reading /proc/PID entries. This vulnerability affects procps and procps-ng up to version 3.3.15, newer versions might be affected also.
Remediation
Check the references section for vendor advisories and patches from procps_project. Update procps to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
