OS version: RHEL 8

Iam new to checkmk and linux

Can any one help me with the tenable vulnerability

DNS Name: XXXXXXXXX01.XXX.XXX.net
NetBIOS Name:
Plugin Output:
Version source : Server: Apache/2.4.37 (Red Hat Enterprise Linux) OpenSSL/1.1.1k
Installed version : 2.4.37
Synopsis: The remote Apache server is vulnerable to multiple privilege escalation attacks.
Description: The remote host appears to be running Apache and is potentially affected by the following vulnerabilities:

  • Multiple race conditions exist in suexec between the validation and usage of directories and files. Under certain conditions local users are able to
    escalate privileges and execute arbitrary code through the renaming of directories or symlink attacks.
    (CVE-2007-1741)
  • Apache’s suexec module only performs partial comparisons on paths, which could result in privilege escalation. (CVE-2007-1742)
  • Apache’s suexec module does not properly verify user and group IDs on the command line. When the ‘/proc’ filesystem is mounted, a local user can
    utilize suexec to escalate privileges. (CVE-2007-1743)
    Note that this plugin only checks for the presence of Apache, and does not actually check the configuration.

Steps to Remediate: Disable suexec or disallow users from writing to the document root.

This message refers to your OS (RHEL 8).
You need to check if the installed RHEL package is affected by the mentioned CVE’s.
CheckMK by itself has no build-in Apache. It uses the system installed one.
