Apache server v2.4.58 - suexec issue

Good day dears,

Recently we have installed Apache server v2.4.58 in our CentOS 9, when make vulnerability scan with Nessus on the server the Nessus shows this vulnerability:

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.

So we need your support to disable suexec in the server.

Thanks,


Best regards

Hi,

looking at theses CVE, they all include "the vendor disputes the issue
because "the attacks described rely on an insecure server configuration"
in which the user "has write access to the document root.""

So considering them as security issues is up to you.

Disabling a module in Apache looks like a really basic task.
(just comment the corresponding line in the conf file)

2.4.59 was released a few days ago to address these...
