EulerOS 2.0 SP5 : mod_security (EulerOS-SA-2023-2160)

high Nessus Plugin ID 176993

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the mod_security package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

- In ModSecurity before 2.9.6 and 3.x before 3.0.8, HTTP multipart requests were incorrectly parsed and could bypass the Web Application Firewall. NOTE: this is related to CVE-2022-39956 but can be considered independent changes to the ModSecurity (C language) codebase. (CVE-2022-48279)

- Incorrect handling of '\0' bytes in file uploads in ModSecurity before 2.9.7 may allow for Web Application Firewall bypasses and buffer over-reads on the Web Application Firewall when executing rules that read the FILES_TMP_CONTENT collection. (CVE-2023-24021)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected mod_security packages.
