EulerOS 2.0 SP9 : haproxy (EulerOS-SA-2021-2687)

high Nessus Plugin ID 155237

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

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

 - An issue was discovered in HAProxy 2.0 before 2.0.24, 2.2 before 2.2.16, 2.3 before 2.3.13, and 2.4 before 2.4.3. An HTTP method name may contain a space followed by the name of a protected resource. It is possible that a server would interpret this as a request for that protected resource, such as in the 'GET /admin? HTTP/1.1 /static/images HTTP/1.1' example. (CVE-2021-39241)

 - An issue was discovered in HAProxy 2.2 before 2.2.16, 2.3 before 2.3.13, and 2.4 before 2.4.3. It can lead to a situation with an attacker-controlled HTTP Host header, because a mismatch between Host and authority is mishandled. (CVE-2021-39242)

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 haproxy packages.
