EulerOS 2.0 SP9 : haproxy (EulerOS-SA-2023-1870)

critical Nessus Plugin ID 175516

Synopsis

The remote EulerOS host is missing a security update.

Description

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

 - HAProxy before 2.7.3 may allow a bypass of access control because HTTP/1 headers are inadvertently lost in some situations, aka 'request smuggling.' The HTTP header parsers in HAProxy may accept empty header field names, which could be used to truncate the list of HTTP headers and thus make some headers disappear after being parsed and processed for HTTP/1.0 and HTTP/1.1. For HTTP/2 and HTTP/3, the impact is limited because the headers disappear before being parsed and processed, as if they had not been sent by the client. The fixed versions are 2.7.3, 2.6.9, 2.5.12, 2.4.22, 2.2.29, and 2.0.31. (CVE-2023-25725)

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.
