The remote Red Hat Enterprise Linux CoreOS  host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:5208 advisory.

  - haproxy: does not ensure that the scheme and path portions of a URI have the expected characters     (CVE-2021-39240)

  - haproxy: an HTTP method name may contain a space followed by the name of a protected resource     (CVE-2021-39241)

  - haproxy: 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)

The version of haproxy2 installed on the remote host is prior to 2.2.17-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2HAPROXY2-2023-005 advisory.

    A flaw was found in haproxy. An input validation flaw when processing HTTP/2 requests causes haproxy to     not ensure that the scheme and path portions of a URI have the expected characters.  This may cause     specially crafted input to bypass implemented security restrictions. The highest threat from this     vulnerability is confidentiality. (CVE-2021-39240)

    haproxy has an input validation flaw that could allow a remote attacker to bypass implemented security     restrictions.  An HTTP method name may contain a space followed by the name of a protected resource. Given     this, It is possible that an server would interpret this as a request for that protected resource. The     highest threat from this vulnerability is possible confidentiality concerns. (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)

    Proxy server haproxy has a flaw that can could allow an HTTP request smuggling attack with the goal of     bypassing access-control list rules defined by haproxy. The attack was made possible by utilizing an     integer overflow vulnerability that allowed reaching an unexpected state in haproxy while parsing an HTTP     request. The highest threat from this vulnerability is integrity. (CVE-2021-40346)
