According to the versions of the httpd packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :
HTTP Response splitting in multiple modules in Apache HTTP Server allows an attacker that can inject malicious response headers into backend applications to cause an HTTP desynchronization attack.Users are recommended to upgrade to version 2.4.59, which fixes this issue.(CVE-2024-24795)
Faulty input validation in the core of Apache allows malicious or exploitable backend/content generators to split HTTP responses.This issue affects Apache HTTP Server: through 2.4.58.(CVE-2023-38709)
HTTP/2 incoming headers exceeding the limit are temporarily buffered in nghttp2 in order to generate an informative HTTP 413 response. If a client does not stop sending headers, this leads to memory exhaustion.(CVE-2024-27316)
Tenable has extracted the preceding description block directly from the EulerOS Virtualization httpd security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
