critical Nessus Plugin ID 170927

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5839-1 advisory.

 It was discovered that the Apache HTTP Server mod_dav module incorrectly handled certain If: request headers. A remote attacker could possibly use this issue to cause the server to crash, resulting in a denial of service. (CVE-2006-20001)

 ZeddYu_Lu discovered that the Apache HTTP Server mod_proxy_ajp module incorrectly interpreted certain HTTP Requests. A remote attacker could possibly use this issue to perform an HTTP Request Smuggling attack.
 (CVE-2022-36760)

 Dimas Fariski Setyawan Putra discovered that the Apache HTTP Server mod_proxy module incorrectly truncated certain response headers. This may result in later headers not being interpreted by the client.
 (CVE-2022-37436)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
