Synopsis
The remote Red Hat host is missing one or more security updates for Red Hat JBoss Core Services Apache HTTP Server 2.4.51.Description
The remote Redhat Enterprise Linux 7 / 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2022:7143 advisory.- httpd: Request splitting via HTTP/2 method injection and mod_proxy (CVE-2021-33193)
- A carefully crafted request uri-path can cause mod_proxy_uwsgi to read above the allocated memory and crash (DoS). This issue affects Apache HTTP Server versions 2.4.30 to 2.4.48 (inclusive). (CVE-2021-36160)
- ap_escape_quotes() may write beyond the end of a buffer when given malicious input. No included modules pass untrusted data to these functions, but third-party / external modules may. This issue affects Apache HTTP Server 2.4.48 and earlier. (CVE-2021-39275)
- httpd: NULL pointer dereference via crafted request during HTTP/2 request processing (CVE-2021-41524)
- A crafted URI sent to httpd configured as a forward proxy (ProxyRequests on) can cause a crash (NULL pointer dereference) or, for configurations mixing forward and reverse proxy declarations, can allow for requests to be directed to a declared Unix Domain Socket endpoint (Server Side Request Forgery). This issue affects Apache HTTP Server 2.4.7 up to 2.4.51 (included). (CVE-2021-44224)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
