The remote SUSE Linux SLES15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:3335-1 advisory.

  - A crafted method sent through HTTP/2 will bypass validation and be forwarded by mod_proxy, which can lead     to request splitting or cache poisoning. This issue affects Apache HTTP Server 2.4.17 to 2.4.48.
    (CVE-2021-33193)

  - Malformed requests may cause the server to dereference a NULL pointer. This issue affects Apache HTTP     Server 2.4.48 and earlier. (CVE-2021-34798)

  - 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)

  - A crafted request uri-path can cause mod_proxy to forward the request to an origin server choosen by the     remote user. This issue affects Apache HTTP Server 2.4.48 and earlier. (CVE-2021-40438)

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