"According to its self-reported version number, Zimbra Collaboration Server is affected by a multiple vulnerabilities,
including the following:

  - A vulnerability that allows an unauthenticated attacker to inject arbitrary memcache commands into a
    targeted instance. These memcache commands becomes unescaped, causing an overwrite of arbitrary cached
    entries. (CVE-2022-27924)

  - Zimbra Collaboration (aka ZCS) 8.8.15 and 9.0 has mboximport functionality that receives a ZIP archive and
    extracts files from it. An authenticated user with administrator rights has the ability to upload
    arbitrary files to the system, leading to directory traversal. (CVE-2022-27925)

  - 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)

  - 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)

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