The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3117 advisory.

  - An issue was discovered in MediaWiki before 1.35.6, 1.36.x before 1.36.4, and 1.37.x before 1.37.2. Users     with the editinterface permission can trigger infinite recursion, because a bare local interwiki is     mishandled for the mainpage message. (CVE-2022-28201)

  - An XSS issue was discovered in MediaWiki before 1.35.6, 1.36.x before 1.36.4, and 1.37.x before 1.37.2.
    The widthheight, widthheightpage, and nbytes properties of messages are not escaped when used in galleries     or Special:RevisionDelete. (CVE-2022-28202)

  - A denial-of-service issue was discovered in MediaWiki before 1.35.6, 1.36.x before 1.36.4, and 1.37.x     before 1.37.2. When many files exist, requesting Special:NewFiles with actor as a condition can result in     a very long running query. (CVE-2022-28203)

  - An issue was discovered in MediaWiki before 1.35.7, 1.36.x and 1.37.x before 1.37.3, and 1.38.x before     1.38.1. XSS can occur in configurations that allow a JavaScript payload in a username. After account     creation, when it sets the page title to Welcome followed by the username, the username is not escaped:
    SpecialCreateAccount::successfulAction() calls ::showSuccessPage() with a message as second parameter, and     OutputPage::setPageTitle() uses text(). (CVE-2022-34911)

  - An issue was discovered in MediaWiki before 1.37.3 and 1.38.x before 1.38.1. The contributions-title, used     on Special:Contributions, is used as page title without escaping. Hence, in a non-default configuration     where a username contains HTML entities, it won't be escaped. (CVE-2022-34912)

  - Mediawiki reports: (T292763. CVE-2021-44854) REST API incorrectly publicly caches             autocomplete     search results from private wikis. (T271037, CVE-2021-44856) Title blocked in AbuseFilter can be created     via             Special:ChangeContentModel. (T297322, CVE-2021-44857) Unauthorized users can use     action=mcrundo to             replace the content of arbitrary pages.  (T297322, CVE-2021-44858)     Unauthorized users can view contents of private             wikis using various actions. (T297574,     CVE-2021-45038) Unauthorized users can access private wiki             contents using rollback action     (T293589, CVE-2021-44855) Blind Stored XSS in VisualEditor media dialog. (T294686) Special:Nuke doesn't     actually delete pages. (CVE-2021-44856)

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

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 79ea6066-b40e-11ec-8b93-080027b24e86 advisory.

  - An XSS issue was discovered in MediaWiki before 1.35.6, 1.36.x before 1.36.4, and 1.37.x before 1.37.2.
    The widthheight, widthheightpage, and nbytes properties of messages are not escaped when used in galleries     or Special:RevisionDelete. (CVE-2022-28202)

  - An issue was discovered in MediaWiki before 1.35.6, 1.36.x before 1.36.4, and 1.37.x before 1.37.2. Users     with the editinterface permission can trigger infinite recursion, because a bare local interwiki is     mishandled for the mainpage message. (CVE-2022-28201)

  - A denial-of-service issue was discovered in MediaWiki before 1.35.6, 1.36.x before 1.36.4, and 1.37.x     before 1.37.2. When many files exist, requesting Special:NewFiles with actor as a condition can result in     a very long running query. (CVE-2022-28203)

  - A denial-of-service issue was discovered in MediaWiki 1.37.x before 1.37.2. Rendering of     w/index.php?title=Special%3AWhatLinksHere&target=Property%3AP31&namespace=1&invert=1 can take more than     thirty seconds. There is a DDoS risk. (CVE-2022-28204)

  - Guzzle is a PHP HTTP client. Guzzle prior to versions 6.5.6 and 7.4.3 contains a vulnerability with the     cookie middleware. The vulnerability is that it is not checked if the cookie domain equals the domain of     the server which sets the cookie via the Set-Cookie header, allowing a malicious server to set cookies for     unrelated domains. The cookie middleware is disabled by default, so most library consumers will not be     affected by this issue. Only those who manually add the cookie middleware to the handler stack or     construct the client with ['cookies' => true] are affected. Moreover, those who do not use the same Guzzle     client to call multiple domains and have disabled redirect forwarding are not affected by this     vulnerability. Guzzle versions 6.5.6 and 7.4.3 contain a patch for this issue. As a workaround, turn off     the cookie middleware. (CVE-2022-29248)

  - Guzzle is an open source PHP HTTP client. In affected versions the `Cookie` headers on requests are     sensitive information. On making a request using the `https` scheme to a server which responds with a     redirect to a URI with the `http` scheme, or on making a request to a server which responds with a     redirect to a a URI to a different host, we should not forward the `Cookie` header on. Prior to this fix,     only cookies that were managed by our cookie middleware would be safely removed, and any `Cookie` header     manually added to the initial request would not be stripped. We now always strip it, and allow the cookie     middleware to re-add any cookies that it deems should be there. Affected Guzzle 7 users should upgrade to     Guzzle 7.4.4 as soon as possible. Affected users using any earlier series of Guzzle should upgrade to     Guzzle 6.5.7 or 7.4.4. Users unable to upgrade may consider an alternative approach to use your own     redirect middleware, rather than ours. If you do not require or expect redirects to be followed, one     should simply disable redirects all together. (CVE-2022-31042)

  - Guzzle is an open source PHP HTTP client. In affected versions `Authorization` headers on requests are     sensitive information. On making a request using the `https` scheme to a server which responds with a     redirect to a URI with the `http` scheme, we should not forward the `Authorization` header on. This is     much the same as to how we don't forward on the header if the host changes. Prior to this fix, `https` to     `http` downgrades did not result in the `Authorization` header being removed, only changes to the host.
    Affected Guzzle 7 users should upgrade to Guzzle 7.4.4 as soon as possible. Affected users using any     earlier series of Guzzle should upgrade to Guzzle 6.5.7 or 7.4.4. Users unable to upgrade may consider an     alternative approach which would be to use their own redirect middleware. Alternately users may simply     disable redirects all together if redirects are not expected or required. (CVE-2022-31043)

  - Guzzle, an extensible PHP HTTP client. `Authorization` headers on requests are sensitive information. In     affected versions when using our Curl handler, it is possible to use the `CURLOPT_HTTPAUTH` option to     specify an `Authorization` header. On making a request which responds with a redirect to a URI with a     different origin (change in host, scheme or port), if we choose to follow it, we should remove the     `CURLOPT_HTTPAUTH` option before continuing, stopping curl from appending the `Authorization` header to     the new request. Affected Guzzle 7 users should upgrade to Guzzle 7.4.5 as soon as possible. Affected     users using any earlier series of Guzzle should upgrade to Guzzle 6.5.8 or 7.4.5. Note that a partial fix     was implemented in Guzzle 7.4.2, where a change in host would trigger removal of the curl-added     Authorization header, however this earlier fix did not cover change in scheme or change in port. If you do     not require or expect redirects to be followed, one should simply disable redirects all together.
    Alternatively, one can specify to use the Guzzle steam handler backend, rather than curl. (CVE-2022-31090)

  - Guzzle, an extensible PHP HTTP client. `Authorization` and `Cookie` headers on requests are sensitive     information. In affected versions on making a request which responds with a redirect to a URI with a     different port, if we choose to follow it, we should remove the `Authorization` and `Cookie` headers from     the request, before containing. Previously, we would only consider a change in host or scheme. Affected     Guzzle 7 users should upgrade to Guzzle 7.4.5 as soon as possible. Affected users using any earlier series     of Guzzle should upgrade to Guzzle 6.5.8 or 7.4.5. Note that a partial fix was implemented in Guzzle     7.4.2, where a change in host would trigger removal of the curl-added Authorization header, however this     earlier fix did not cover change in scheme or change in port. An alternative approach would be to use your     own redirect middleware, rather than ours, if you are unable to upgrade. If you do not require or expect     redirects to be followed, one should simply disable redirects all together. (CVE-2022-31091)
