The version of Firefox installed on the remote Windows host is prior to 72.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2020-01 advisory, including the following:

  - During the initialization of a new content process, a pointer offset can be manipulated leading to     memory corruption and a potentially exploitable crash in the parent process. (CVE-2019-17015)

  - When pasting a <style> tag from the clipboard into a rich text editor, the CSS sanitizer incorrectly     rewrites a @namespace rule. This could allow for injection into certain types of websites resulting in     data exfiltration. (CVE-2019-17016)

  - Due to a missing case handling object types, a type confusion vulnerability could occur, resulting in a     crash. We presume that with enough effort that it could be exploited to run arbitrary code.
    (CVE-2019-17017)

  - When in Private Browsing Mode on Windows 10, the Windows keyboard may retain word suggestions to improve     the accuracy of the keyboard. (CVE-2019-17018)

  - When Python was installed on Windows, a python file being served with the MIME type of text/plain could     be executed by Python instead of being opened as a text file when the Open option was selected upon     download. (CVE-2019-17019)

  - If an XML file is served with a Content Security Policy and the XML file includes an XSL stylesheet, the     Content Security Policy will not be applied to the contents of the XSL stylesheet. If the XSL sheet e.g.
    includes JavaScript, it would bypass any of the restrictions of the Content Security Policy applied to     the XML document. (CVE-2019-17020)

  - During the initialization of a new content process, a race condition occurs that can allow a content     process to disclose heap addresses from the parent process. (CVE-2019-17021)

  - When pasting a <style> tag from the clipboard into a rich text editor, the CSS sanitizer does not escape     < and > characters. Because the resulting string is pasted directly into the text node of the element     this does not result in a direct injection into the webpage; however, if a webpage subsequently copies     the node's innerHTML, assigning it to another innerHTML, this would result in an XSS vulnerability. Two     WYSIWYG editors were identified with this behavior, more may exist. (CVE-2019-17022)     
  - After a HelloRetryRequest has been sent, the client may negotiate a lower protocol that TLS 1.3,     resulting in an invalid state transition in the TLS State Machine. If the client gets into this state,     incoming Application Data records will be ignored. (CVE-2019-17023)

  - Mozilla developers Jason Kratzer, Christian Holler, and Bob Clary reported memory safety bugs present in     Firefox 71 and Firefox ESR 68.3. Some of these bugs showed evidence of memory corruption and we presume     that with enough effort some of these could have been exploited to run arbitrary code. (CVE-2019-17024)

  - Mozilla developers Karl Tomlinson, Jason Kratzer, Tyson Smith, Jon Coppeard, and Christian Holler     reported memory safety bugs present in Firefox 71. Some of these bugs showed evidence of memory     corruption and we presume that with enough effort some of these could have been exploited to run     arbitrary code. (CVE-2019-17025)

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

リモートの Windows ホストにインストールされている Firefox のバージョンは、72.0より前です。It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2020-01 advisory, including the following:

  - During the initialization of a new content process, a pointer offset can be manipulated leading to memory corruption and a potentially exploitable crash in the parent process. (CVE-2019-17015)

  - <style> タグをクリップボードからリッチテキストエディターに貼り付ける際に、CSS サニタイザーが不適切に @namespace ルールを書き換えます。 This could allow for injection into certain types of websites resulting in data exfiltration. (CVE-2019-17016)

  - オブジェクトタイプのケース処理が欠落しているため、型の取り違え (Type Confusion) の脆弱性が発生し、クラッシュが引き起こされます。十分な労力をもってすれば、これを悪用し、任意のコードを実行することが可能と考えられます。
    (CVE-2019-17017)

  - When in Private Browsing Mode on Windows 10, the Windows keyboard may retain word suggestions to improve the accuracy of the keyboard. (CVE-2019-17018)

  - When Python was installed on Windows, a python file being served with the MIME type of text/plain could be executed by Python instead of being opened as a text file when the Open option was selected upon download. (CVE-2019-17019)

  - During the initialization of a new content process, a race condition occurs that can allow a content process to disclose heap addresses from the parent process. (CVE-2019-17021)

  - <style> タグをクリップボードからリッチテキストエディターに貼り付ける際に、CSS サニタイザーが < and > 文字をエスケープしません。 結果の文字列は要素のテキストノードに直接貼り付けられるため、これはWebページへの直接注入にはなりません。ただし、その後 Web ページがノードの innerHTML をコピーして別の innerHTML に割り当てると、XSS の脆弱性が発生します。Two WYSIWYG editors were identified with this behavior, more may exist. (CVE-2019-17022)     
  - HelloRetryRequest の送信後、クライアントが TLS 1.3 より低いプロトコルをネゴシエートして、TLS の状態マシンで無効な状態移行を引き起こす可能性があります。If the client gets into this state, incoming Application Data records will be ignored. (CVE-2019-17023)

  - Mozilla developers Jason Kratzer, Christian Holler, and Bob Clary reported memory safety bugs present in Firefox 71 and Firefox ESR 68.3. これらのバグの一部にはメモリ破損の証拠が示されており、当社では、十分な労力をもってすればこれらの一部を悪用し、任意のコードを実行することが可能であると推測しています。(CVE-2019-17024)

Nessusはこの問題をテストしておらず、代わりにアプリケーションの自己報告されたバージョン番号にのみ依存しています。
