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 IBM Engineering Requirements Management DOORS (formerly IBM Rational DOORS) installed on the remote host is 9.7.2.9 prior to 9.7.2.10. It is, therefore, affected by multiple vulnerabilities as referenced in the 7238992 advisory.

  - CKEditor4 is an open source WYSIWYG HTML editor. In affected version a vulnerability has been discovered in the     core HTML processing module and may affect all plugins used by CKEditor 4. The vulnerability allowed to inject     malformed comments HTML bypassing content sanitization, which could result in executing JavaScript code. It     affects all users using the CKEditor 4 at version < 4.17.0. The problem has been recognized and patched. The     fix will be available in version 4.17.0. (CVE-2021-41165)

  - CKEditor4 is an open source WYSIWYG HTML editor. In affected versions a vulnerability has been discovered in the     Advanced Content Filter (ACF) module and may affect all plugins used by CKEditor 4. The vulnerability allowed to     inject malformed HTML bypassing content sanitization, which could result in executing JavaScript code. It affects     all users using the CKEditor 4 at version < 4.17.0. The problem has been recognized and patched. The fix will be     available in version 4.17.0. (CVE-2021-41164)

  - It was possible to execute a ReDoS-type attack inside CKEditor 4 before 4.16 by persuading a victim to paste crafted     text into the Styles input of specific dialogs (in the Advanced Tab for Dialogs plugin). (CVE-2021-26271)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - A cross-site scripting (XSS) vulnerability in the HTML Data Processor in CKEditor 4 4.14.0 through 4.16.x     before 4.16.1 allows remote attackers to inject executable JavaScript code through a crafted comment     because --!> is mishandled. (CVE-2021-33829)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Debian 9 host has a package installed that is affected by multiple vulnerabilities as referenced in the dla-2813 advisory.

    CKEditor, an open source WYSIWYG HTML editor with rich content support, which can be embedded into web     pages, had two vulnerabilites as follows: CVE-2021-33829 A cross-site scripting (XSS) vulnerability in the     HTML Data Processor in CKEditor 4 allows remote attackers to inject executable JavaScript code through a     crafted comment because --!> is mishandled. CVE-2021-37695 A potential vulnerability has been discovered     in CKEditor 4 Fake Objects package. The vulnerability allowed to inject malformed Fake Objects HTML, which     could result in executing JavaScript code. For Debian 9 stretch, these problems have been fixed in version     4.5.7+dfsg-2+deb9u1. We recommend that you upgrade your ckeditor packages. For the detailed security     status of ckeditor please refer to its security tracker page at: https://security-     tracker.debian.org/tracker/ckeditor Further information about Debian LTS security advisories, how to apply     these updates to your system and frequently asked questions can be found at: https://wiki.debian.org/LTS

The version of IBM Engineering Requirements Management DOORS (formerly IBM Rational DOORS) installed on the remote host is 9.7.2.x prior to 9.7.2.8. It is, therefore, affected by multiple vulnerabilities as referenced in the 7124058 advisory.

  - Apache Shiro before 1.9.1, A RegexRequestMatcher can be misconfigured to be bypassed on some servlet     containers. Applications using RegExPatternMatcher with `.` in the regular expression are possibly     vulnerable to an authorization bypass. (CVE-2022-32532)

  - The Java OpenWire protocol marshaller is vulnerable to Remote Code Execution. This vulnerability may allow     a remote attacker with network access to either a Java-based OpenWire broker or client to run arbitrary     shell commands by manipulating serialized class types in the OpenWire protocol to cause either the client     or the broker (respectively) to instantiate any class on the classpath. Users are recommended to upgrade     both brokers and clients to version 5.15.16, 5.16.7, 5.17.6, or 5.18.3 which fixes this issue.
    (CVE-2023-46604)

  - Scala 2.13.x before 2.13.9 has a Java deserialization chain in its JAR file. On its own, it cannot be     exploited. There is only a risk in conjunction with Java object deserialization within an application. In     such situations, it allows attackers to erase contents of arbitrary files, make network connections, or     possibly run arbitrary code (specifically, Function0 functions) via a gadget chain. (CVE-2022-36944)

  - IBM Engineering Requirements Management DOORS 9.7.2.7 is vulnerable to cross-site request forgery which     could allow an attacker to execute malicious and unauthorized actions transmitted from a user that the     website trusts. IBM X-Force ID: 251216. (CVE-2023-28949)

  - A cross-site scripting (XSS) vulnerability in the HTML Data Processor for CKEditor 4.0 before 4.14 allows     remote attackers to inject arbitrary web script through a crafted protected comment (with the     cke_protected syntax). (CVE-2020-9281)
