Integer Overflow or Wraparound vulnerability in Apache ActiveMQ, Apache ActiveMQ All, Apache ActiveMQ MQTT. The fix for "CVE-2025-66168: MQTT control packet remaining length field is not properly validated" was only applied to 5.19.2 (and future 5.19.x) releases but was missed for all 6.0.0+ versions. This issue affects Apache ActiveMQ: from 6.0.0 before 6.2.4; Apache ActiveMQ All: from 6.0.0 before 6.2.4; Apache ActiveMQ MQTT: from 6.0.0 before 6.2.4. Users are recommended to upgrade to version 6.2.4 or a 5.19.x version starting with 5.19.2 or later (currently latest is 5.19.5), which fixes the issue.

The version of IBM Engineering Requirements Management DOORS (formerly IBM Rational DOORS) installed on the remote host is 9.6.1.1 prior or equal to 9.6.1.13 or 9.7.2.1 prior or equal to 9.7.2.11. It is, therefore, affected by multiple vulnerabilities as referenced in the 7279145 advisory.

  - IBM DOORS Web Access do not limit the length of a connection which could allow for a Slowloris HTTP denial     of service attack to take place. This can cause the web server to become unresponsive. (CVE-2024-25039)

  - IBM DOORS Web Access is vulnerable to cross-site scripting. This vulnerability allows an unauthenticated     attacker to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality     potentially leading to credentials disclosure within a trusted session. (CVE-2025-0152)

  - IBM DOORS Web Access could allow a remote attacker to obtain sensitive information when a detailed     technical error message is returned in the browser. This information could be used in further attacks     against the system. (CVE-2020-4984)

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