There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - WARNING: Users of 6.x should upgrade to 6.2.4 or later as the fix was missed in previous 6.x releases. See
    the following for more details: https://activemq.apache.org/security-
    advisories.data/CVE-2026-40046-announcement.txt https://www.cve.org/CVERecord?id=CVE-2026-40046 Original
    Report: Apache ActiveMQ does not properly validate the remaining length field which may lead to an
    overflow during the decoding of malformed packets. When this integer overflow occurs, ActiveMQ may
    incorrectly compute the total Remaining Length and subsequently misinterpret the payload as multiple MQTT
    control packets which makes the broker susceptible to unexpected behavior when interacting with non-
    compliant clients. This behavior violates the MQTT v3.1.1 specification, which restricts Remaining Length
    to a maximum of 4 bytes. The scenario occurs on established connections after the authentication process.
    Brokers that are not enabling mqtt transport connectors are not impacted. This issue affects Apache
    ActiveMQ: before 5.19.2, 6.0.0 to 6.1.8, and 6.2.0 Users are recommended to upgrade to version 5.19.2,
    6.1.9, or 6.2.1, which fixes the issue. (CVE-2025-66168)

The version of Apache ActiveMQ running on the remote host is prior to 5.19.2, 6.0.x prior to 6.1.9, or 6.2.0. It is, therefore, affected by a vulnerability:

  - Apache ActiveMQ does not properly validate the remaining length field in MQTT control packets which may     lead to an integer overflow during the decoding of malformed packets. When this integer overflow occurs,     ActiveMQ may incorrectly compute the total Remaining Length and subsequently misinterpret the payload as     multiple MQTT control packets which makes the broker susceptible to unexpected behavior when interacting     with non-compliant clients. This behavior violates the MQTT v3.1.1 specification, which restricts     Remaining Length to a maximum of 4 bytes. The scenario occurs on established connections after the     authentication process. Brokers that are not enabling mqtt transport connectors are not impacted.
    (CVE-2025-66168)

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

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

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

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.
