The optional ActiveMQ LDAP login module can be configured to use anonymous access to the LDAP server. In this case, for Apache ActiveMQ Artemis prior to version 2.16.0 and Apache ActiveMQ prior to versions 5.16.1 and 5.15.14, the anonymous context is used to verify a valid users password in error, resulting in no check on the password.

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6910-1 advisory.

    Chess Hazlett discovered that Apache ActiveMQ incorrectly handled certain commands. A remote attacker     could possibly use this issue to terminate the program, resulting in a denial of service. This issue only     affected Ubuntu 16.04 LTS. (CVE-2015-7559)

    Peter Stckli discovered that Apache ActiveMQ incorrectly handled hostname verification. A remote     attacker could possibly use this issue to perform a person-in-the-middle attack. This issue only affected     Ubuntu 16.04 LTS. (CVE-2018-11775)

    Jonathan Gallimore and Colm  higeartaigh discovered that Apache ActiveMQ incorrectly handled     authentication in certain functions. A remote attacker could possibly use this issue to perform a person-     in-the-middle attack. This issue only affected Ubuntu 16.04 LTS, Ubuntu 18.04 LTS and Ubuntu 20.04 LTS.
    (CVE-2020-13920)

    Gregor Tudan discovered that Apache ActiveMQ incorrectly handled LDAP authentication. A remote attacker     could possibly use this issue to acquire unauthenticated access. This issue only affected Ubuntu 16.04     LTS, Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. (CVE-2021-26117)

    It was discovered that Apache ActiveMQ incorrectly handled authentication. A remote attacker could     possibly use this issue to run arbitrary code. (CVE-2022-41678)

    It was discovered that Apache ActiveMQ incorrectly handled deserialization. A remote attacker could     possibly use this issue to run arbitrary shell commands. (CVE-2023-46604)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3657 advisory.

  - Apache ActiveMQ uses LocateRegistry.createRegistry() to create the JMX RMI registry and binds the server     to the jmxrmi entry. It is possible to connect to the registry without authentication and call the     rebind method to rebind jmxrmi to something else. If an attacker creates another server to proxy the     original, and bound that, he effectively becomes a man in the middle and is able to intercept the     credentials when an user connects. Upgrade to Apache ActiveMQ 5.15.12. (CVE-2020-13920)

  - The optional ActiveMQ LDAP login module can be configured to use anonymous access to the LDAP server. In     this case, for Apache ActiveMQ Artemis prior to version 2.16.0 and Apache ActiveMQ prior to versions     5.16.1 and 5.15.14, the anonymous context is used to verify a valid users password in error, resulting in     no check on the password. (CVE-2021-26117)

  - 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)

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

Multiple security issues were discovered in activemq, a message broker built around Java Message Service.

CVE-2017-15709

When using the OpenWire protocol in activemq, it was found that certain system details (such as the OS and kernel version) are exposed as plain text.

CVE-2018-11775

TLS hostname verification when using the Apache ActiveMQ Client was missing which could make the client vulnerable to a MITM attack between a Java application using the ActiveMQ client and the ActiveMQ server. This is now enabled by default.

CVE-2019-0222

Unmarshalling corrupt MQTT frame can lead to broker Out of Memory exception making it unresponsive

CVE-2021-26117

The optional ActiveMQ LDAP login module can be configured to use anonymous access to the LDAP server. The anonymous context is used to verify a valid users password in error, resulting in no check on the password.

For Debian 9 stretch, these problems have been fixed in version 5.14.3-3+deb9u2.

We recommend that you upgrade your activemq packages.

For the detailed security status of activemq please refer to its security tracker page at:

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The version of Apache ActiveMQ running on the remote host is 5.x prior to 5.15.14 or 5.16.x prior to 5.16.1. It is, therefore, affected by multiple vulnerabilities including the following: 

  - An authentication bypass vulnerability. The optional ActiveMQ LDAP login module can be configured   to use anonymous access to the LDAP server. In this case, for Apache ActiveMQ prior to versions 5.16.1 and   5.15.14, the anonymous context is used to verify a valid users password in error, resulting in no check on   the password. (CVE-2021-26117)

  - A cross-site scripting (XSS) vulnerability exists in Apache ActiveMQ due to improper validation of   user-supplied input before returning it to users. An unauthenticated, remote attacker can exploit this,   by convincing a user to click a specially crafted URL, to execute arbitrary script code in a user's browser   session. (CVE-2020-13947)

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