A vital vulnerability in Apache ActiveMQ, recognized as CVE-2023-46604, has been uncovered, revealing an lively exploitation situation by the infamous Kinsing malware.
In accordance with an advisory revealed by Pattern Micro on Monday, the invention underscores the implications for Linux programs, because the vulnerability permits for distant code execution (RCE) as a result of insufficient validation of throwable class sorts in OpenWire instructions.
Apache ActiveMQ, a Java-based open supply protocol, is broadly used for message-oriented middleware, facilitating seamless communication between numerous functions.
Kinsing, a potent menace particularly focusing on Linux-based programs, capitalizes on net utility vulnerabilities and misconfigured container environments to infiltrate servers and swiftly propagate throughout networks.
Stories of lively exploitation of CVE-2023-46604 surfaced in November, with menace actors using exploits comparable to Metasploit and Nuclei. Regardless of the severity of the vulnerability (CVSS 9.8), detection stays comparatively low.
“The hazard with this CVE is that Apache ActiveMQ is broadly used, and since it will possibly talk throughout a number of protocols (comparable to MQTT), additionally it is broadly utilized in non-IT environments to interface to IoT/OT/ICS units,” defined John Gallagher, vice chairman of Viakoo Labs at Viakoo.
“Many IoT units have highly effective processing capabilities and lack patching insurance policies, making [crypto]mining a great exercise for them.”
The Kinsing exploit makes use of the ProcessBuilder technique, resulting in the obtain and execution of cryptocurrency miners and malware on compromised programs. Notably, the malware actively seeks and eliminates competing cryptocurrency miners.
The menace actors orchestrating Kinsing exploit not solely CVE-2023-46604 but additionally different high-profile vulnerabilities like CVE-2023-4911 (Looney Tunables).

Trend Micro urged customers to promptly improve to mitigate the dangers related to this vulnerability. The patch for CVE-2023-46604 addresses the foundation trigger by introducing the “validateIsThrowable” technique within the “BaseDataStreamMarshall” class.
“To protect in opposition to this [threat], organizations ought to prioritize patching and remediation, particularly for all external-facing publicity and people with higher-value belongings,” mentioned Ken Dunham, director of cyber menace at Qualys.
“Moreover, precautions comparable to in depth monitoring and logging opinions with workarounds the place they apply are really useful to counter identified TTPs for brute-force and identified assaults till the danger of exploitation is totally remediated.”
