Overview
The Common Vulnerabilities and Exposures (CVE) system has identified a significant vulnerability, CVE-2025-36014, in the IBM Integration Bus for z/OS versions 10.1.0.0 to 10.1.0.5. This vulnerability is critical as it allows a privileged user to inject malicious code into the system, posing serious risks to data integrity, confidentiality, and system stability.
As a code injection flaw, this vulnerability exploits the trust placed in user input to execute arbitrary commands, potentially compromising the entire system or leading to data leakage. Given the severity of the potential impact, it is crucial for all IBM Integration Bus users to understand and address this vulnerability.

How the Exploit Works
The exploit works by a privileged user injecting malicious code into the IBM Integration Bus for z/OS system. Due to improper validation of user input in the install directory, the system processes the injected code as legitimate commands.
This lapse in input validation gives the attacker the opportunity to manipulate the system’s behaviour, potentially leading to unauthorized access, data corruption, or even a full system takeover. The fact that this vulnerability can be exploited by a local, privileged user makes it especially dangerous in scenarios where insider threats are a concern.
Conceptual Example Code
The following is a conceptual example of how the vulnerability might be exploited. This is a hypothetical shell command that injects malicious code into the system:
$ echo "malicious_code" > /ibm/integration/bus/install/directory/vulnerable_fileIn this example, “malicious_code” represents the command or payload the attacker wishes to execute on the system.
