CVE-2025-55112: Critical Blowfish Cryptography Vulnerability in Control-M/Agent

Overview

This report examines the recently discovered CVE-2025-55112 vulnerability. This critical issue impacts out-of-support Control-M/Agent versions 9.0.18 to 9.0.20, and potentially earlier unsupported versions, when configured to use the non-default Blowfish cryptography algorithm. This vulnerability poses a severe threat to the confidentiality and integrity of data as it allows unauthorized decryption of network traffic, leading to potential system compromise or data leakage.

How the Exploit Works

The exploit hinges on the hardcoded key used in Blowfish cryptography in Control-M/Agent. An attacker with access to network traffic can use this key to decrypt traffic between the Control-M/Agent and Server. This allows for unauthorized access to sensitive information, leading to potential system compromise or data leakage.

Conceptual Example Code

Given the nature of this vulnerability, a conceptual example would involve an attacker intercepting network traffic and decrypting it with the hardcoded key. The following pseudocode illustrates this:

def exploit(network_traffic, hardcoded_key):
decrypted_traffic = blowfish_decrypt(network_traffic, hardcoded_key)
return decrypted_traffic

In the above pseudocode, `network_traffic` represents the intercepted network traffic between Control-M/Agent and Server, and `hardcoded_key` stands for the hardcoded key used in Blowfish cryptography. The function `blowfish_decrypt` is a hypothetical function representing the decryption of network traffic using the Blowfish algorithm with the hardcoded key.
By executing this code, an attacker could potentially access sensitive information, compromising the security of the affected system and potentially leading to data leakage.
