Overview

The cybersecurity landscape continues to evolve with increasingly complex vulnerabilities being identified and exploited. One such vulnerability, identified as CVE-2025-3753, has been found in the Robot Operating System (ROS) ‘rosbag’ tool. This vulnerability specifically affects ROS distributions Noetic Ninjemys and earlier versions. It is a serious issue because it allows attackers to execute arbitrary Python code, potentially compromising the entire system or resulting in data leakage.
This vulnerability highlights the importance of stringent input sanitization, as its root cause is the use of the eval() function to process unsanitized, user-supplied input. Given the widespread use of ROS in robotics, this vulnerability could have far-reaching implications if left unaddressed, making it a matter of utmost concern for cybersecurity.

Vulnerability Summary

CVE ID: CVE-2025-3753
Severity: High (7.8 CVSS Score)
Attack Vector: Network
Privileges Required: Low
User Interaction: Required
Impact: System compromise or data leakage

Affected Products

Product | Affected Versions

ROS ‘rosbag’ Tool | Noetic Ninjemys and earlier versions

How the Exploit Works

The exploit takes advantage of the ‘rosbag filter’ command in the ROS ‘rosbag’ tool. The command uses the eval() function to process user-supplied input without properly sanitizing it. This allows an attacker to input malicious Python code that gets executed by the eval() function. The attacker can craft this code to compromise the system or cause data leakage.

Conceptual Example Code

Consider the following conceptual example: an attacker could exploit this vulnerability by passing a ‘rosbag filter’ command with a malicious Python payload. Below is a pseudocode representation of this:

rosbag filter 'eval(__import__("os").system("malicious_command"))' input.bag output.bag

In this conceptual example, `malicious_command` could be any command that the attacker wants to execute on the target system. This code exploits the eval() function’s ability to execute Python code from a string, which in this case, is a command to execute an arbitrary system command.
