ChargePoint Home Flex | 5.5.4.13
How the Exploit Works
The vulnerability lies in the ‘uploadsm’ function of the ChargePoint Home Flex 5.5.4.13. The function fails to validate a user-controlled string during bz2 decompression. As a result, malicious actors can manipulate the string to execute arbitrary commands as the ‘nobody’ user. This could potentially lead to a system compromise or data leakage.
Conceptual Example Code
The following conceptual example demonstrates how this vulnerability might be exploited. In this example, the malicious actor sends a POST request with a manipulated string that leads to command execution.
POST /uploadsm HTTP/1.1
Host: target.example.com
Content-Type: application/bzip2
{ "user_controlled_string": "malicious_command_here" }Mitigation Guidance
To mitigate the CVE-2025-54564 vulnerability, it is advised to apply the vendor patch as soon as it’s available. In the meantime, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation measure, helping filter out malicious payloads and thus, protecting the system from potential compromise or data leakage. It is also essential to maintain a regular update and patch management program to ensure protection against such vulnerabilities in the future.
