Overview
The Common Vulnerabilities and Exposures (CVE) system has disclosed a significant vulnerability in RaspAP raspap-webgui 3.3.2 and earlier versions. This vulnerability, identified as CVE-2025-50428, is a command injection flaw that exists due to the improper sanitization of user input. This vulnerability directly impacts the includes/hostapd.php script, making it a critical issue that needs prompt attention. This issue is noteworthy as it can potentially lead to system compromises and data leakage if exploited successfully, affecting anyone who operates on these versions of RaspAP raspap-webgui.

How the Exploit Works
The vulnerability stems from the improper sanitization of user input which is passed via the interface parameter in the includes/hostapd.php script. As a result, an attacker can inject malicious commands into this parameter. When the system processes this input, it inadvertently executes these commands, leading to potential unauthorized access, system compromise, or data leakage.
Conceptual Example Code
While this is purely conceptual and not an actual exploit, the following snippet provides an idea of how an attacker might exploit this vulnerability. This could be a sample HTTP request, where the attacker injects a malicious command into the interface parameter.
POST /includes/hostapd.php HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
interface=;[malicious command]In this example, the malicious command would be executed by the system, potentially leading to unauthorized actions.
Mitigation Measures
To mitigate the risk posed by the CVE-2025-50428 vulnerability, it is strongly recommended to apply the vendor patch as soon as it’s available. In the interim, usage of Web Application Firewalls (WAF) or Intrusion Detection Systems (IDS) can provide a temporary mitigation. Additionally, it’s good practice to ensure that all user inputs are sanitized properly to prevent such command injection vulnerabilities.
