CVE-2025-50428 is a command injection vulnerability identified in the RaspAP project, specifically affecting the raspap-webgui component version 3.3.2 and earlier. The vulnerability resides in the includes/hostapd.php script, where user input passed via the 'interface' parameter is not properly sanitized. This improper input validation allows an attacker to inject arbitrary commands that the system executes with the privileges of the web server process. Since RaspAP is a popular open-source software solution used to configure and manage wireless access points on Raspberry Pi devices, this vulnerability could allow attackers to execute arbitrary commands remotely, potentially leading to full system compromise. The lack of a CVSS score indicates that the vulnerability has been recently published and not yet fully assessed. No known exploits are reported in the wild at this time. The vulnerability's exploitation does not require authentication or user interaction, increasing its risk profile. However, the impact depends on the deployment context and the privileges of the web server user. The vulnerability is critical because command injection can lead to complete system takeover, data exfiltration, or pivoting within a network.

For European organizations, the impact of this vulnerability can be significant, especially for those using Raspberry Pi devices running RaspAP to manage wireless networks. Compromise of these devices could lead to unauthorized access to internal networks, interception of sensitive communications, or use of the compromised device as a foothold for further attacks. Organizations in sectors such as education, research, small and medium enterprises, and IoT deployments that rely on Raspberry Pi-based wireless infrastructure are particularly at risk. Given the widespread use of Raspberry Pi devices in Europe for both professional and hobbyist purposes, exploitation could affect a broad range of environments. Additionally, compromised devices could be leveraged in botnets or for launching attacks against other targets, increasing the overall threat landscape. The lack of authentication requirement for exploitation exacerbates the risk, potentially allowing remote attackers to exploit vulnerable devices exposed to the internet or accessible within internal networks.

To mitigate this vulnerability, European organizations should immediately identify all Raspberry Pi devices running RaspAP, particularly versions 3.3.2 and earlier. Since no official patch links are currently available, organizations should monitor the RaspAP project for updates or patches addressing this vulnerability and apply them promptly once released. In the interim, restricting network access to the web interface of RaspAP devices is critical; this can be achieved by implementing firewall rules that limit access to trusted IP addresses only. Disabling or restricting the use of the vulnerable 'interface' parameter in hostapd.php, if feasible, can reduce risk. Organizations should also consider isolating Raspberry Pi devices on segmented networks to limit lateral movement in case of compromise. Regularly auditing device configurations and monitoring network traffic for unusual activity can help detect exploitation attempts. Finally, educating users and administrators about the risks of exposing management interfaces to untrusted networks is essential.
