CVE-2025-22906 is a critical command injection vulnerability discovered in Edimax RE11S firmware version 1.11. This vulnerability allows attackers to exploit the device via the L2TPUserName parameter at /goform/setWAN, leading to unauthorized command execution.
With a CVSS score of 9.8, this vulnerability is classified as critical, indicating a severe threat to organizations using affected devices. The risk to organizations includes potential unauthorized access and data breaches.
Currently, there are no known public exploits or proof-of-concept (PoC) available for this vulnerability. However, organizations should remain vigilant as the potential for exploitation exists.
Organizations should prioritize patching immediately to mitigate the risk associated with this vulnerability.
Vulnerability Details
The vulnerability is identified as CWE-94 (Improper Control of Generation of Code ('Code Injection')). It is exploitable over the network with low complexity and does not require any privileges or user interaction. The impact on confidentiality, integrity, and availability is high, making it essential for organizations to address this issue immediately.
Technical Analysis
The root cause of this vulnerability is the improper handling of user input in the L2TPUserName parameter during the WAN configuration process. Attackers may leverage this flaw to inject malicious commands, resulting in potential system compromise.
The attack vector is network-based, allowing remote attackers to exploit the vulnerability without direct access to the device. The attack complexity is low, making it easier for attackers to execute their exploits.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2025-22906 is significant due to its high CVSS score and potential for serious impact. Organizations using the affected Edimax RE11S firmware are at risk of unauthorized access and command execution, which could lead to data exfiltration, system disruption, or further exploitation of connected systems.
Given the critical nature of this vulnerability, organizations should address it in their priority patch cycle. Failure to do so could expose them to significant risks.
