Vulnerability Details

The CVE-2025-15101 vulnerability allows remote authenticated administrators to execute arbitrary system commands through the web management interface of affected ASUS router models. Official descriptions highlight the potential for exploitation in environments where these routers are deployed. The vulnerability is classified under CWE-78, which pertains to OS command injection.The CVSS score of 8.6 indicates a high severity level, primarily due to the potential impacts on confidentiality, integrity, and availability. The vulnerability affects all versions of the ASUS firmware prior to version 3.0.0.6_102, which highlights the importance of timely remediation.

Technical Analysis

The root cause of CVE-2025-15101 lies in improper handling of user input in the web management interface. Attackers can exploit this flaw by sending crafted requests that contain malicious parameters, leading to arbitrary command execution on the router.The attack vector is classified as network-based, with a low attack complexity and high privileges required for successful exploitation. This means that an attacker must be authenticated as an administrator, but once authenticated, they can execute commands without user interaction, thereby bypassing typical security controls.

Risk & Impact Analysis

Risk to organizations includes the potential for unauthorized access to sensitive network functions, leading to further compromise of connected systems. The blast radius of this vulnerability is significant given the role of routers in network infrastructure.With a CVSS score of 8.6, organizations must address this vulnerability in their priority patch cycle. The urgency is further emphasized by the possibility of exploitation. Organizations should remain vigilant in monitoring their network environments for any signs of exploitation or unusual activity.

Exploitation Status

Affected Versions

All versions of the ASUS firmware prior to version 3.0.0.6_102 are affected by this vulnerability. Organizations should ensure their devices are updated to this version or later to mitigate the risk.

Mitigation & Remediation

Organizations should prioritize patching their ASUS router firmware to version 3.0.0.6_102 or later. If immediate patching is not feasible, consider implementing network segmentation to limit access to affected devices.Additionally, organizations may enhance security by disabling remote management features if they are not required. Monitoring network traffic for any unusual activity is also recommended to detect potential exploitation attempts.For further information on securing devices, organizations can refer to the comprehensive guidance provided in the application security assessment.

Detection Guidance

Organizations should monitor logs for any unusual command execution patterns originating from the web management interface of ASUS routers. Additionally, tracking failed login attempts can help identify potential unauthorized access attempts.Behavioral anomalies, such as unexpected traffic patterns or system behavior, should be closely analyzed to detect any exploitation attempts.
