Aterm Wg2600Hm4
Monthly
Multiple NEC Aterm wireless router models are vulnerable to OS command injection that enables network-based attackers with high privileges and user interaction to execute arbitrary operating system commands. The vulnerability carries a CVSS 4.0 score of 7.1 and affects at least eight router models in the Aterm series including WG2600HS, WF1200CR, WG1200CR, WG2600HP4, WG2600HM4, WG2600HS2, WX3000HP, and WX3000HP2. No public exploit identified at time of analysis, though exploitation requires both elevated privileges and user interaction which reduces immediate risk.
NEC Aterm wireless router series (including WG1200HP2, WG1900HP, WG1800HP3, WG1200HP4, and nine other models) contain hidden telnet functionality that can be remotely enabled by unauthenticated network attackers via unspecified means, classified as CWE-912 (Hidden Functionality). The vulnerability carries a CVSS 6.3 score reflecting network-accessible attack vector with high complexity requirements and limited confidentiality/integrity impact. No public exploit code or active exploitation via CISA KEV has been confirmed at analysis time, though the remote enablement of administrative telnet access represents a significant privilege escalation pathway for subsequent unauthorized system access.
NEC Aterm wireless router series (W1200Ex-MS, WG1200HP2, WG1900HP, WG1800HP3, WG1800HP4, WG1200HP3, WG1200HP4, WG1200HS2, WG1200HS3, WX1500HP, WX3000HP, WX3600HP, WG2600HS, WG2600HS2, WG2600HP4, WG2600HM4, WF1200CR, WG1200CR, and others) suffer from missing authorization controls that enable remote attackers to enumerate device configuration details and modify settings without proper access controls. The vulnerability stems from CWE-862 (Missing Authorization) in the device management interface, allowing unauthenticated or inadequately authenticated network-accessible requests to interact with sensitive administrative functions. No CVSS score, EPSS probability estimate, or public exploit code has been disclosed, and CISA KEV status is unknown.
