Authenticated OS command execution in NEC Platforms Aterm MR51FN (before Ver. 3.4.0) and CM51FD (before Ver. 1.2.0) routers lets an attacker who already holds administrator credentials to the web console inject arbitrary operating-system commands over an adjacent network. Impact is total (confidentiality, integrity and availability all High per CVSS 4.0), effectively giving full control of the affected device, but there is no public exploit identified at time of analysis and EPSS exploitation probability is low (0.34%, 57th percentile). Exploitation is gated behind administrator access and adjacent (not internet-wide) reach, so this is a privilege-escalation-to-device-takeover primitive rather than a remote unauthenticated compromise.
OS command injection in NEC Platforms Aterm wireless router series (models WX1500HP and WX3600HP) permits authenticated network attackers with high privileges to execute arbitrary operating system commands on affected devices. The vulnerability requires user interaction and high attack complexity (CVSS 4.0 score 7.1), with no public exploit identified at time of analysis. NEC Platforms has published a security advisory detailing the issue.
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.
Cross-site scripting in NEC Aterm router web management interfaces allows an adjacent-network attacker to inject and execute arbitrary JavaScript in the browser of any user who visits the management UI. Nine router models across the Aterm WX, GX, SH, and 19000 series are confirmed affected, with patched firmware versions identified for each. No public exploit identified at time of analysis and EPSS sits at 0.03% (9th percentile), indicating very low observed exploitation pressure; CISA SSVC also assesses exploitation as none.
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 WX3600HP routers contain a path traversal vulnerability enabling remote attackers to write arbitrary files to the device via network access, potentially compromising system integrity and enabling persistent attacks. The vulnerability (CVE-2026-4619) affects the Aterm WX3600HP model and exploits insufficient input validation in file handling mechanisms. No CVSS score or publicly available exploit has been identified at the time of analysis, though the CWE-22 classification confirms the path traversal root cause.
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.
