Improper authentication vulnerability in NEC Corporation Aterm WG1800HP4, WG1200HS3, WG1900HP2, WG1200HP3, WG1800HP3, WG1200HS2, WG1900HP, WG1200HP2, W1200EX(-MS), WG1200HS, WG1200HP, WF300HP2, W300P, WF800HP, WR8165N, WG2200HP, WF1200HP2, WG1800HP2, WF1200HP, WG600HP, WG300HP, WF300HP, WG1800HP, WG1400HP, WR8175N, WR9300N, WR8750N, WR8160N, WR9500N, WR8600N, WR8370N, WR8170N, WR8700N, WR8300N, WR8150N, WR4100N, WR4500N, WR8100N, WR8500N, CR2500P, WR8400N, WR8200N, WR1200H, WR7870S, WR6670S, WR7850S, WR6650S, WR6600H, WR7800H, WM3400RN, WM3450RN, WM3500R, WM3600R, WM3800R, WR8166N, MR01LN MR02LN, WG1810HP(JE) and WG1810HP(MF) all versions allows a attacker to execute an arbitrary command with the root privilege via the internet.
The vulnerability results from improper implementation of the authentication mechanism in the firmware of NEC Aterm devices. An attacker with network access (via the internet) can bypass required authentication without providing any login credentials. As a result, it is possible to upload and execute arbitrary system commands with the highest privileges (root) on the vulnerable device.
The attacker gains full control of the device with root privileges, enabling reading and modification of configuration, interception of network traffic, and use of the device as an entry point to the internal network.
Apply patches available from the manufacturer according to references (https://jpn.nec.com/security-info/secinfo/nv24-001_en.html). Until updating, it is recommended to restrict access to the device management interface only from trusted local networks and block access to the administrative panel from the internet at the firewall level.
All firmware versions of the following NEC Aterm devices: WG1800HP4, WG1200HS3, WG1900HP2, WG1200HP3, WG1800HP3, WG1200HS2, WG1900HP, WG1200HP2, W1200EX(-MS), WG1200HS, WG1200HP, WF300HP2, W300P, WF800HP, WR8165N, WG2200HP, WF1200HP2, WG1800HP2, WF1200HP, WG600HP, WG300HP, WF300HP, WG1800HP, WG1400HP, WR8175N, WR9300N, WR8750N, WR8160N, WR9500N, WR8600N, WR8370N, WR8170N, WR8700N, WR8300N, WR8150N, WR4100N, WR4500N, WR8100N, WR8500N, CR2500P, WR8400N, WR8200N, WR1200H, WR7870S, WR6670S, WR7850S, WR6650S, WR6600H, WR7800H, WM3400RN, WM3450RN, WM3500R, WM3600R, WM3800R, WR8166N, MR01LN, MR02LN, WG1810HP(JE) and WG1810HP(MF)
