Description

Adversaries may abuse Unix shell commands and scripts for execution.

Security Summary

CVE-2024-54805 is a command injection vulnerability (CWE-94) affecting the Netgear WNR854T router running firmware version 1.5.2 for North America. The issue exists in the web interface endpoints post.cgi and send_log.cgi, where the nvram parameter "get_email" is mishandled. It has a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating critical severity due to its potential for complete system compromise.

An unauthenticated remote attacker can exploit this vulnerability by sending a specially crafted HTTP request to post.cgi to overwrite the nvram "get_email" parameter with arbitrary commands. The attacker then triggers execution by accessing the send_log.cgi endpoint, which incorporates the tainted parameter into a system call, achieving arbitrary command injection on the underlying operating system.

Details on the vulnerability, including this CVE as one of eight disclosed for the WNR854T, are available in the advisory at https://faultpoint.com/post/2025-03-25-8-cves-on-the-wnr854t-junkyard/#805. No patch or specific mitigation guidance is detailed in available information.

MITRE ATT&CK Enterprise Techniques

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1059.004 Unix Shell Execution
Adversaries may abuse Unix shell commands and scripts for execution.
Why these techniques?

Unauthenticated remote command injection in public web interface endpoints enables T1190 (Exploit Public-Facing Application) for initial access and T1059.004 (Unix Shell) for arbitrary OS command execution via system calls.
