Description

Adversaries may abuse Unix shell commands and scripts for execution.

Security Summary

CVE-2024-54802 is a stack-based buffer overflow vulnerability in the UPNP service (/usr/sbin/upnp) on the Netgear WNR854T router version 1.5.2 for North America. The flaw is triggered by processing the M-SEARCH Host header and is associated with CWE-77 (Command Injection). It received 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 network accessibility and potential for severe impacts.

A remote, unauthenticated attacker can exploit this vulnerability by sending a specially crafted M-SEARCH request to the UPNP service over the network. No privileges or user interaction are required, enabling low-complexity exploitation that could result in high confidentiality, integrity, and availability impacts, such as remote code execution on the affected device.

Mitigation details are available in the referenced advisory at https://faultpoint.com/post/2025-03-25-8-cves-on-the-wnr854t-junkyard/#802, published prior to the CVE's official disclosure on 2025-03-31.

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?

Stack-based buffer overflow with command injection in publicly exposed UPnP service enables remote unauthenticated RCE (T1190); resulting command execution on Linux-based router maps to Unix Shell (T1059.004).
