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.
