Summary
CVE-2024-54802 is a critical-severity Command Injection (CWE-77) vulnerability in Netgear Wnr854T Firmware. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 35.0% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-16 (Memory Protection).
Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly addresses the CVE by requiring timely remediation of the known stack-based buffer overflow flaw in the UPNP service through patching or updates.
Mandates validation of the M-SEARCH Host header input to the UPNP service, preventing the buffer overflow triggered by malformed data.
Provides memory protections such as stack canaries and non-executable memory to mitigate exploitation of the stack-based buffer overflow even if invalid input is processed.
MITRE ATT&CK Enterprise TechniquesAI
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).
NVD Description
In Netgear WNR854T 1.5.2 (North America), the UPNP service (/usr/sbin/upnp) is vulnerable to stack-based buffer overflow in the M-SEARCH Host header.
Deeper analysisAI
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.
