CVE-2024-54806
Published: 31 March 2025
Summary
CVE-2024-54806 is a critical-severity Code Injection (CWE-94) 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 23.4% 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-2 (Flaw Remediation).
Deeper analysis
CVE-2024-54806 is an arbitrary command execution vulnerability in the cmd.cgi component of the Netgear WNR854T router version 1.5.2 (North America). It allows attackers to execute system commands via the web interface, stemming from improper input handling classified under CWE-94 (Code Injection). The flaw carries 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 high impact potential.
A remote, unauthenticated attacker can exploit this vulnerability over the network with low complexity and no user interaction required. By crafting requests to the cmd.cgi endpoint, the attacker achieves arbitrary command execution on the router's underlying system, enabling full compromise with high confidentiality, integrity, and availability impacts, such as data theft, persistent access, or device disruption.
