Technical ContextAI · show details
This vulnerability is classified as Code Injection (CWE-94), which allows attackers to inject and execute arbitrary code within the application. Netgear WNR854T 1.5.2 (North America) is vulnerable to Command Injection. An attacker can send a specially crafted request to post.cgi, updating the nvram parameter wan_hostname and forcing a reboot. This will result in command injection. Affected products include: Netgear Wnr854T Firmware.

Netgear WNR854T 1.5.2 (North America) is vulnerable to Command Injection. An attacker can send a specially crafted request to post.cgi, updating the nvram parameter wan_hostname and forcing a reboot. This will result in command injection.
Executive ViewAI
CVE-2024-54804 presents critical security risk, a code injection vulnerability rated CVSS 9.8. Successful exploitation could allow attackers to execute arbitrary code or commands on affected systems, potentially leading to full system compromise. With an EPSS score of 10%, exploitation is likely in exposed deployments. Organizations should apply vendor updates immediately when available and implement compensating controls in the interim.
Apply vendor patch. If immediate patching is not feasible: (1) Deploy WAF rules to block injection patterns; (2) Restrict network access to affected components; (3) Enable enhanced logging for suspicious activity.

The engine reads each signal below and applies a fixed list of rules from top to bottom. The first rule that matches sets the recommended action – like a statement, every line is shown.
What every action level means
SSVC AssessmentENISA
Priority Score
Attack Technique
OS command injection occurs when an application passes unsanitized user input directly into system shell commands.
Code injection occurs when an application accepts user input and passes it directly into a language interpreter or evaluator without proper sanitization.
Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
