PatchTheCVECVE-2024-54807: In Netgear WNR854T 1.5.2 (North America), the UPNP service is vulnerable to command injection in the function
CVE-2024-54807 is a critical-severity flaw (CVSS 9.8) affecting wnr854t firmware. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
In Netgear WNR854T 1.5.2 (North America), the UPNP service is vulnerable to command injection in the function addmap_exec which parses the NewInternalClient parameter of the AddPortMapping SOAPAction into a system call without sanitation. An attacker can send a specially crafted SOAPAction request for AddPortMapping via the router's WANIPConn1 service to achieve arbitrary command execution.
Why this priority
- Critical severity
- Public exploit reference
- CISA SSVC: automatable with total technical impact
- Remotely exploitable, no login, no user action
A fixed release or distro patch exists.
