Lifecycle Timeline
1DescriptionNVD
A stack-based buffer overflow in the upnpd binary running on NETGEAR WNDR3400v3 routers with firmware version 1.0.1.18_1.0.63 allows an attacker to remotely execute arbitrary code via a crafted UPnP SSDP packet.
AnalysisAI
A stack-based buffer overflow in the upnpd binary running on NETGEAR WNDR3400v3 routers with firmware version 1.0.1.18_1.0.63 allows an attacker to remotely execute arbitrary code via a crafted UPnP. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
Technical ContextAI
This vulnerability is classified as Out-of-bounds Write (CWE-787), which allows attackers to write data beyond allocated buffer boundaries leading to code execution or crashes. A stack-based buffer overflow in the upnpd binary running on NETGEAR WNDR3400v3 routers with firmware version 1.0.1.18_1.0.63 allows an attacker to remotely execute arbitrary code via a crafted UPnP SSDP packet. Affected products include: Netgear Wndr3400V3 Firmware. Version information: version 1.0.1.18.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Validate write boundaries, use memory-safe languages, enable compiler protections (ASLR, stack canaries).
