D-Link and Tenda Router Stack Overflow Flaws

Stack-based buffer overflow in Tenda F453 router firmware 1.0.0.3 allows authenticated remote attackers to execute arbitrary code or crash the device via the PPTP user configuration interface. The vulnerability resides in the fromPPTPUserSetting function within the httpd component, triggered by manipulating the 'delno' parameter. Publicly available exploit code exists (GitHub), significantly lowering exploitation barriers. CVSS 8.8 reflects high impact across confidentiality, integrity, and availability, though authentication is required (PR:L). EPSS data not provided, but public POC availability elevates real-world risk for exposed management interfaces.

Stack-based buffer overflow in D-Link DIR-513 1.10 router's email configuration interface allows authenticated remote attackers to achieve arbitrary code execution with high impact to confidentiality, integrity, and availability. The vulnerability affects the formSetEmail function via manipulation of the curTime parameter. Publicly available exploit code exists on GitHub, significantly lowering the exploitation barrier. CRITICAL LIMITATION: This product reached end-of-life and receives no security updates from D-Link, making this a permanent risk for deployed devices. CVSS 8.8 with low attack complexity and CVSS:3.1 Exploit Maturity 'Proof-of-Concept' confirms immediate exploitability.
