Buffer overflow vulnerability in TP-Link TL-WR940N V4 and TL-WR841N V11 routers, exploitable remotely through the /userRpm/WanSlaacCfgRpm.htm endpoint. An attacker with high privileges can trigger memory corruption leading to availability impact (denial of service) or potential system compromise. This vulnerability affects end-of-life products no longer receiving vendor support, significantly limiting remediation options.
TP-Link TL-WR940N V3 and V4 with firmware 3.16.9 and earlier contain a buffer overflow via the dnsserver1 and dnsserver2 parameters at /userRpm/Wan6to4TunnelCfgRpm.htm. Rated high severity (CVSS 8.0), this vulnerability is low attack complexity. No vendor patch available.
