CVE-2017-13772

Status: ModifiedHigh (8.8)—

Multiple stack-based buffer overflows in TP-Link WR940N WiFi routers with hardware version 4 allow remote authenticated users to execute arbitrary code via the (1) ping_addr parameter to PingIframeRpm.htm or (2) dnsserver2 parameter to WanStaticIpV6CfgRpm.htm.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
