Authenticated OS Command Injection in TL-WR841N IPv6 WAN Configuration

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

TP-Link TL-WR841N contains an authenticated OS command injection vulnerability in the IPv6 WAN configuration. A crafted IPv6 Gateway value is improperly incorporated into a system command, allowing an authenticated administrator to execute arbitrary operating system commands.  Successful exploitation may allow unauthorized access to sensitive information, modification of device configuration or services, and disruption of device operation.
