TP-Link Tapo Camera Flaw Lets Attackers Gain Admin Access Without Password

Two flaws in TP-Link Tapo C200 cameras allow network-adjacent admin access without a password (CVE-2026-15315) or DoS (CVE-2026-15316); fixed in V5_1.4.6.

OPSWAT Unit 515 researchers discovered CVE-2026-15315, an authentication bypass in the Tapo C200's local HTTPS management interface on port 443, where an alternative verification path accepts a replayed device-generated value, letting unauthenticated network-adjacent attackers establish admin sessions. CVE-2026-15316 causes a denial-of-service crash in the camera's HTTPS service via oversized encrypted Wi-Fi credential data during onboarding. TP-Link confirmed both issues after the April 16, 2026 report and released firmware V5_1.4.6 on August 18, 2026. OPSWAT says additional potentially critical findings remain under coordinated disclosure.

Cisco Identity Services Engine RADIUS Denial of Service Vulnerability

Cisco patched a RADIUS flaw in Identity Services Engine letting unauthenticated remote attackers trigger denial of service on ISE nodes.

A vulnerability in the RADIUS feature of Cisco Identity Services Engine allows an unauthenticated remote attacker to cause a denial of service by sending crafted RADIUS requests directly to an affected device. The flaw stems from improper handling of certain RADIUS requests and can render ISE nodes unavailable. In single-node deployments, endpoints that have not yet authenticated would be unable to access the network until the node recovers. Cisco has released software updates addressing the issue.
