Tp-Link: Security Vulnerabilities
The HTTP parser of Tapo C210 v3, C220 v1 and C520WS v2 cameras improperly handles requests containing an excessively long URL path. An invalid‑URL error path continues into cleanup code that assumes allocated buffers exist, leading to a crash and service restart. An unauthenticated attacker can force repeated service crashes or device reboots, causing denial of service.

By sending crafted files to the firmware update endpoint of Tapo C220 v1 and C520WS v2, the device terminates core system services before verifying authentication or firmware integrity. An unauthenticated attacker can trigger a persistent denial of service, requiring a manual reboot or application initiated restart to restore normal device operation.

The Tapo C100 v5, C220 v1 and C520WS v2 cameras’ HTTP service does not safely handle POST requests containing an excessively large Content-Length header. The resulting failed memory allocation triggers a NULL pointer dereference, causing the main service process to crash. An unauthenticated attacker can repeatedly crash the service, causing temporary denial of service. The device restarts automatically, and repeated requests can keep it unavailable.

An authentication weakness was identified in Omada Controllers, Gateways and Access Points, controller-device adoption due to improper handling of random values. Exploitation requires advanced network positioning and allows an attacker to intercept adoption traffic and forge valid authentication through offline precomputation, potentially exposing sensitive information and compromising confidentiality.

A Cross-Site Scripting (XSS) vulnerability was identified in a parameter in Omada Controllers due to improper input sanitization. Exploitation requires advanced conditions, such as network positioning or emulating a trusted entity, and user interaction by an authenticated administrator. If successful, an attacker could execute arbitrary JavaScript in the administrator’s browser, potentially exposing sensitive information and compromising confidentiality.

Logic vulnerability in TP-Link Archer C20 v5, 6.0, Archer AX53 v1.0 and TL-WR841N v13 (TDDP module) allows unauthenticated adjacent attackers to execute administrative commands including factory reset and device reboot without credentials. Attackers on the adjacent network can remotely trigger factory resets and reboots without credentials, causing configuration loss and interruption of device availability.
