Tapo C200 Firmware
Monthly
Denial-of-service in TP-Link Tapo C200 v5 IP cameras allows adjacent-network unauthenticated attackers to crash the device's configuration service by submitting oversized encrypted ciphertext payloads that trigger unhandled exceptions. Affected firmware versions prior to V5_1.4.6 Build 260709 Rel.27675n are confirmed vulnerable per ENISA EUVD-2026-62194; successful exploitation temporarily disables HTTPS management and monitoring until the service self-recovers, with no confidentiality or integrity impact. No public exploit code has been identified and the vulnerability is not listed in the CISA KEV catalog at time of analysis.
Authentication bypass in TP-Link Tapo C200 v5 IP cameras running firmware below V5_1.4.6 Build 260709 Rel.27675n allows unauthenticated adjacent-network attackers to manipulate challenge parameters during the login handshake, circumventing the authentication verification module and obtaining valid administrative session tokens. With those tokens, an attacker can execute privileged management operations - including reconfiguring the camera, accessing live or recorded footage, and deliberately disrupting device services to cause a denial-of-service condition. No public exploit identified at time of analysis, and the adjacent-network requirement (AV:A) constrains exposure to attackers already present on the same LAN or Wi-Fi segment.
Stack-based buffer overflow in the ONVIF SOAP XML parser of TP-Link Tapo C200 v3 (firmware ≤1.4.1) and C520WS v2.6 cameras enables unauthenticated remote code execution from adjacent networks. Attackers can send crafted SOAP requests with oversized namespace prefixes to trigger memory corruption and achieve full device compromise with elevated privileges. EPSS probability and KEV status indicate no public exploit identified at time of analysis, though the vulnerability affects widely deployed consumer IoT cameras with network exposure.
Missing authentication on the HTTPS connectAP interface in TP-Link Tapo C200 V3 firmware (versions 1.3.3 through 1.4.1) allows adjacent network attackers to remotely reconfigure device Wi-Fi settings, causing permanent denial-of-service until manual intervention. The vulnerability exploits CWE-306 (Missing Authentication for Critical Function) with CVSS 8.7 severity, requiring only adjacent network access with low attack complexity and no user interaction. No public exploit code or active exploitation (CISA KEV) has been identified at time of analysis, though the technical barrier is minimal for LAN-positioned adversaries.
The AES Key-IV pair used by the TP-Link TAPO C200 camera V3 (EU) on firmware version 1.1.22 Build 220725 is reused across all cameras. Rated medium severity (CVSS 4.6), this vulnerability is no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
TP-Link cloud cameras through 2020-02-09 allow remote attackers to bypass authentication and obtain sensitive information via vectors involving a Wi-Fi session with GPS enabled, aka CNVD-2020-04855. Rated medium severity (CVSS 5.3), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
