Credential interception in TP-Link Omada's device adoption process exposes site management authentication to offline cracking due to use of a weak, unsalted hash algorithm (CWE-759). An adjacent-network attacker who captures adoption-phase traffic can recover plaintext credentials and authenticate to the Omada controller or managed devices including gateways, switches, access points, and OLTs. No public exploit identified at time of analysis, but a vendor patch is available; the CVSS 4.0 score of 6.9 reflects meaningful real-world constraints including network adjacency, high attack complexity, and a required adoption event.
Improper certificate hostname validation in TP-Link Omada networking devices (gateways, switches, and access points) allows a network-positioned attacker to intercept or modify encrypted management traffic between those devices and their cloud controllers. The flaw - classified as CWE-295 - means the devices do not adequately confirm that a presented TLS certificate belongs to the expected cloud controller hostname, enabling a machine-in-the-middle to substitute a fraudulent certificate and break the trust boundary. No active exploitation is confirmed (not in CISA KEV) and no public proof-of-concept has been identified at time of analysis; vendor has released patched firmware.
Hardcoded credentials in TP-Link router firmware allow attackers with physical access to gain unauthorized access to privileged functions, potentially leading to full device compromise. Affected models include TL-WR845N v4, TL-WR850N v3, Archer C20 v6, and Archer MR200 v5. No evidence of active exploitation or public exploit code exists at this time, and the physical access requirement limits remote exploitation risk.
Unauthenticated information disclosure in TP-Link Kasa EC70 v4 and EC71 v4 exposes sensitive geolocation data to any attacker on the same local network segment.

No public exploit code or CISA KEV listing has been identified at time of analysis; the vendor (TP-Link) has released a firmware patch.
Stored XSS in the TP-Link TL-SG108PE v5 web management interface allows an authenticated administrator on an adjacent network to inject persistent malicious script via the SYSNAM configuration parameter during a config file import operation. The injected payload is stored on the device and executes in any administrator's browser upon viewing the affected management page, enabling session cookie theft, unauthorized configuration changes, or exposure of sensitive management-plane data. No public exploit code has been identified at time of analysis, and CISA SSVC assessment rates exploitation as none and not automatable, consistent with the high privilege and adjacency prerequisites.
Improper error handling in the TP-Link Archer AX72 (SG) v1.0 web management interface allows an authenticated administrative user to extract diagnostic command syntax by submitting invalid input to the network diagnostic feature. The disclosure is narrow - limited to command-line usage information for the underlying diagnostic utility - and does not expose credentials, configuration data, or sensitive system state. A vendor-released patch is available, no public exploit code has been identified, and the vulnerability carries no CISA KEV designation.
Weak cryptography in the TDDPv2 debug protocol on TP-Link TL-WR841N v13 routers exposes devices left in default configuration to network-adjacent attackers. DES-CBC encryption - an algorithm deprecated for over a decade - is keyed from the device's default web management credentials, meaning the cryptographic secret is fully predictable without any credential theft. An attacker sharing the same network segment can exploit this to access the debug protocol unauthenticated, exfiltrate debug output, alter device configuration, and force reboots, resulting in integrity loss and denial of service. No public exploit code has been identified at time of analysis, and CISA SSVC rates exploitation as none with partial technical impact.
