An Improper Access Control vulnerability allows an attacker to access the control panel of the B420 without requiring any sort of authorization or authentication due to the IP based authorization. If an authorized user has accessed a publicly available B420 product using valid credentials, an insider attacker can gain access to the same panel without requiring any sort of authorization. The B420 module was already obsolete at the time this vulnerability was found (The End of Life announcement was made in 2013).

Logic Vulnerability on TP-Link Archer C20, Archer AX53 and TL-WR841N v13

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. This issue affects Archer C20 v6.0 < V6_251031, Archer C20 v5 <EU_V5_260317 or < US_V5_260419 Archer AX53 v1.0 < V1_251215 TL-WR841N v13 < 0.9.1 Build 20231120 Rel.62366

The custom GINA/CP module in ANIXIS Password Reset Client before version 3.22 allows remote attackers to execute code and escalate privileges via spoofing. When the client is configured to use HTTP, it does not authenticate the intended server before opening a browser window. An unauthenticated attacker capable of conducting a spoofing attack can redirect the browser to gain execution in the context of the WinLogon.exe process. If Network Level Authentication is not enforced, the vulnerability can be exploited via RDP.
