VAR-202007-0871
Vulnerability from variot - Updated: 2023-12-18 12:42This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of D-Link DIR-842 3.13B05 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the processing of HNAP GetCAPTCHAsetting requests. The issue results from the lack of proper handling of sessions. An attacker can leverage this vulnerability to execute arbitrary code in the context of the device. Was ZDI-CAN-10083. Zero Day Initiative To this vulnerability ZDI-CAN-10083 Was numbered.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be put into a state. D-Link DIR-842 is a wireless router made by D-Link in Taiwan.
There are security loopholes in the HNAP GetCAPTCHAsetting request processing process in D-Link DIR-842. The vulnerability stems from the network system or product not properly verifying the user's identity
