Details
A vulnerability has been found in TP-Link Tapo D230S1 up to 1.2.1 and classified as critical. Affected by this vulnerability is some unknown processing. The manipulation with an unknown input leads to a missing protection mechanism for alternate hardware interface vulnerability. The CWE definition for the vulnerability is CWE-1299. The lack of protections on alternate paths to access
control-protected assets (such as unprotected shadow registers
and other external facing unguarded interfaces) allows an
attacker to bypass existing protections to the asset that are
only performed against the primary path. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:
The attacker may obtain root access by connecting to the UART port and this vulnerability requires the attacker to have the physical access to the device. This issue affects Tapo D230S1 V1.20: before 1.2.2 Build 20250907.
