Incorrect access control in the realtime.cgi endpoint of Deep Sea Electronics devices DSE855 v1.1.0 to v1.1.26 allows attackers to gain access to the admin panel and complete control of the device.

Deep Sea Electronics DSE855 Restart Missing Authentication Denial-of-Service Vulnerability

Deep Sea Electronics DSE855 Restart Missing Authentication Denial-of-Service Vulnerability. This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of Deep Sea Electronics DSE855 devices. Authentication is not required to exploit this vulnerability. The specific flaw exists within the web-based UI. The issue results from the lack of authentication prior to allowing access to functionality. An attacker can leverage this vulnerability to create a denial-of-service condition on the system. Was ZDI-CAN-23174.

Deep Sea Electronics DSE855 Multipart Boundary Stack-Based Buffer Overflow Remote Code Execution Vulnerability

Deep Sea Electronics DSE855 Multipart Boundary Stack-Based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Deep Sea Electronics DSE855 devices. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of multipart boundaries. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the device. Was ZDI-CAN-23170.
