Detailsinfo

A vulnerability classified as very critical was found in Deep Sea Electronics DSE855 1.1.0. This vulnerability affects some unknown functionality of the component Multipart Handler. The manipulation with an unknown input leads to a stack-based overflow vulnerability. The CWE definition for the vulnerability is CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

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.
