Detailsinfo

A vulnerability, which was classified as critical, has been found in Deep Sea Electronics DSE855 1.1.0. This issue affects an unknown part of the component Multipart Handler. The manipulation with an unknown input leads to a stack-based overflow vulnerability. Using CWE to declare the problem leads to 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). Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Deep Sea Electronics DSE855 Multipart Value Handling 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 form variables. 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-23172.

The advisory is shared at zerodayinitiative.com. The identification of this vulnerability is CVE-2024-5950 since 06/13/2024. The exploitation is known to be easy.
