What is CVE-2026-23755?

The D-Link D-View 8 software versions up to 2.0.1.107 is susceptible to an uncontrolled search path vulnerability that affects its installer. When executed with elevated privileges, the installer attempts to load a crucial DLL from its execution directory, which can be manipulated by an attacker. By placing a malicious version.dll in the same directory, attackers can exploit this vulnerability by running the installer, which allows their unauthorized code to execute with administrative privileges. This situation potentially jeopardizes entire systems, necessitating urgent attention and remediation.
