CVE-2023-35723 exposes a critical security vulnerability in D-Link DIR-X3260 routers, enabling attackers to execute arbitrary code remotely without authentication, posing severe risks to OT environments reliant on these routers for network connectivity and management. This flaw, stemming from improper validation of user-supplied input, allows attackers to gain unauthorized access and potentially compromise OT systems and processes.
From the CVE database:
D-Link DIR-X3260 prog.cgi SOAPAction Command Injection Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DIR-X3260 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of the SOAPAction request header provided to the prog.cgi endpoint. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-20983.
