CVE-2023-34277 is a high-severity vulnerability rated 8/10 on the CVSS scale. D-Link DIR-2150 SetSysEmailSettings AccountName Command Injection Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DIR-2150 routers. EPSS estimates a 1.76% chance of exploitation in the next 30 days.

Description

D-Link DIR-2150 SetSysEmailSettings AccountName Command Injection Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DIR-2150 routers. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the SOAP API interface, which listens on TCP port 80 by default. 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-20555.
