    Vulnerability from variot - Updated: 2024-11-23 22:20

    This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DVA-2800 and DSL-2888A routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the dhttpd service, which listens on TCP port 8008 by default. When parsing the path parameter, the process does not properly validate 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 the web server. Was ZDI-CAN-10911. D-Link DVA-2800 and DSL-2888A A command injection vulnerability exists in the router. Zero Day Initiative To this vulnerability ZDI-CAN-10911 Was numbered.Information is obtained, information is tampered with, and service is disrupted (DoS) It may be put into a state. D-link DSL-2888A is a unified service router of China D-link Corporation. The vulnerability stems from the fact that the network system or product does not properly filter special elements in the process of constructing executable commands from external input data

    Vulnerability from variot - Updated: 2024-11-23 22:20

    This vulnerability allows network-adjacent attackers to disclose sensitive information on affected installations of D-Link DVA-2800 and DSL-2888A routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the dhttpd service, which listens on TCP port 8008 by default. The issue results from incorrect string matching logic when accessing protected pages. An attacker can leverage this vulnerability to disclose stored credentials, leading to further compromise. Was ZDI-CAN-10912. Zero Day Initiative To this vulnerability ZDI-CAN-10912 Was numbered.Information may be obtained
