    Vulnerability from variot - Updated: 2025-11-19 23:10

    D-Link DIR-2640 DestNetwork Command Injection Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DIR-2640 routers. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed.

    The specific flaw exists within the handling of the DestNetwork parameter provided to the HNAP1 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-19548. D-Link Systems, Inc. of DIR-2640 The firmware has OS A command injection vulnerability exists.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. The D-Link DIR-2640 is a high-power Wi-Fi router from D-Link (Taiwan), supporting the AC2600 WiFi standard and featuring dual-band (2.4GHz and 5GHz) network transmission

    Vulnerability from variot - Updated: 2025-10-15 23:31

    D-Link DIR-2640 LocalIPAddress Command Injection Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DIR-2640 routers. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed.

    The specific flaw exists within the handling of the LocalIPAddress parameter provided to the HNAP1 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-19544. D-Link Systems, Inc. of DIR-2640 The firmware has OS A command injection vulnerability exists.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. The D-Link DIR-2640 is a high-power Wi-Fi router manufactured by D-Link in Taiwan

    Vulnerability from variot - Updated: 2025-08-09 23:09

    D-Link DIR-2640 HTTP Referer Stack-Based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DIR-2640-US routers. Authentication is not required to exploit this vulnerability.

    The specific flaw exists within prog.cgi, which handles HNAP requests made to the lighttpd webserver listening on TCP ports 80 and 443. 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 root. Was ZDI-CAN-21853. D-Link Systems, Inc. (DoS) It may be in a state. D-Link DIR-2640 is a high-power Wi-Fi router from D-Link, a Chinese company.

    D-Link DIR-2640 has a buffer overflow vulnerability. The vulnerability is caused by the program failing to properly verify the length of the input data

    Vulnerability from variot - Updated: 2025-08-09 22:53

    D-Link DIR-2640 HNAP LoginPassword Authentication Bypass Vulnerability. This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of D-Link DIR-2640 routers. Authentication is not required to exploit this vulnerability.

    The specific flaw exists within the web management interface, which listens on TCP port 80 by default. A specially crafted login request can cause authentication to succeed without providing proper credentials. An attacker can leverage this vulnerability to bypass authentication on the system. Was ZDI-CAN-19549. D-Link Systems, Inc. of DIR-2640 The firmware contains a vulnerability related to an improper implementation of the authentication algorithm.Information may be tampered with. D-Link DIR-2640 is a high-power Wi-Fi router from China's D-Link

    Vulnerability from variot - Updated: 2025-08-09 22:53

    D-Link DIR-2640 EmailFrom Command Injection Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DIR-2640 routers. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed.

    The specific flaw exists within the handling of the EmailFrom parameter provided to the HNAP1 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-19550. D-Link Systems, Inc. of DIR-2640 The firmware has OS A command injection vulnerability exists.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. D-Link DIR-2640 is a high-power Wi-Fi router from China's D-Link
