Dlink

An issue was discovered on D-Link 6600-AP and DWL-3600AP Ax 4.2.0.14 21/03/2019 devices. There is an ability to escape to a shell in the restricted command line interface, as demonstrated by the `/bin/sh -c wget` sequence.Show less

An issue was discovered on D-Link 6600-AP, DWL-3600AP, and DWL-8610AP Ax 4.2.0.14 21/03/2019 devices. There is post-authenticated Certificate and RSA Private Key extraction through an insecure sslcert-get.cgi HTTP command.Show less

D-Link DSL-2750U 1.11 is affected by: Authentication Bypass. The impact is: denial of service and information leakage. The component is: login. NOTE: Third parties dispute this issues as not being a vulnerability because although the wizard is accessible without authentication, it can't actually configure anything. Thus, there is no denial of service or information leakageShow less

D-Link DIR-655 C devices before 3.02B05 BETA03 allow XSS, as demonstrated by the /www/ping_response.cgi ping_ipaddr parameter, the /www/ping6_response.cgi ping6_ipaddr parameter, and the /www/apply_sec.cgi html_response_return_page parameter.Show less

A SQL Injection was discovered in D-Link Central WiFi Manager CWM(100) before v1.03R0100_BETA6 in PayAction.class.php with the index.php/Pay/passcodeAuth parameter passcode. The vulnerability does not need any authentication.Show less

A cross-site scripting (XSS) vulnerability in resource view in PayAction.class.php in D-Link Central WiFi Manager CWM(100) before v1.03R0100_BETA6 allows remote attackers to inject arbitrary web script or HTML via the index.php/Pay/passcodeAuth passcode parameter.Show less

An issue was discovered in the D-Link Central WiFi Manager CWM(100) before v1.03R0100_BETA6. Input does not get validated and arbitrary SQL statements can be executed in the database via the /web/Public/Conn.php parameter dbSQL.Show less

/web/Lib/Action/IndexAction.class.php in D-Link Central WiFi Manager CWM(100) before v1.03R0100_BETA6 allows remote attackers to execute arbitrary PHP code via a cookie because a cookie's username field allows eval injection, and an empty password bypasses authentication.Show less

An issue was discovered on D-Link DCS-1100 and DCS-1130 devices. The device requires that a user logging into the device provide a username and password. However, the device allows D-Link apps on the mobile devices and desktop to communicate with the device without any authentication. As a part of that communication, the device uses custom version of base64 encoding to pass data back and forth between the apps and the device. However, the same form of communication can be initiated by any process including an attacker process on the mobile phone or the desktop and this allows a third party to retrieve the device's password without any authentication by sending just 1 UDP packet with custom base64 encoding. The severity of this attack is enlarged by the fact that there more than 100,000 D-Link devices out there.Show less

An issue was discovered on D-Link DCS-1100 and DCS-1130 devices. The device runs a custom daemon on UDP port 5978 which is called "dldps2121" and listens for broadcast packets sent on 255.255.255.255. This daemon handles custom D-Link UDP based protocol that allows D-Link mobile applications and desktop applications to discover D-Link devices on the local network. The binary processes the received UDP packets sent from any device in "main" function. One path in the function traverses towards a block of code that processing of packets which does an unbounded copy operation which allows to overflow the buffer. The custom protocol created by Dlink follows the following pattern: Packetlen, Type of packet; M=MAC address of device or broadcast; D=Device Type;C=base64 encoded command string;test=1111 We can see at address function starting at address 0x0000DBF8 handles the entire UDP packet and performs an insecure copy using strcpy function at address 0x0000DC88. This results in overflowing the stack pointer after 1060 characters and thus allows to control the PC register and results in code execution. The same form of communication can be initiated by any process including an attacker process on the mobile phone or the desktop and this allows a third-party application on the device to execute commands on the device without any authentication by sending just 1 UDP packet with custom base64 encoding.Show less
