CVE-2021-34830 1 Dlink 2 Dap-1330, Dap-1330 Firmware 2021-07-20 8.3 HIGH 8.8 HIGH
This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DAP-1330 1.13B01 BETA routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of the Cookie HTTP header. 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 the device. Was ZDI-CAN-12028.
CVE-2020-29324 1 Dlink 2 Dir-895l Mfc, Dir-895l Mfc Firmware 2021-06-10 5.0 MEDIUM 7.5 HIGH
The DLink Router DIR-895L MFC v1.21b05 is vulnerable to credentials disclosure in telnet service through decompilation of firmware, that allows an unauthenticated attacker to gain access to the firmware and to extract sensitive data.
CVE-2021-27342 1 Dlink 2 Dir-842e, Dir-842e Firmware 2021-05-24 4.3 MEDIUM 5.9 MEDIUM

CVE-2021-20697 1 Dlink 2 Dap-1880ac, Dap-1880ac Firmware 2021-05-03 7.5 HIGH 9.8 CRITICAL
Missing authentication for critical function in DAP-1880AC firmware version 1.21 and earlier allows a remote attacker to login to the device as an authenticated user without the access privilege via unspecified vectors.
CVE-2013-1599 1 Dlink 34 Dcs-1100, Dcs-1100 Firmware, Dcs-1100l and 31 more 2021-04-27 10.0 HIGH 9.8 CRITICAL
A Command Injection vulnerability exists in the /var/www/cgi-bin/rtpd.cgi script in D-Link IP Cameras DCS-3411/3430 firmware 1.02, DCS-5605/5635 1.01, DCS-1100L/1130L 1.04, DCS-1100/1130 1.03, DCS-1100/1130 1.04_US, DCS-2102/2121 1.05_RU, DCS-3410 1.02, DCS-5230 1.02, DCS-5230L 1.02, DCS-6410 1.00, DCS-7410 1.00, DCS-7510 1.00, and WCS-1100 1.02, which could let a remote malicious user execute arbitrary commands through the camera’s web interface.
CVE-2017-8411 1 Dlink 2 Dcs-1130, Dcs-1130 Firmware 2021-04-26 9.3 HIGH 8.8 HIGH
An issue was discovered on D-Link DCS-1130 devices. The device provides a user with the capability of setting a SMB folder for the video clippings recorded by the device. It seems that the POST parameters passed in this request (to test if email credentials and hostname sent to the device work properly) result in being passed as commands to a "system" API in the function and thus result in command injection on the device. If the firmware version is dissected using binwalk tool, we obtain a cramfs-root archive which contains the filesystem set up on the device that contains all the binaries. The library "libmailutils.so" is the one that has the vulnerable function "sub_1FC4" that receives the values sent by the POST request. If we open this binary in IDA-pro we will notice that this follows an ARM little endian format. The function sub_1FC4 in IDA pro is identified to be receiving the values sent in the POST request and the value set in POST parameter "receiver1" is extracted in function "sub_15AC" which is then passed to the vulnerable system API call. The vulnerable library function is accessed in "cgibox" binary at address 0x00023BCC which calls the "Send_mail" function in "libmailutils.so" binary as shown below which results in the vulnerable POST parameter being passed to the library which results in the command injection issue.
CVE-2017-8404 1 Dlink 2 Dcs-1130, Dcs-1130 Firmware 2021-04-26 10.0 HIGH 9.8 CRITICAL

CVE-2017-8412 1 Dlink 4 Dcs-1100, Dcs-1100 Firmware, Dcs-1130 and 1 more 2021-04-26 5.8 MEDIUM 8.8 HIGH
An issue was discovered on D-Link DCS-1100 and DCS-1130 devices. The device has a custom binary called mp4ts under the /var/www/video folder. It seems that this binary dumps the HTTP VERB in the system logs. As a part of doing that it retrieves the HTTP VERB sent by the user and uses a vulnerable sprintf function at address 0x0000C3D4 in the function sub_C210 to copy the value into a string and then into a log file. Since there is no bounds check being performed on the environment variable at address 0x0000C360 this results in a stack overflow and overwrites the PC register allowing an attacker to execute buffer overflow or even a command injection attack.
CVE-2017-8410 1 Dlink 4 Dcs-1100, Dcs-1100 Firmware, Dcs-1130 and 1 more 2021-04-26 10.0 HIGH 9.8 CRITICAL
An issue was discovered on D-Link DCS-1100 and DCS-1130 devices. The binary rtspd in /sbin folder of the device handles all the rtsp connections received by the device. It seems that the binary performs a memcpy operation at address 0x00011E34 with the value sent in the "Authorization: Basic" RTSP header and stores it on the stack. The number of bytes to be copied are calculated based on the length of the string sent in the RTSP header by the client. As a result, memcpy copies more data then it can hold on stack and this results in corrupting the registers for the caller function sub_F6CC which results in memory corruption. The severity of this attack is enlarged by the fact that the same value is then copied on the stack in the function 0x00011378 and this allows to overflow the buffer allocated and thus control the PC register which will result in arbitrary code execution on the device.
CVE-2017-8406 1 Dlink 2 Dcs-1130, Dcs-1130 Firmware 2021-04-26 6.8 MEDIUM 8.8 HIGH
An issue was discovered on D-Link DCS-1130 devices. The device provides a crossdomain.xml file with no restrictions on who can access the webserver. This allows an hosted flash file on any domain to make calls to the device's webserver and pull any information that is stored on the device. In this case, user's credentials are stored in clear text on the device and can be pulled easily. It also seems that the device does not implement any cross-site scripting forgery protection mechanism which allows an attacker to trick a user who is logged in to the web management interface into executing a cross-site flashing attack on the user's browser and execute any action on the device provided by the web management interface which steals the credentials from tools_admin.cgi file's response and displays it inside a Textfield.
CVE-2013-1602 1 Dlink 34 Dcs-1100, Dcs-1100 Firmware, Dcs-1100l and 31 more 2021-04-26 5.0 MEDIUM 7.5 HIGH

CVE-2013-1603 1 Dlink 34 Dcs-1100, Dcs-1100 Firmware, Dcs-1100l and 31 more 2021-04-26 5.0 MEDIUM 5.3 MEDIUM
An Authentication vulnerability exists in D-LINK WCS-1100 1.02, TESCO DCS-2121 1.05_TESCO, TESCO DCS-2102 1.05_TESCO, DCS-7510 1.00, DCS-7410 1.00, DCS-6410 1.00, DCS-5635 1.01, DCS-5605 1.01, DCS-5230L 1.02, DCS-5230 1.02, DCS-3430 1.02, DCS-3411 1.02, DCS-3410 1.02, DCS-2121 1.06_FR, DCS-2121 1.06, DCS-2121 1.05_RU, DCS-2102 1.06_FR, DCS-2102 1.06, DCS-2102 1.05_RU, DCS-1130L 1.04, DCS-1130 1.04_US, DCS-1130 1.03, DCS-1100L 1.04, DCS-1100 1.04_US, and DCS-1100 1.03 due to hard-coded credentials that serve as a backdoor, which allows remote attackers to access the RTSP video stream.
CVE-2017-8417 1 Dlink 4 Dcs-1100, Dcs-1100 Firmware, Dcs-1130 and 1 more 2021-04-26 3.3 LOW 8.8 HIGH
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.
CVE-2017-8415 1 Dlink 4 Dcs-1100, Dcs-1100 Firmware, Dcs-1130 and 1 more 2021-04-26 10.0 HIGH 9.8 CRITICAL
An issue was discovered on D-Link DCS-1100 and DCS-1130 devices. The device has a custom telnet daemon as a part of the busybox and retrieves the password from the shadow file using the function getspnam at address 0x00053894. Then performs a crypt operation on the password retrieved from the user at address 0x000538E0 and performs a strcmp at address 0x00053908 to check if the password is correct or incorrect. However, the /etc/shadow file is a part of CRAM-FS filesystem which means that the user cannot change the password and hence a hardcoded hash in /etc/shadow is used to match the credentials provided by the user. This is a salted hash of the string "admin" and hence it acts as a password to the device which cannot be changed as the whole filesystem is read only.
CVE-2017-8409 1 Dlink 2 Dcs-1130, Dcs-1130 Firmware 2021-04-23 5.0 MEDIUM 7.5 HIGH
An issue was discovered on D-Link DCS-1130 devices. The device requires that a user logging to the device to provide a username and password. However, the device does not enforce the same restriction on a specific URL thereby allowing any attacker in possession of that to view the live video feed. The severity of this attack is enlarged by the fact that there more than 100,000 D-Link devices out there.
CVE-2017-8405 1 Dlink 4 Dcs-1100, Dcs-1100 Firmware, Dcs-1130 and 1 more 2021-04-23 5.0 MEDIUM 7.5 HIGH
An issue was discovered on D-Link DCS-1130 and DCS-1100 devices. The binary rtspd in /sbin folder of the device handles all the rtsp connections received by the device. It seems that the binary loads at address 0x00012CF4 a flag called "Authenticate" that indicates whether a user should be authenticated or not before allowing access to the video feed. By default, the value for this flag is zero and can be set/unset using the HTTP interface and network settings tab as shown below. The device requires that a user logging to the HTTP management interface of the device to provide a valid username and password. However, the device does not enforce the same restriction by default on RTSP URL due to the checkbox unchecked by default, thereby allowing any attacker in possession of external IP address of the camera to view the live video feed. The severity of this attack is enlarged by the fact that there more than 100,000 D-Link devices out there.
CVE-2017-8407 1 Dlink 2 Dcs-1130, Dcs-1130 Firmware 2021-04-23 6.8 MEDIUM 8.8 HIGH
An issue was discovered on D-Link DCS-1130 devices. The device provides a user with the capability of changing the administrative password for the web management interface. It seems that the device does not implement any cross-site request forgery protection mechanism which allows an attacker to trick a user who is logged in to the web management interface to change the user's password.
CVE-2019-14338 1 Dlink 4 6600-ap, 6600-ap Firmware, Dwl-3600ap and 1 more 2021-04-23 4.3 MEDIUM 6.1 MEDIUM
