D-Link DIR-601 A1 1.02NA devices do not require the old password for a password change, which occurs in cleartext.

D-Link DCS cameras have a weak/insecure CrossDomain.XML file that allows sites hosting malicious Flash objects to access and/or change the device's settings via a CSRF attack. This is because of the 'allow-access-from domain' child element set to *, thus accepting requests from any domain. If a victim logged into the camera's web console visits a malicious site hosting a malicious Flash file from another Browser tab, the malicious Flash file then can send requests to the victim's DCS series Camera without knowing the credentials. An attacker can host a malicious Flash file that can retrieve Live Feeds or information from the victim's DCS series Camera, add new admin users, or make other changes to the device. Known affected devices are DCS-933L with firmware before 1.13.05, DCS-5030L, DCS-5020L, DCS-2530L, DCS-2630L, DCS-930L, DCS-932L, and DCS-932LB1.

D-Link DIR-615 HW: T1 FW:20.09 is vulnerable to Cross-Site Request Forgery (CSRF) vulnerability. This enables an attacker to perform an unwanted action on a wireless router for which the user/admin is currently authenticated, as demonstrated by changing the Security option from WPA2 to None, or changing the hiddenSSID parameter, SSID parameter, or a security-option password.

D-Link DCS-936L devices with firmware before 1.05.07 have an inadequate CSRF protection mechanism that requires the device's IP address to be a substring of the HTTP Referer header.

Cross Site Request Forgery (CSRF) on D-Link DSL-2730U C1 IN_1.00 devices allows remote attackers to change the DNS or firewall configuration or any password.

CSRF exists on D-Link DIR-600M Rev. Cx devices before v3.05ENB01_beta_20170306. This can be used to bypass authentication and insert XSS sequences or possibly have unspecified other impact.

D-Link DIR-601 B1 2.00NA devices have CSRF because no anti-CSRF token is implemented. A remote attacker could exploit this in conjunction with CVE-2019-16327 to enable remote router management and device compromise. NOTE: this is an end-of-life product.

D-Link DIR-655 C devices before 3.02B05 BETA03 allow CSRF for the entire management console.

Multiple cross-site request forgery (CSRF) vulnerabilities in D-Link DAP 1150 with firmware 1.2.94 allow remote attackers to hijack the authentication of administrators for requests that (1) enable or (2) disable the DMZ in the Firewall/DMZ section via a request to index.cgi or (3) add, (4) modify, or (5) delete URL-filter settings in the Control/URL-filter section via a request to index.cgi, as demonstrated by adding a rule that blocks access to google.com.

D-Link DGS-1100 devices with Rev.B firmware 1.01.018 have a hardcoded SSL private key, which allows man-in-the-middle attackers to spoof devices by hijacking an HTTPS session.

Multiple cross-site request forgery (CSRF) vulnerabilities in the D-Link DIR-816L Wireless Router with firmware before 2.06.B09_BETA allow remote attackers to hijack the authentication of administrators for requests that (1) change the admin password, (2) change the network policy, or (3) possibly have other unspecified impact via crafted requests to hedwig.cgi and pigwidgeon.cgi.

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.

On the D-Link DIR-615 before v20.12PTb04, if a victim logged in to the Router's Web Interface visits a malicious site from another Browser tab, the malicious site then can send requests to the victim's Router without knowing the credentials (CSRF). An attacker can host a page that sends a POST request to Form2File.htm that tries to upload Firmware to victim's Router. This causes the router to reboot/crash resulting in Denial of Service. An attacker may succeed in uploading malicious Firmware.

CSRF exists on D-Link DIR-868L devices, leading to (for example) a change to the Admin password. hedwig.cgi and pigwidgeon.cgi are two of the affected components.

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.

D-Link DIR-100 4.03B07: cli.cgi CSRF

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.

D-Link DIR-853 A1 FW1.20B07 was discovered to contain a stack-based buffer overflow vulnerability via the Password parameter in the SetQuickVPNSettings module.

On the D-Link DIR-615 before v20.12PTb04, once authenticated, this device identifies the user based on the IP address of his machine. By spoofing the IP address belonging to the victim's host, an attacker might be able to take over the administrative session without being prompted for authentication credentials. An attacker can get the victim's and router's IP addresses by simply sniffing the network traffic. Moreover, if the victim has web access enabled on his router and is accessing the web interface from a different network that is behind the NAT/Proxy, an attacker can sniff the network traffic to know the public IP address of the victim's router and take over his session as he won't be prompted for credentials.

D-Link DIR-879 v105A1 is vulnerable to Authentication Bypass via phpcgi.

D-Link DIR-890L FW1.10 A1 is vulnerable to Authentication bypass.

/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.
