Name of the Vulnerable Software and Affected Versions: D-Link DAP-2020 version 1.01rc001 Description: This issue allows network-adjacent attackers to disclose sensitive information on affected installations. Authentication is not required to exploit this issue. The specific flaw exists within the handling of the `getpage` parameter provided to the "webproc" endpoint. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this issue to disclose information in the context of root. Recommendations: For D-Link DAP-2020 version 1.01rc001, as a temporary workaround, consider restricting access to the "webproc" endpoint until a patch is available. Avoid using the `getpage` parameter in the affected endpoint until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this issue.

Recommendations: For D-Link DAP-2020 version 1.01rc001, consider restricting access to CGI scripts until a patch is available. As a temporary workaround, avoid using the `errorpage` parameter in requests to minimize the risk of exploitation.

This issue allows network-adjacent attackers to disclose sensitive information on affected installations of D-Link routers. Authentication is not required to exploit this issue. 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 issue to disclose stored credentials, leading to further compromise.

This issue allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link routers. Authentication is not required to exploit this issue. 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 issue to execute code in the context of the web server.

This issue allows network-adjacent attackers to execute arbitrary code on affected installations. Authentication is not required to exploit this issue. The specific flaw exists within the HNAP service, which listens on TCP port 80 by default. When parsing the `Authorization` request header, the process does not properly validate a user-supplied string before using it to execute a system call. An attacker can leverage this issue to execute code in the context of the device.

This issue allows network-adjacent attackers to execute arbitrary code on affected installations. Authentication is not required to exploit this issue. The specific flaw exists within the uhttpd service, which listens on TCP port 80 by default. The issue results from incorrect string matching logic when accessing protected pages. An attacker can leverage this issue to escalate privileges and execute code in the context of the device.

The issue is related to a buffer overflow on the stack in the webproc getpage scenario of the D-Link DAP-2020 Wi-Fi access point's firmware. This can be exploited by network-adjacent attackers to execute arbitrary code on affected installations without requiring authentication. The flaw exists in the processing of CGI scripts, specifically when parsing the `getpage` parameter, where the length of user-supplied data is not properly validated before being copied to a fixed-length stack-based buffer. This allows an attacker to execute code in the context of root.

This issue allows network-adjacent attackers to bypass authentication on affected installations. The specific flaw exists within the processing of HNAP `GetCAPTCHAsetting` requests, resulting from the lack of proper handling of sessions. An attacker can leverage this to execute arbitrary code in the context of the device.

This issue allows network-adjacent attackers to execute arbitrary code on affected devices. Although authentication is required, the existing authentication mechanism can be bypassed. The flaw exists within the HNAP service, which listens on TCP port 80 by default. When parsing the `SOAPAction` header, the process does not properly validate a user-supplied string before using it to execute a system call. An attacker can leverage this to execute code in the context of the device.

The issue is related to the implementation of the HNAP protocol in the firmware of D-Link routers, which allows an attacker to bypass authentication procedures by utilizing an alternative path or channel when handling HTTP requests that include the string ?GetCAPTCHAsetting. This can enable a remote attacker to bypass security restrictions, escalate privileges, or execute arbitrary code. The flaw exists within the handling of HNAP requests due to incorrect string matching logic when accessing protected pages.

The issue allows Directory Traversal for reading arbitrary files via the `com.tp link.eap.web.portal.PortalController.getAdvertiseFile` function in the `/opt/tplink/EAPController/lib/eap-web-3.2.6.jar` file. This can be exploited through the `getAdvertiseFile` function.
