This vulnerability affects unknown code of the file /devinfo of the component HTTP GET Request Handler. The manipulation of the argument area with the input notice|net|version leads to information disclosure. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used. VDB-251542 is the identifier assigned to this vulnerability.

Buffer Overflow Vulnerability in D-Link DIR-825 v1.33.0.44ebdd4-embedded and below allows attacker to execute arbitrary code via the GetConfig method to the /CPE endpoint.

An issue was discovered on D-Link DIR-825 Rev.B 2.10 devices. There is a stack-based buffer overflow in the httpd binary. It allows an authenticated user to execute arbitrary code via a POST to ntpsync.cgi with a sufficiently long parameter ntpserver.

An issue was discovered on D-Link DIR-825 Rev.B 2.10 devices. They allow remote attackers to execute arbitrary commands via the dnsqueryname parameter in a dnsquery.cgi POST request. TRENDnet TEW-632BRP 1.010B32 is also affected.

An issue was discovered on D-Link DIR-825 Rev.B 2.10 devices. They allow remote attackers to execute arbitrary commands via the date parameter in a systemtime.cgi POST request. TRENDnet TEW-632BRP 1.010B32 is also affected.

An issue was discovered on D-Link DIR-825 Rev.B 2.10 devices. They allow remote attackers to execute arbitrary commands via the wpsstaenrolleepin parameter in a setstaenrolleepin.cgi POST request. TRENDnet TEW-632BRP 1.010B32 is also affected.

In the "webupg" binary of D-Link DIR-825 G1, attackers can bypass authentication through parameters "autoupgrade.asp", and perform functions such as downloading configuration files and updating firmware without authorization.

In the "webupg" binary of D-Link DIR-825 G1, because of the lack of parameter verification, attackers can use "cmd" parameters to execute arbitrary system commands after obtaining authorization.

UNSUPPORTED WHEN ASSIGNED Null Pointer Dereference vulnerability in D-Link DIR-825 2.10b02, which could let a remote malicious user cause a denial of service. The vulnerability could be triggered by sending an HTTP request with URL /vctwan; the sbin/httpd would invoke the strchr function and take NULL as a first argument, which finally leads to the segmentation fault. NOTE: The DIR-825 and all hardware revisions is considered End of Life and as such this issue will not be patched.

D-LINK DIR-825 AC1200 R2 is vulnerable to Directory Traversal. An attacker could use the "../../../../" setting of the FTP server folder to set the router's root folder for FTP access. This allows you to access the entire router file system via the FTP server.
