Name of the Vulnerable Software and Affected Versions:
D-Link DSL-2730U version IN 1.02
D-Link DSL-2750U version SEA 1.04
D-Link DSL-2750E version SEA 1.07
Description:
A path traversal vulnerability exists in the web management interface of D-Link ADSL routers due to insufficient input validation on the `getpage` parameter within the "/cgi-bin/webproc" CGI script. This flaw allows an unauthenticated remote attacker to perform path traversal attacks by supplying crafted requests, enabling arbitrary file read on the affected device.
Recommendations:
For D-Link DSL-2730U version IN 1.02, consider disabling the `/cgi-bin/webproc` CGI script until a patch is available.
For D-Link DSL-2750U version SEA 1.04, restrict access to the `getpage` parameter to minimize the risk of exploitation.
For D-Link DSL-2750E version SEA 1.07, avoid using the `getpage` parameter in the affected API endpoint until the issue is resolved.
