A path traversal (directory traversal) vulnerability in D-Link DSR series routers allows unauthenticated remote attackers to manipulate input parameters used for file or directory path resolution (e.g., via sequences such as “../”). Successful exploitation may allow access to files outside of the intended directory, potentially exposing sensitive system or configuration files. The issue results from insufficient validation or sanitization of user-supplied input. Affected Products include: DSR-150, DSR-150N, and DSR-250N v1.09B32_WW.
