VAR-202511-0322

Vulnerability from variot - Updated: 2025-11-20 23:34

A vulnerability was found in D-Link DIR-816L 2_06_b09_beta. This vulnerability affects the function scandir_main of the file /portal/__ajax_exporer.sgi. The manipulation of the argument en results in stack-based buffer overflow. The attack may be performed from remote. The exploit has been made public and could be used. This vulnerability only affects products that are no longer supported by the maintainer. The DIR-816L is a wireless router product manufactured by D-Link.

Version 2_06_b09_beta of the D-Link DIR-816L contains a stack buffer overflow vulnerability. This vulnerability stems from a failure to properly validate the input length when manipulating the en parameter of the scandir_main function in the /portal/__ajax_exporer.sgi file. An attacker could exploit this vulnerability to trigger a stack overflow by remotely sending specially crafted data, thereby executing arbitrary code or causing service interruption
