CVE-2025-52222

Description

D-Link DI-8003 v16.07.26A1, DI-8500 v16.07.26A1; DI-8003G v17.12.21A1, DI-8200G v17.12.20A1, DI-8200 v16.07.26A1, DI-8400 v16.07.26A1, DI-8004w v16.07.26A1, DI-8100 v16.07.26A1, and DI-8100G v17.12.20A1 were discovered to contain a buffer overflow via the rd_en, rd_auth, rd_acct, http_hadmin, http_hadminpwd, rd_key, and rd_ip parameters in the radius_asp function. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted request.
