CVE-2025-4858Public exploitNetwork attack vector

Authenticated script execution via unsanitized harp_mac input

Published May 18, 2025 · Updated May 19, 2025

Cross-site scripting in D-Link DAP-2695 120b36r137_ALL_en_20210528 allows remote authenticated users to execute script via harp_mac. The ARP Spoofing Prevention page fails to neutralize the attacker-controlled harp_mac value before /adv_arpspoofing.php renders it. Administrative privileges and victim interaction are required, limiting the consequence to script execution in the victim's browser context.
