Malicious-site redirection via unvalidated redir parameter
Published Apr 8, 2025 · Updated Apr 8, 2026
Open redirect in Smartdevth Advanced Advertising System 1.3.1 and earlier allows remote attackers to send users to malicious sites. The shortcode redirect path accepts the redir request parameter as a destination without checking whether it points to a trusted site. Exploitation requires an attacker to persuade a user to activate a crafted request; the result is browser redirection rather than direct site compromise.
