Admin-page disruption via unchecked language parameter
Published May 13, 2026 · Updated May 13, 2026
Improper input validation in affected ELECOM WAB-BE access points allows remote attackers to break the browser admin page. The management interface accepts an unchecked language parameter triggered by a malicious webpage and leaves its administrative page unusable in the logged-in user’s browser. Exploitation requires an administrator to remain logged in and visit attacker-controlled content; the reported impact is limited to loss of browser-based administrative access.
