CVE-2026-4354 Details
Description
A vulnerability was identified in TRENDnet TEW-824DRU 1.010B01/1.04B01. The impacted element is the function sub_420A78 of the file apply_sec.cgi of the component Web Interface. Such manipulation of the argument Language leads to cross site scripting. It is possible to launch the attack remotely. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.
A stored cross-site scripting vulnerability has been identified in the TRENDnet TEW-824DRU router, specifically in the web interface component 'apply_sec.cgi', within the 'sub_420A78' function. This vulnerability affects firmware versions 1.010B01 and 1.04B01. The issue arises from improper handling of the 'language' parameter, which allows remote attackers to inject arbitrary web scripts or HTML. Once injected, the malicious script is executed in the context of the user, potentially leading to a denial-of-service condition on the web interface.
