Summary

Advantech EKI-1524, EKI-1522, and EKI-1521 devices running versions up to 1.21 are susceptible to a Stored Cross-Site Scripting vulnerability. This issue arises when an authenticated user inputs malicious scripts into the device name field via the web interface. Successful exploitation allows attackers to execute harmful scripts in the context of users viewing the device's information, potentially leading to further security breaches and data compromise.

Affected Version(s)

EKI-1521 0 <= 1.21

EKI-1522 0 <= 1.21

EKI-1524 0 <= 1.21

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
