A critical unauthenticated Remote Code Execution (RCE) vulnerability has been identified in D-Link’s DSL-3788 routers, specifically hardware revisions Ax/Bx running firmware version v1.01R1B036_EU_EN or below.
This flaw enables attackers to gain full remote access to the device, posing significant security and privacy risks.
