CVE-2020-7805Network attack vector

Unauthenticated OS command execution via command injection

Published May 7, 2020 · Updated Aug 4, 2024

OS command injection in Infomark Slim Egg IML500 and IML520 affected firmware allows remote attackers to execute arbitrary OS commands. The public record does not identify the request parameter, interface, or firmware routine that passes attacker-controlled input to an operating-system command. No authentication or user interaction is required; successful exploitation permits command execution on the mobile router and can expose or alter data or interrupt service.
