CVE-2018-7739: Input Validation
First published: Tue Mar 06 2018(Updated: )
antsle antman before 0.9.1a allows remote attackers to bypass authentication via invalid characters in the username and password parameters, as demonstrated by a username=>&password=%0a string to the /login URI. This allows obtaining root permissions within the web management console, because the login process uses Java's ProcessBuilder class and a bash script called antsle-auth with insufficient input validation.
