CVE-2018-7739 Information

Description

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.
