CVE-2018-7739: Antsle Antman

Critical severity, CVSS 9.8. EPSS: 53.2% chance of exploitation in the next 30 days.

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.

Affected products

• Antsle Antman: up to and including 0.9.0c
