Vulnerability CVE-2018-7739


Published: 2018-03-06   Modified: 2018-03-07

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.

Type:

CWE-20

(Improper Input Validation)
