When LDAP connection is activated in Teedy versions between 1.9 to 1.12, the username field of the login form is vulnerable to LDAP injection. Due to improper sanitization of user input, an unauthenticated attacker is then able to perform various malicious actions, such as creating arbitrary accounts and spraying passwords.
Teedy v1.11 has a vulnerability in its text editor that allows events
to be executed in HTML tags that an attacker could manipulate. Thanks
to this, it is possible to execute malicious JavaScript in the webapp.
