Issue
The Thycotic Password Manager Secret Server iOS application does not validate the SSL certificate it receives when connecting to a secure site.
Impact
An attacker could perform a man in the middle attack by presenting a bogus SSL certificate which the application will accept silently.
Usernames, passwords and sensitive information could be captured by an attacker without the user's knowledge.
