Issue

The Kaspersky Safe Browser iOS application (version 1.6.0 and below),
does not validate SSL certificates it receives when connecting to
secure sites.

Impact

An attacker who can perform a man in the middle attack may present a
bogus SSL certificate for a secure site which the application will
accept silently. Usernames, passwords and sensitive information could
be captured by an attacker without the user's knowledge.
