Kaspersky Safe Browser iOS Application - MITM SSL Certificate
Vulnerability (CVE-2016-6231)


"Stay safe from malicious links, suspicious content and identity theft
while you surfing the Internet."

"Our Safe Browser covers the original iPhone & iPad web browser and
detects & blocks phishing sites that can steal your money & your
account details, eliminates unwanted content & notifies about spam
links - for you to surf the web without frontiersâ?¦ safely."

"You will get:

- Advanced Anti-Phishing to effectively block fake websites
- Proactive detection of fraudulent links / URLs - powered by the cloud
- Content filtering to choose & block specific categories of unwanted info
- Safe internet browsing across Google, Bing, Yandex and Yahoo search engines"



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


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.
