okhttp: information disclosure via improperly used cryptographic function

In verifyHostName of OkHostnameVerifier.java, there is a possible way to accept a certificate for the wrong domain due to improperly used crypto. This could lead to remote information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation.Produc...

Improper Certificate Validation

Overview com.squareup.okhttp3:okhttp is a HTTP & HTTP/2 client for Android and Java applications Affected versions of this package are vulnerable to Improper Certificate Validation via the verifyHostName function in OkHostnameVerifier.java. An attacker can gain unauthorized access to sensitive...

ALPACA is an application layer protocol content confusion attack exploiting TLS servers implementing different protocols but using compatible certificates such as multi-domain or wildcard certificates. A MiTM attacker having access to victim's traffic at the TCP/IP layer can redirect traffic from one subdomain to another resulting in a valid TLS session. This breaks the authentication of TLS and cross-protocol attacks may be possible where the behavior of one protocol service may compromise the other at the application layer.

Why Web Browser Padlocks Shouldn't Be Trusted

For years, Apple, Firefox, Google and Microsoft relentlessly made the point that in order to avoid rogue sites you must make sure your browser “padlock” is either locked, green or is otherwise indicating a site as being “secure.” Now, cybersecurity firms are stressing that those padlocks are not...
