> * *Vulnerability Description:* In “src/plugin/protocol-httpclient/src/java/org/apache/nutch/protocol/httpclient/DummyX509TrustManager.java”
overridden TrustManager methods (i.e. checkClientTrusted and checkServerTrusted) do not have
validation logic for certificates.
>  * *Reason it’s vulnerable:* It is vulnerable because DummyX509TrustManager implements
X509TrustManager and it overrides the standard TrustManager methods (i.e. checkClientTrusted
and checkServerTrusted) to do nothing but returning hard-coded *true*. Certificate validation
is expected to be handled by these methods. Doing nothing means no verification.
>  * *Suggested Fix:* Adding necessary certificate verification logic in the overridden
methods.
>  * *Feedback:* Please select any of the options down below to help us get an idea about
how you felt about the suggestion -
>  # Liked it and will make the suggested changes
>  # Liked it but happy with the existing version
>  # Didn’t find the suggestion helpful
