CWE-20  (opens in a new tab)

How to fix?

Upgrade org.bouncycastle:bcprov-jdk15on to version 1.56 or higher.

Overview

org.bouncycastle:bcprov-jdk15on is a Java implementation of cryptographic algorithms.

Affected versions of this package are vulnerable to Insufficient Validation. The DSA does not fully validate ASN.1 encoding of signature on verification. It is possible to inject extra elements in the sequence making up the signature and still have it validate, which in some cases may allow the introduction of invisible data into a signed structure.
