CWE-203  (opens in a new tab)

How to fix?

There is no fixed version for org.webjars.bower:jsrsasign.

Overview

org.webjars.bower:jsrsasign is a free pure JavaScript cryptographic library.

Affected versions of this package are vulnerable to Observable Discrepancy via the RSA PKCS#1.5 or RSAOAEP decryption process. An attacker can decrypt ciphertexts by exploiting the Marvin security flaw. Exploiting this vulnerability requires the attacker to have access to a large number of ciphertexts encrypted with the same key.

Workaround

The vulnerability can be mitigated by finding and replacing RSA and RSAOAEP decryption with another crypto library.
