Use of a Broken or Risky Cryptographic Algorithm

Summary

The package crypto-js is a JavaScript library of crypto standards. In versions prior to 4.2.0, crypto-js PBKDF2 is 1,000 times weaker than originally specified in 1993, and at least 1,300,000 times weaker than the current industry standard. This is because it both defaults to SHA1, a cryptographic hash algorithm considered insecure since at least 2005 and defaults to one single iteration, a "strength" or "difficulty" value specified at 1,000 when specified in 1993. PBKDF2 relies on the iteration count as a countermeasure to preimage and collision attacks. If used to protect passwords, the impact is high. If used to generate signatures, the impact is high. As a workaround, configure crypto-js to use SHA256 with at least 250,000 iterations.
