CVE-2023-46233

Summary

CVE-2023-46233 is a vulnerability affecting the crypto-js library before version 4.2.0. Contrary to the original specifications in 1993, crypto-js PBKDF2 function uses SHA1, an outdated and insecure cryptographic hash algorithm, and defaults to a single iteration, significantly weakening its security. This issue makes crypto-js 1,300,000 times weaker than current industry standards. PBKDF2's reliance on iteration count as a countermeasure to preimage and collision attacks is compromised, posing high risks for password protection and digital signature generation. Version 4.2.0 includes a patch, and as a temporary solution, users can configure crypto-js to employ SHA256 with at least 250,000 iterations.
