CVE-2023-46233, also known as a vulnerability in crypto-js, affects versions prior to 4.2.0 of the JavaScript library. This vulnerability arises from the fact that crypto-js PBKDF2 defaults to using the insecure SHA1 algorithm and has a low default iteration count of 1,000. This makes it around 1,000 times weaker than originally specified in 1993 and significantly weaker than current industry standards. The impact of this vulnerability is high if it is used to protect passwords or generate signatures. However, version 4.2.0 includes a patch for this issue. As a temporary workaround, users can configure crypto-js to use SHA256 with at least 250,000 iterations. The potential danger posed by this vulnerability lies in the compromise of sensitive information and the potential for unauthorized access to an organization's systems or accounts if not remediated promptly and appropriately.
