Detailsinfo

A vulnerability was found in crypto-js up to 3.2.0 on Node.js (JavaScript Library). It has been classified as problematic. Affected is some unknown processing. The manipulation with an unknown input leads to a entropy vulnerability. CWE is classifying the issue as CWE-332. The lack of entropy available for, or used by, a Pseudo-Random Number Generator (PRNG) can be a stability and security threat. This is going to have an impact on confidentiality. CVE summarizes:

The crypto-js package before 3.2.1 for Node.js generates random numbers by concatenating the string "0." with an integer, which makes the output more predictable than necessary.

The weakness was released 06/12/2023 as 254. The advisory is shared for download at github.com. This vulnerability is traded as CVE-2020-36732 since 06/12/2023. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1600.001.
