CVE-2023-31582
Public on
Last Modified:
Description
A flaw was found in Jose4J which allows a malicious user or internal person to erroneously set a low iteration count of 1000 or less to secure the Json Web Token. This could apply to lack of entropy and leave the system less secure.
Statement
This flaw would require manually setting of the number of iterations under 1000 for Json Web Encryption, therefore, a malicious user would need previous access to modify it. Also, a user would still be able to set the variable incorrectly and make the environment less secure for JWE. This is currently rated as a moderate impact.
Mitigation
No mitigation is currently available for this flaw.
