CVE-2021-31796
An inadequate encryption vulnerability discovered in CyberArk Credential Provider before 12.1 may lead to Information Disclosure.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.76%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
An inadequate encryption vulnerability discovered in CyberArk Credential Provider before 12.1 may lead to Information Disclosure. An attacker may realistically have enough information that the number of possible keys (for a credential file) is only one, and the number is usually not higher than 2^36.
