HIGHCyberArk Credential Provider < 12.1 - Information Disclosure via Inadequate Encryption
Title source: llmExploitation Summary
EIP tracks 1 public exploit for CVE-2021-31796. PoCs published by unmanarc.
AI-analyzed exploit summary This repository contains a functional exploit tool for CVE-2021-31796, which targets a cryptographic weakness in CyberArk's credential storage. The tool decodes credential files by reversing the AES-256-CBC encryption scheme used, leveraging insufficient effective key space due to predictable key derivation from the 'AdditionalInformation' field.
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.
