CVE-2020-1472

A flaw was found in the Microsoft Windows Netlogon Remote Protocol MS-NRPC, where it reuses a known, static, zero-value initialization vector IV in AES-CFB8 mode. This flaw allows an unauthenticated attacker to impersonate a domain-joined computer, including a domain controller, and possibly obta...

Hardcoded Initialization Vector in parsel

All versions of parsel have a default hardcoded initialization vector. In cases where the IV is not provided, the package defaults to a hardcoded IV which renders the cipher vulnerable to chosen plaintext attacks. Recommendation The package is deprecated and will not be updated. Consider using an...
