Padding Oracle Attack

Description

A vulnerability arises when an attacker can manipulate the padding on an encrypted string, inducing an error message that reveals a ‘padding oracle’ weakness. This issue affects applications and frameworks utilizing encryption poorly, such as certain ASP.net versions. An attacker might exploit this to decrypt data and recover encryption keys, compromising sensitive information.

Recommendation

Upgrade or modify scripts to properly validate encrypted data before attempting decryption.
