IBM WebSphere Advanced Server Edition 4.0.4 uses a weak encryption algorithm (XOR and base64 encoding), which allows local users to decrypt passwords when the configuration file is exported to XML.
Category : Cryptographic Issues Weaknesses in this category are related to the design and implementation of data confidentiality and integrity. Frequently these deal with the use of encoding techniques, encryption libraries, and hashing algorithms. The weaknesses in this category could lead to a degradation of the quality data if they are not addressed.
