The encrypted e-mail feature in IBM Lotus Notes Traveler before 8.5.0.2 sends unencrypted messages when the feature is used without uploading a Notes ID file, which makes it easier for remote attackers to obtain sensitive information by sniffing the network.
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.
