Title: Lotus Notes Client Unencrypted Sent Mail Vulnerability
Severity: LOW
Description:
Lotus Notes Client has a built-in feature that automatically encrypts email sent to other Lotus Notes users. Typically Lotus Notes sends two copies of outgoing email, one to the email recipient and one to the 'Sent Mail' folder which is normally located on the Domino mail server. Both copies should be encrypted. However, under certain circumstances, the copy sent to the 'Sent Mail' folder could be transmitted in plaintext form.
If the forward slash "/" convention is used as a path separator when specifying a mail file rather than a backward slash "\", the unencrypted email vulnerability will result. If a malicious third party could eavesdrop on the network traffic between the client and server or have access to the 'Sent Mail' folder itself, they may possibly intercept confidential information in cleartext.
Affected Products:
- Lotus Notes Client 4.5.0
