|Product:||PGP Universal Web Messenger|
|Affected version:||All prior to 3.3.2|
|Reported by:||Richard O’Donnell|
Authenticated Web Messenger users are able to view other users email messages, by following these steps:

2) View the list of sent emails
3) Click on any of the sent emails
4) Click on the `Print’ option and then copy the URL from the page that appears.
The URL will look similar to this:
5) Using this URL, brute-force the following part of the `sid’ parameter:
6) Upon identifying a valid value, access to the corresponding email message will be obtained.
Although there is a risk of obtaining unauthorised access to another users email, the likelihood of successfully brute-forcing a correct `sid’ value is considered low, due to its complexity.
It is also noted that encryption of messages was not enabled when this issue was identified and no additional testing was performed with this option enabled.
This allows users to read e-mails of other users
Exploit code is not required.
