Title: Rightfax Webclient Predictable Session Number Vulnerability
Severity: MODERATE
Description:
The RightFax server uses a session ID to track users' connections to web-based fax services. This ID is predictable and legitimate session IDs can be generated arbitrarily. It is included in the URL, and by generating a session ID in use by another user it is possible to hijack their connection. This leads to the ability to send and read faxes as that user.
Affected Products:
- AVT Rightfax 5.2.0
