Title: ICA Weak Encryption Vulnerability
Severity: HIGH
Description:
The ICA protocol uses a simple XOR-based encryption algorthm to protect user credentials while stored or in transit. This encryption can be easily broken, meaning that anyone sniffing the connection can obtain user access to the server.
The ICA protocol, developed by Citrix, is used in Citrix server products such as WinFrame and MetaFrame and possibly others, and in Citrix and third party clients for those products.
Affected Products:
- Citrix MetaFrame for Unix 1.0.0
- Citrix MetaFrame for Windows 2000 1.8.0
- Citrix MetaFrame for Windows NT 4.0 TSE 1.8.0
- Citrix WinFrame for Windows NT 3.5 1.8.0
