Description
Attacks against an Enterprise Voice, Video, and Messaging Session Manager may include denial of service (DoS), replay attacks, or cross-site scripting. A replay attack may enable an unauthorized user to gain access to the application. Authentication sessions between the authenticator and the application validating the user credentials must not be vulnerable to a replay attack. An authentication process resists replay attacks if it is impractical to achieve a successful authentication by recording and replaying a previous authentication message. Techniques used to address this include protocols using nonces (e.g., numbers generated for a specific one time use) or challenges (e.g., TLS, WS_Security). Additional techniques include time-synchronous or challenge-response one-time authenticators. A cross-site scripting vulnerability was demonstrated on a SIP-based IP phone by adding scripting code to the "From" field in the SIP invite. Upon receiving the invite, the embedded code was executed by the IP phone embedded web server to download additional malicious code.
