Which tool can be used to perform session splicing attacks?

• A. Nessus
• B. Whisker
• C. Nmap
• D. Metasploit

Answer: (B)

Testing for session management weaknesses, including session splicing, focuses on how a web application handles the session ID and cookies. Session splicing involves manipulating or reusing a session identifier across requests to impersonate a user or join sessions, exploiting flaws in how the application tracks and validates sessions.

Whisker is a web vulnerability scanner that targets web server and CGI-related weaknesses, including how sessions are managed. It can probe for misconfigurations and vulnerable handling of session IDs and cookies, such as insecure transmission, weak or predictable tokens, or improper cookie attributes, which can enable session splicing or hijacking. This makes it the most suitable tool among the options for detecting session-splicing opportunities.

Nessus is a broad vulnerability scanner, Nmap primarily does network discovery and port scanning, and Metasploit focuses on exploitation. While useful in many contexts, they don’t specialize in testing web session management weaknesses the way Whisker does, which is why Whisker is the best fit for this specific attack vector.
