🕵️ **Impact**: Steal cookies, hijack sessions, or redirect users.
📊 **Data**: Client-side data compromise via XSS.

Question 5

Is exploitation threshold high? (Auth/Config)

Accepted Answer

🔓 **Auth**: Likely No Authentication required.
⚙️ **Config**: Exploits via crafted links/URLs.
📉 **Threshold**: Low. Just need to trick a user to click.

Question 6

Is there a public Exp? (PoC/Wild Exploitation)

Accepted Answer

📢 **Public Exp**: Yes.
📜 **Evidence**: Bugtraq mailing list (SNS Advisory No.49) and Cisco advisory confirm exploitation possibility.
🌐 **Wild**: Likely via social engineering links.

Question 7

How to self-check? (Features/Scanning)

Accepted Answer

🔍 **Check**: Look for IIS redirect responses.
