Patches

Vulnerability mechanics

Root cause

"Missing anti-framing headers (X-Frame-Options) allow the Joomla! page to be rendered inside a third-party iframe."

Attack vector

An attacker crafts a malicious web page that embeds the Joomla! site in an invisible or transparent iframe. Because Joomla! does not prevent page rendering inside a frame [CWE-20], the victim can be tricked into clicking on elements of the Joomla! interface (e.g., admin buttons) while believing they are interacting with the attacker's page. This clickjacking attack requires no authentication from the attacker; the victim must be logged into the Joomla! site for the framed actions to be meaningful [ref_id=1].

Affected code

The advisory does not specify a particular file or function; it describes a general lack of anti-framing headers (such as X-Frame-Options) in Joomla! 1.6.x before 1.6.2 [ref_id=1].

What the fix does

The advisory does not include a patch diff. The remediation for clickjacking is to add an X-Frame-Options response header (e.g., SAMEORIGIN) or a frame-busting JavaScript snippet to prevent the page from being rendered inside a third-party frame. Joomla! 1.6.2 presumably introduced such a protection, but the exact code change is not shown in the available references [ref_id=1].

Preconditions

  • authThe victim must be logged into the Joomla! site for the framed click to have an effect (e.g., performing an admin action).
  • inputThe attacker must host a crafted HTML page that embeds the Joomla! site in an iframe.
  • configThe victim's browser must not have built-in clickjacking protections that block the attack.
