Description

tarteaucitron.js allows url scheme injection via unfiltered inputs

A vulnerability was identified in tarteaucitron.js, allowing a user with high privileges (access to the site's source code or a CMS plugin) to enter a URL containing an insecure scheme such as javascript:alert(). Before the fix, URL validation was insufficient, which could allow arbitrary JavaScript execution if a user clicked on a malicious link.

Impact

An attacker with high privileges could insert a link exploiting an insecure URL scheme, leading to:

  • Execution of arbitrary JavaScript code
  • Theft of sensitive data through phishing attacks
  • Modification of the user interface behavior

Fix https://github.com/AmauriC/tarteaucitron.js/commit/2fa1e01023bce2e4b813200600bb1619d56ceb02

The issue was resolved by enforcing strict URL validation, ensuring that they start with http:// or https:// before being used.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs administrative privileges on the target. A user must be tricked into taking some action. The scope is changed, meaning a successful attack can affect components beyond the vulnerable one. Rated impact: confidentiality low, integrity low, availability none.
