CVE-2022-24733: 
PHP vulnerability analysis and mitigation

Sylius, an open source eCommerce platform, was found to be vulnerable to clickjacking attacks in versions prior to 1.9.10, 1.10.11, and 1.11.2. The vulnerability, identified as CVE-2022-24733, was disclosed on March 14, 2022. The security flaw allowed an attacker-controlled page to load the website within an iframe, enabling potential clickjacking attacks where the attacker's page could overlay the target application's interface with a malicious interface (GitHub Advisory).

The vulnerability is classified as CWE-1021 (Improper Restriction of Rendered UI Layers or Frames) and received a CVSS v3.1 Base Score of 6.1 (MEDIUM) with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N. The vulnerability stems from missing HTTP headers that would prevent the website from being loaded in an iframe, making it susceptible to clickjacking attacks (NVD).

When exploited, this vulnerability allows attackers to create a malicious overlay interface that could trick users into performing unintended actions on the legitimate website. The attack could potentially lead to unauthorized actions being performed with the user's privileges, as the legitimate interface would be hidden beneath the attacker's overlay (GitHub Advisory).

The vulnerability is exploitable remotely and requires no special privileges, though it does require user interaction. An attacker needs to create a malicious page that loads the target Sylius website within an iframe and convince users to interact with the crafted interface (NVD).

The vulnerability has been fixed in versions 1.9.10, 1.10.11, and 1.11.2. For users unable to update immediately, a workaround is available by adding an X-Frame-Options header set to 'sameorigin' for every response from the application. This can be implemented by adding a new subscriber in the app that sets the appropriate header (GitHub Advisory).
