AI Powered Q&A
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
The vulnerability allows authenticated administrators to inject arbitrary web scripts via stored cross-site scripting, potentially leading to unauthorized access or manipulation of data.
Such unauthorized access or data manipulation could impact compliance with standards like GDPR and HIPAA, which require protection of personal and sensitive information against unauthorized access and integrity breaches.
However, the provided information does not explicitly describe the direct impact on compliance with these regulations.
Can you explain this vulnerability to me?
The Call for Price plugin for WooCommerce on WordPress has a Stored Cross-Site Scripting (XSS) vulnerability in all versions up to and including 4.2.0. This vulnerability arises because the plugin does not properly sanitize input or escape output in its admin settings.
Authenticated users with administrator-level permissions or higher can exploit this flaw to inject malicious web scripts into pages. These scripts will execute whenever any user accesses the affected page.
This vulnerability specifically affects multi-site WordPress installations and installations where the unfiltered_html capability has been disabled.
How can this vulnerability impact me? :
This vulnerability can allow attackers with admin-level access to inject malicious scripts that execute in the context of other users visiting the affected pages.
Such script execution can lead to theft of user credentials, session hijacking, defacement, or other malicious actions depending on the injected script.
Because the vulnerability requires administrator-level permissions, it primarily impacts environments where such users are compromised or malicious.
What immediate steps should I take to mitigate this vulnerability?
To mitigate this vulnerability, you should update the Call for Price for WooCommerce plugin to a version later than 4.2.0 where the issue is fixed.
Additionally, ensure that your WordPress installation is not a multi-site setup or that the unfiltered_html setting is enabled, as the vulnerability only affects multi-site installations or those with unfiltered_html disabled.
Limit administrator-level permissions to trusted users only, since exploitation requires authenticated users with such permissions.
