AI Powered Q&A
Can you explain this vulnerability to me?
The FuseDesk plugin for WordPress, up to and including version 6.8, is vulnerable to Stored Cross-Site Scripting (XSS) through its fusedesk_newcase shortcode. This vulnerability arises because the plugin does not properly sanitize or escape the input provided in the 'emailtext' attribute. As a result, authenticated users with Contributor-level access or higher can inject malicious web scripts into pages. These scripts will execute whenever any user accesses the affected page, potentially compromising user security.
How can this vulnerability impact me? :
This vulnerability allows attackers with Contributor-level access or above to inject arbitrary scripts into web pages via the FuseDesk plugin's fusedesk_newcase shortcode. The injected scripts execute in the context of users visiting those pages, which can lead to several impacts including theft of user credentials, session hijacking, unauthorized actions performed on behalf of users, and potential spread of malware. Since the attack is stored, the malicious code persists and affects all users who view the compromised content.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
I don't know
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability involves Stored Cross-Site Scripting (XSS) via the FuseDesk plugin's fusedesk_newcase shortcode, specifically through the 'emailtext' attribute. Detection would involve identifying injected scripts in pages that use this shortcode.
Since the vulnerability requires authenticated users with Contributor-level access or higher to inject scripts, detection can focus on monitoring pages where the fusedesk_newcase shortcode is used and inspecting the 'emailtext' attribute for suspicious or unexpected script content.
No specific detection commands or automated detection tools are provided in the available resources.
What immediate steps should I take to mitigate this vulnerability?
To mitigate this vulnerability, the immediate step is to update the FuseDesk plugin to a version later than 6.8 where the input sanitization and output escaping issues on the 'emailtext' attribute have been fixed.
If an update is not immediately available, restrict Contributor-level and higher users from accessing or using the fusedesk_newcase shortcode functionality until a patch or update is applied.
Additionally, review and sanitize any user input related to the 'emailtext' attribute manually or via custom code to prevent script injection.
