What the vulnerability does
01Description
The Viet contact plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 1.3.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
Explanation of Vulnerability in Simple Terms

The vulnerability requires high attack complexity and does not require user interaction. While the scope is changed, the confidentiality and integrity impacts are limited. Site administrators should update to a version newer than 1.3.2.
