ZKTeco ZKBioSecurity 3.0 Multiple Reflected XSS Vulnerabilities
Description

ZKTeco ZKBioSecurity 3.0 contains multiple reflected cross-site scripting vulnerabilities that allow attackers to execute arbitrary HTML and script code by injecting malicious payloads through unsanitized parameters in multiple scripts. Attackers can craft malicious URLs with XSS payloads in vulnerable parameters to execute scripts in a user's browser session within the context of the affected application.

Solution
Sanitize all user inputs to prevent script execution and mitigate XSS vulnerabilities.
  • Validate and sanitize all input parameters.
  • Implement output encoding for user-supplied data.
  • Update software to the latest secure version.
  • Avoid using user input directly in HTML or script contexts.
