Accellion · Accellion Ftp Server · CVE-2016-9500
**Name of the Vulnerable Software and Affected Versions**
Accellion FTP server versions prior to FTA 9 12 220
**Description**
The issue concerns the use of the Accusoft Prizm Content flash component in the Accellion FTP server, which contains multiple parameters, such as `customTabCategoryName` and `customButton1Image`, that are vulnerable to cross-site scripting.
**Recommendations**
For Accellion FTP server versions prior to FTA 9 12 220, update to version FTA 9 12 220 or later to resolve the issue. As a temporary workaround, consider restricting access to the parameters `customTabCategoryName` and `customButton1Image` to minimize the risk of exploitation.
