Vulnerability from fkie_nvd - Published: 2019-08-30 09:15 - Updated: 2026-06-17 01:47

Severity

6.1 (Medium) - CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N

Summary

The ASG/ProxySG FTP proxy WebFTP mode allows intercepting FTP connections where a user accesses an FTP server via a ftp:// URL in a web browser. A stored cross-site scripting (XSS) vulnerability in the WebFTP mode allows a remote attacker to inject malicious JavaScript code in ASG/ProxySG's web listing of a remote FTP server. Exploiting the vulnerability requires the attacker to be able to upload crafted files to the remote FTP server. Affected versions: ASG 6.6 and 6.7 prior to 6.7.4.2; ProxySG 6.5 prior to 6.5.10.15, 6.6, and 6.7 prior to 6.7.4.2.
