Cross-site scripting (XSS) vulnerability in the mirrored server management interface in SurgeFTP 2.3a1 allows user-assisted, remote FTP servers to inject arbitrary web script or HTML via a malformed response without a status code, which is reflected to the user in the resulting error message. NOTE: this can be leveraged for root access via a sequence of steps involving web script that creates a new FTP user account.
CVSS Severity (version 2.0):
Impact Subscore: 4.9
Exploitability Subscore: 8.6
CVSS Version 2 Metrics:
Access Vector: Network exploitable; Victim must voluntarily interact with attack mechanism
Access Complexity: Medium
Authentication: Not required to exploit
Impact Type: Allows unauthorized modification; Allows disruption of service
