SurgeFTP error message cross-site scripting
| surgeftp-error-xss (35378) |  Medium Risk |
Description:
SurgeFTP is vulnerable to cross-site scripting, caused by improper validation of user-supplied input by the mirror server Web interface. A remote attacker could exploit this vulnerability using an invalid server response to inject malicious script into an error message which would be executed in a victim's Web browser within the security context of the hosting Web site, once the message is viewed. An attacker could use this vulnerability to steal the victim's cookie-based authentication credentials.
Platforms Affected:
- NetWin, SurgeFTP Server 2.3a1
Remedy:
Upgrade to the latest version of SurgeFTP (7/12/2007 or later), available from the SurgeFTP Web site. See References.
Consequences:
