Serv-U File Renaming Directory Traversal and 'STOU' DoS Vulnerabilities
Published: 2008-10-14 14:57:31
CVSS Base Vector:
AV:N/AC:L/Au:N/C:P/I:P/A:P
Detection Type:
Windows Registry
Summary:
The host is running Serv-U FTP Server, which is prone to Directory
Traversal and Denial of Service Vulnerabilities.
Technical Details:
The flaws are due to,
- error in handling 'STOU' FTP command. It can exhaust available CPU
resources when exploited through a specially crafted argument value.
- input validation error in the FTP service when renaming files which can be
exploited to overwrite or rename files via directory traversal attacks.
Affected Versions:
RhinoSoft Serv-U FTP Server 7.3.0.0 and prior
Solution Type:
Vendor Patch
Recommendations:
Upgrade to RhinoSoft Serv-U FTP Server 10 or later.
Impact:
Successful exploitation allows an attacker to write arbitrary files to
locations outside of the application's current directory, and deny the service.

What's vulnerability management?
Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
