The product constructs pathnames from user input, but it does not handle or incorrectly handles a pathname containing a Windows device name such as AUX or CON. This typically leads to denial of service or an information exposure when the application attempts to process the pathname as a regular file.
Not properly handling virtual filenames (e.g. AUX, CON, PRN, COM1, LPT1) can result in different types of vulnerabilities. In some cases an attacker can request a device via injection of a virtual filename in a URL, which may cause an error that leads to a denial of service or an error page that reveals sensitive information. A product that allows device names to bypass filtering runs the risk of an attacker injecting malicious code in a file with the name of a device.
Be familiar with the device names in the operating system where your system is deployed. Check input for these device names.
CVE-2002-0106Server allows remote attackers to cause a denial of service via a series of requests to .JSP files that contain an MS-DOS device name.
CVE-2002-0200Server allows remote attackers to cause a denial of service via an HTTP request for an MS-DOS device name.
CVE-2002-1052Product allows remote attackers to use MS-DOS device names in HTTP requests to cause a denial of service or obtain the physical path of the server.
CVE-2001-0493Server allows remote attackers to cause a denial of service via a URL that contains an MS-DOS device name.
CVE-2001-0558Server allows a remote attacker to create a denial of service via a URL request which includes a MS-DOS device name.
