SWServer hexadecimal URL encoded directory traversal
|swserver-encoded-directory-traversal (9981)||Medium Risk|
SWServer could allow a remote attacker to traverse directories on the Web server. A remote attacker could send a specially-crafted URL request containing hexadecimal URL encoded "dot dot" sequences (in the form of %2f%2e%2e%2f or %5c%2e%2e%5c) to traverse directories and view files and folders outside of the Web root directory.
Upgrade to the latest version of SWServer (2.3 or later), available from the SWServer Web page. See References.
