Microsoft Windows zipped file decompression incorrect target path

win-zip-incorrect-path (10252) The risk level is classified as HighHigh Risk

Description:

Microsoft Windows 98 with Plus! Pack, Windows Me, and Windows XP could allow a remote attacker to place malicious files in any folder on a victim's system, caused by a vulnerability in the Compressed Folders feature. When unzipping a compressed folder, the target folder destination is not checked. This could allow a remote attacker to create a specially-crafted zip file that when decompressed, would cause a malicious file to be placed into any known folder on the victim's system, such as the startup folder, which would cause the malicious file to be executed when the victim's computer is restarted. An attacker could exploit this vulnerability by hosting the malicious file on a Web site or sending it to the victim as an email attachment.
