Description

The vulnerability allows a remote attacker to conduct a directory traversal attack on the target system.

The vulnerability exists due to improper validation of files inside an archive file. A remote unauthenticated attacker can trick the victim into extracting a zip file that contains files that use directory traversal characters, cause a malicious file to be created outside the current working directory and cause a denial of service (DoS) condition or execute arbitrary code by overwriting other files on the system.

Successful exploitation of the vulnerability may result in system compromise.

Note: the vulnerability has been dubbed "Zip Slip".
