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".
Remediation
The vulnerability has been fixed in the versions 3.1.1, 3.0.3, 2.8.5, and 2.7.7.
