Description

This security bulletin contains information about 1 vulnerability.


1) Path traversal (CVE-ID: CVE-2018-8009)

CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


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".
