Description

This security bulletin contains information about 1 vulnerability.


1) Path traversal (CVE-ID: CVE-2018-1797)

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

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


The vulnerability allows a remote attacker to conduct directory traversal attack.

The vulnerability exists due to improper validation of user-supplied input on systems that have an Enterprise Bundle Archive (EBA) installed and with a path external to the EBA. A remote attacker can trick the victim into extracting a specially crafted ZIP archive containing 'dot dot slash' sequences that, when executed, will write arbitrary files on the target system.

Note: This vulnerability is known as "Zip-Slip".
