Security Bulletin

This security bulletin contains one high risk vulnerability.

1) Path traversal

EUVDB-ID: #VU15972

Risk: High

CVSSv4.0: 6.1 [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]

CVE-ID: CVE-2018-8009

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

Exploit availability: No

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".

Mitigation

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

Vulnerable software versions

Hadoop: 2.2 - 3.1.0
