## Affected

- IBM WebSphere Application Server: 7.0, 8.0, 8.5, 9.0

## Description

IBM WebSphere Application Server 7.0, 8.0, 8.5, and 9.0 using Enterprise bundle Archives (EBA) could allow a local attacker to traverse directories on the system. By persuading a victim to extract a specially-crafted ZIP archive containing "dot dot slash" sequences (../), an attacker could exploit this vulnerability to write to arbitrary files on the system. Note: This vulnerability is known as "Zip-Slip". IBM X-Force ID: 149427.
