CVE-2018-1261: Unsafe Unzip with spring-integration-zip
Severity
Critical
Vendor
Spring by Pivotal
Description
spring-integration-zip , versions prior to 1.0.1, exposes an arbitrary file write vulnerability, that can be achieved using a specially crafted zip archive (affects other archives as well, bzip2, tar, xz, war, cpio, 7z), that holds path traversal filenames. So when the filename gets concatenated to the target extraction directory, the final path ends up outside of the target folder.
This specifically applies to the unzip transformer.
This can only happen if an application using this library accepts and unpacks zip files from untrusted sources.
Affected VMware Products and Versions
Severity is critical unless otherwise noted.
- Spring Integration Zip Community Extension Project version 1.0.0.RELEASE
Mitigation
Users of affected versions should apply the following mitigation:
- Upgrade to the 1.0.1.RELEASE
Or do not unzip untrusted zip files.
