Description

The Spring Integration ZIP extension, prior to 1.0.2, exposes an arbitrary file write vulnerability. The vulnerability 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. When the filename gets concatenated to the target extraction directory, the final path ends up outside the target folder. The previous CVE-2018-1261 prevented the framework itself from writing the file. While the framework itself now does not write such files, it does present the errant path to the user application, which could inadvertently write the file using that path.

Preconditions include using the unzip transformer and unpacking zip files from untrusted sources.

Affected Spring Products and Versions

Spring Integration Zip Community Extension:

• 1.0.0.RELEASE - 1.0.1.RELEASE

Mitigation

Users of affected versions should upgrade to the corresponding fixed version.

If you are not able to upgrade, make sure you do not unzip untrusted zip files.
