CVE-2019-0214: Apache Archiva arbitrary file write and delete on the server
Severity: Medium
Vendor:
The Apache Software Foundation
Versions Affected:
Apache Archiva 2.0.0 - 2.2.3
The unsupported versions 1.x are also affected.
It is possible to write files to the archiva server at arbitrary locations by
using the artifact upload mechanism.
Existing files can be overwritten, if the archiva run user has appropriate
permission on the filesystem for the target file.
Mitigation:
It is highly recommended to upgrade to Archiva 2.2.4 or higher, where
additional validations are implemented to prevent such malicious parameter
values.
As intermediate action you may reduce the number of users that are allowed to
upload to archiva and make sure, that the archiva run user may have only
write permission to the directories needed.
