Description Pedro Sampaio 2019-04-04 02:28:01 UTC

Apache Karaf kar deployer reads .kar archives and extracts the paths from the "repository/" and "resources/" entries in the zip file. It then writes out the content of these paths to the Karaf repo and resources directories. However, it doesn't do any validation on the paths in the zip file. This means that a malicious user could craft a .kar file with ".." directory names and break out of the directories to write arbitrary content to the filesystem. This is the "Zip-slip" vulnerability - https://snyk.io/research/zip-slip-vulnerability. This vulnerability is low if the Karaf process user has limited permission on the filesystem. Any Apache Karaf releases prior 4.2.3 is impacted.

Comment 3 Summer Long 2019-04-09 23:55:03 UTC

Statement:

All versions of Red Hat OpenStack Platform's OpenDaylight contain the vulnerable code. However, the vulnerability is not exploitable given the way the library is used within OpenDaylight, and therefore no packages will be updated. OpenDaylight was technical preview prior to OpenStack 13 and deprecated in OpenStack 14.
