CVE-2022-36007

Summary

Venice is a Clojure inspired sandboxed Lisp dialect with excellent Java interoperability. A partial path traversal issue exists within the functions load-file and load-resource. These functions can be limited to load files from a list of load paths. Assuming Venice has been configured with the load paths: [ &#34;/Users/foo/resources&#34; ] When passing relative paths to these two vulnerable functions everything is fine: (load-resource &#34;test.png&#34;) => loads the file "/Users/foo/resources/test.png" (load-resource &#34;../resources-alt/test.png&#34;) => rejected, outside the load path When passing absolute paths to these two vulnerable functions Venice may return files outside the configured load paths: (load-resource &#34;/Users/foo/resources/test.png&#34;) => loads the file "/Users/foo/resources/test.png" (load-resource &#34;/Users/foo/resources-alt/test.png&#34;) => loads the file "/Users/foo/resources-alt/test.png" !!! The latter call suffers from the Partial Path Traversal vulnerability. This issue’s scope is limited to absolute paths whose name prefix matches a load path. E.g. for a load-path &#34;/Users/foo/resources&#34;, the actor can cause loading a resource also from &#34;/Users/foo/resources-alt&#34;, but not from &#34;/Users/foo/images&#34;. Versions of Venice before and including v1.10.17 are affected by this issue. Upgrade to Venice >= 1.10.18, if you are on a version < 1.10.18. There are currently no known workarounds.
