CVE-2022-36007 Information

Description

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: [ \/Users/foo/resources\ ] When passing relative paths to these two vulnerable functions everything is fine: (load-resource est.png\) => loads the file /Users/foo/resources/test.png\ (load-resource \../resources-alt/test.png\) => 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 \/Users/foo/resources/test.png\) => loads the file /Users/foo/resources/test.png\ (load-resource \/Users/foo/resources-alt/test.png\) => 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 \/Users/foo/resources\ the actor can cause loading a resource also from \/Users/foo/resources-alt\ but not from \/Users/foo/images\. 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.
