Description
Impact
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 "test.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 v1.10.16 are affected by this issue.
Patches
Upgrade to Venice >= 1.10.17, if you are on a version < 1.10.17
Workarounds
If you cannot upgrade the library, you can control the functions that can be used in Venice with a sandbox. If it is appropriate, the functions `load-file` and `load-resource` can be blacklisted in the sandbox.
