CWE-22

Wikmd is a file based wiki that uses markdown. Prior to version 1.7.1, Wikmd is vulnerable to path traversal when accessing `/list/` and discloses lists of files located on the server including sensitive data. Version 1.7.1 fixes this issue.

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 “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 v1.10.17 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.

Streamlit is a data oriented application development framework for python. Users hosting Streamlit app(s) that use custom components are vulnerable to a directory traversal attack that could leak data from their web server file-system such as: server logs, world readable files, and potentially other sensitive information. An attacker can craft a malicious URL with file paths and the streamlit server would process that URL and return the contents of that file. This issue has been resolved in version 1.11.1. Users are advised to upgrade. There are no known workarounds for this issue.

MinIO is a High Performance Object Storage released under GNU Affero General Public License v3.0. In affected versions all ‘admin’ users authorized for `admin:ServerUpdate` can selectively trigger an error that in response, returns the content of the path requested. Any normal OS system would allow access to contents at any arbitrary paths that are readable by MinIO process. Users are advised to upgrade. Users unable to upgrade may disable ServerUpdate API by denying the `admin:ServerUpdate` action for your admin users via IAM policies.

Sanic is an opensource python web server/framework. Affected versions of sanic allow access to lateral directories when using `app.static` if using encoded `%2F` URLs. Parent directory traversal is not impacted. Users are advised to upgrade. There is no known workaround for this issue.

pyenv 1.2.24 through 2.3.2 allows local users to gain privileges via a .python-version file in the current working directory. An attacker can craft a Python version string in .python-version to execute shims under their control. (Shims are executables that pass a command along to a specific version of pyenv. The version string is used to construct the path to the command, and there is no validation of whether the version specified is a valid version. Thus, relative path traversal can occur.)
