In OpenMNS Horizon 31.0.8 and versions earlier than 32.0.2 and related Meridian versions, any user that has the ROLE_FILESYSTEM_EDITOR can easily escalate their privileges to ROLE_ADMIN or any other role. Jenkins Folders Plugin 6.846.v23698686f0f6 and earlier displays an error message that includes an absolute path of a log file when attempting to access the Scan Organization Folder Log if no logs are available, exposing information about the Jenkins controller file system. Use a version of Python 3 that is not affected, downgrade to Python 3.10 series temporarily, or wait until Python 3.11.5 is released and upgrade to the latest version of Python 3.11 series.
Fixes will be available in:Python 3.12.0rc2 and 3.11.5. Secondly, Python 3.11, and 3.12 has fixed the underlying issue in `os.path.normpath` to no longer truncate on the first `0x00` found, returning the behavior to pre-3.11 Python, un an as of yet unreleased version. While valid in directory/file names, we would strongly consider it a mistake to use null-bytes in naming files/directories. Pyramid version 2.0.2 rejects any path that contains a null-byte out of caution. No further path traversal exists, and the only file that could be disclosed accidentally is `index.html`. A path traversal vulnerability in Pyramid versions 2.0.0 and 2.0.1 impacts users of Python 3.11 that are using a Pyramid static view with a full filesystem path and have a `index.html` file that is located exactly one directory above the location of the static view's file system path. Pyramid is an open source Python web framework. OpenNMS thanks Erik Wynter for reporting this issue. Meridian and Horizon installation instructions state that they are intended for installation within an organization's private networks and should not be directly accessible from the Internet. The solution is to upgrade to Meridian 2023.1.5 or Horizon 32.0.2 or newer. In OpenMNS Horizon 31.0.8 and versions earlier than 32.0.2, the file editor which is accessible to any user with ROLE_FILESYSTEM_EDITOR privileges is vulnerable to XXE injection attacks.
