How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-24977, inspect your project dependencies for Impresscms/impresscms:

inspect dependencies for impresscms/impresscms

Analyze the terminal output to locate any version of Impresscms/impresscms in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.4.2), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In Impresscms/impresscms, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

ImpressCMS before 1.4.2 allows unauthenticated remote code execution via ...../// directory traversal in origName or imageName, leading to unsafe interaction with the CKEditor processImage.php script. The payload may be placed in PHP_SESSION_UPLOAD_PROGRESS when the PHP installation supports upload_progress.
