How to Fix CVE-2023-30855

To remediate this vulnerability, upgrade all affected Pimcore/pimcore dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

pimcore/pimcore fixed: 10.5.18
Upgrade pimcore/pimcore to 10.5.18
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

inspect dependencies for pimcore/pimcore

How to Check if You Are Affected

To determine whether your application is affected by CVE-2023-30855, inspect your project dependencies for Pimcore/pimcore:

inspect dependencies for pimcore/pimcore

Analyze the terminal output to locate any version of Pimcore/pimcore in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 10.5.18), 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 Pimcore/pimcore, 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

### Impact The impact of this path traversal and arbitrary extension is limited (creation of arbitrary files and appending data to existing files) but when combined with the SQL Injection, the exported data `RESTRICTED DIFFUSION 9 / 9` can be controlled and a webshell can be uploaded. Attackers can use that to execute arbitrary PHP code on the server with the permissions of the webserver. ### Patches Update to version 10.5.18 or apply this patch manually https://github.com/pimcore/pimcore/commit/7f788fa44bc18bc1c9182c25e26b770a1d30b62f.patch ### Workarounds Apply patch https://github.com/pimcore/pimcore/commit/7f788fa44bc18bc1c9182c25e26b770a1d30b62f.patch manually. ### References https://github.com/pimcore/pimcore/pull/14498
