How to Check if You Are Affected

To determine whether your application is affected by CVE-2023-38708, 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 10.6.7), 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 A path traversal vulnerability exists in the `AssetController::importServerFilesAction`, which allows an attacker to overwrite or modify sensitive files by manipulating the pimcore_log parameter.This can lead to potential denial of service---key file overwrite. The impact of this vulnerability allows attackers to: Overwrite or modify sensitive files, potentially leading to unauthorized access, privilege escalation, or disclosure of confidential information. Tamper with system settings by modifying key files, such as the hosts file in Windows or configuration files for other services. Cause a denial of service (DoS) if critical system files are overwritten or deleted. The consequences of exploiting this vulnerability can be detrimental to the confidentiality, integrity, and availability of the affected system. It's crucial to address this vulnerability to protect sensitive data and ensure the proper functioning of the system. ### Patches Update to version 10.6.7 or apply this patch manually https://github.com/pimcore/pimcore/commit/58012d0e3b8b926fb54eccbd64ec5c993b30c22c.patch ### Workarounds Apply patch https://github.com/pimcore/pimcore/commit/58012d0e3b8b926fb54eccbd64ec5c993b30c22c.patch manually.
