How to Fix CVE-2023-39528

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

prestashop/prestashop fixed: 8.1.1 
Upgrade prestashop/prestashop to 8.1.1
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 prestashop/prestashop

How to Check if You Are Affected

To determine whether your application is affected by CVE-2023-39528, inspect your project dependencies for Prestashop/prestashop:

inspect dependencies for prestashop/prestashop

Analyze the terminal output to locate any version of Prestashop/prestashop in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 8.1.1), 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 Prestashop/prestashop, 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 `displayAjaxEmailHTML` method can be used to read any file on the server, potentially even outside of the project if the server is not correctly configured. This vulnerability can be exacerbated when coupled with [CWE-502](https://cwe.mitre.org/data/definitions/502.html), which pertains to the Deserialization of Untrusted Data. Such a combination could potentially lead to a Remote Code Execution (RCE) vulnerability ### Patches 8.1.1 ### Found by Aleksey Solovev (Positive Technologies) ### Workarounds ### References
