How to Fix CVE-2021-43852

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

oro/platform fixed: 4.1.14 
Upgrade oro/platform to 4.1.14
oro/platform fixed: 4.2.8 
Upgrade oro/platform to 4.2.8
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 oro/platform

How to Check if You Are Affected

To determine whether your application is affected by CVE-2021-43852, inspect your project dependencies for Oro/platform:

inspect dependencies for oro/platform

Analyze the terminal output to locate any version of Oro/platform in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.1.14), 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-1321: Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution'), where the product receives input from an upstream component that specifies attributes that are to be initialized or updated in an object, but it does not properly control modifications of attributes of the object prototype. In Oro/platform, 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

### Summary By sending a specially crafted request, an attacker could inject properties into existing JavaScript language construct prototypes, such as objects. Later this injection may lead to JS code execution by libraries that are vulnerable to Prototype Pollution. ### Workarounds Configure WAF to drop requests containing next strings: `__proto__` , `constructor[prototype]`, `constructor.prototype`
