qcubed/qcubed fixed: 3.2 
Upgrade qcubed/qcubed to 3.2
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 qcubed/qcubed

How to Check if You Are Affected

To determine whether your application is affected by CVE-2020-24914, inspect your project dependencies for Qcubed/qcubed:

inspect dependencies for qcubed/qcubed

Analyze the terminal output to locate any version of Qcubed/qcubed in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.2), 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-915: Improperly Controlled Modification of Dynamically-Determined Object Attributes, where the product receives input from an upstream component that specifies multiple attributes, properties, or fields that are to be initialized or updated in an object, but it does not properly control which attributes can be modified. In Qcubed/qcubed, 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

A PHP object injection bug in profile.php in qcubed (all versions including 3.1.1) unserializes the untrusted data of the POST-variable "strProfileData" and allows an unauthenticated attacker to execute code via a crafted POST request.
