How to Fix CVE-2021-43789

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: 1.7.8.2 
Upgrade prestashop/prestashop to 1.7.8.2
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 prestashop/prestashop

How to Check if You Are Affected

To determine whether your application is affected by CVE-2021-43789, 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 1.7.8.2), 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-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection'), where the product constructs all or part of an sql command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended sql command when it is sent to a downstream component. without sufficient removal or quoting of sql syntax in user-controllable inputs, the generated sql query can cause those inputs to be interpreted as sql instead of ordinary user data. 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.
