How to Fix CVE-2022-48366

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

ezsystems/ezplatform-kernel fixed: 1.3.19 
Upgrade ezsystems/ezplatform-kernel to 1.3.19
ezsystems/ezpublish-kernel fixed: 7.5.29 
Upgrade ezsystems/ezpublish-kernel to 7.5.29
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 ezsystems/ezplatform-kernel

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-48366, inspect your project dependencies for Ezsystems/ezplatform kernel:

inspect dependencies for ezsystems/ezplatform-kernel

Analyze the terminal output to locate any version of Ezsystems/ezplatform kernel in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.3.19), 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-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition'), where the product contains a concurrent code sequence that requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence operating concurrently. In Ezsystems/ezplatform kernel, 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

Ibexa DXP is using random execution time to hinder timing attacks against user accounts, a method of discovering whether a given account exists in a system without knowing its password, thus affecting privacy. This implementation was found to not be good enough in some situations. The fix replaces this with constant time functionality, configured in the new security.yml parameter 'ibexa.security.authentication.constant_auth_time'. It will log a warning if the constant time is exceeded. If this happens the setting should be increased.
