How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-0666, inspect your project dependencies for Microweber/microweber:

inspect dependencies for microweber/microweber

Analyze the terminal output to locate any version of Microweber/microweber in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.2.11), 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-93: Improper Neutralization of CRLF Sequences ('CRLF Injection'), where the product uses crlf (carriage return line feeds) as a special element, e.g. to separate lines or records, but it does not neutralize or incorrectly neutralizes crlf sequences from inputs. In Microweber/microweber, 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

CRLF Injection leads to Stack Trace Exposure due to lack of filtering at https://demo.microweber.org/ in Packagist microweber/microweber prior to 1.2.11.
