How to Fix CVE-2020-29653

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

froxlor/froxlor fixed: Latest secure release 
Upgrade froxlor/froxlor to Latest secure release
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 froxlor/froxlor

How to Check if You Are Affected

To determine whether your application is affected by CVE-2020-29653, inspect your project dependencies for Froxlor/froxlor:

inspect dependencies for froxlor/froxlor

Analyze the terminal output to locate any version of Froxlor/froxlor in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), 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-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Froxlor/froxlor, 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

Froxlor through 0.10.22 does not perform validation on user input passed in the customermail GET parameter. The value of this parameter is reflected in the login webpage, allowing the injection of arbitrary HTML tags. Note: Froxlor version 0.10.22 introduces AntiXSS cross-site scripting protection, but AntiXSS only provides partial protection for this particular issue.
