CVE-2021-37464: 
NixOS vulnerability analysis and mitigation

Overview

CVE-2021-37464 affects NCH Quorum version 2.03 and earlier, where a Cross-Site Scripting (XSS) vulnerability exists via the Conference Description feature. This stored XSS vulnerability was discovered and disclosed in July 2021, impacting the web interface of the NCH Quorum telephone conference server software (NCH Product, NVD).

Technical details

The vulnerability is classified as a Cross-Site Scripting (XSS) issue with a CVSS v3.1 base score of 5.4 (Medium) and vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N. The vulnerability stems from insufficient input validation in the Conference Description field, allowing authenticated users to inject malicious JavaScript code that gets stored and executed when other users view the affected content (NVD, GitHub POC).

Impact

When successfully exploited, this vulnerability allows attackers to inject and execute arbitrary web scripts or HTML in the context of other users' browsers. Since this is a stored XSS vulnerability, the malicious code persists in the application and executes whenever users access the affected Conference Description content (GitHub POC).

Mitigation and workarounds

Users should upgrade to a version newer than Quorum 2.03. NCH Software has marked this as a legacy program that they no longer support (NCH Product).
