NixOS vulnerability analysis and mitigation

Overview

In NCH Quorum v2.03 and earlier, a Cross-Site Scripting (XSS) vulnerability exists via /conference?id= parameter (reflected). The vulnerability was discovered and disclosed on July 25, 2021, affecting NCH Software's Quorum conference server software (NVD, CISA).

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 CVSS v2.0 Base Score is 3.5 (LOW) with vector (AV:N/AC:M/Au:S/C:N/I:P/A:N). The vulnerability is categorized under CWE-79: Improper Neutralization of Input During Web Page Generation (NVD).

Impact

The vulnerability allows authenticated users to inject JavaScript Cross-Site Scripting payloads into fields in Quorum to create stored or reflected XSS conditions. While some basic script tags are filtered, this protection can be bypassed with more diverse payloads (GitHub POC).

Mitigation and workarounds

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