What is CVE-2022-50787?

The SOUND4 IMPACT, FIRST, PULSE, and Eco applications, specifically versions 2.x, are susceptible to an unauthenticated stored cross-site scripting vulnerability. This security flaw arises when the username parameter processes unvalidated input, permitting attackers to inject malicious scripts. Once exploited, these scripts can execute harmful HTML and JavaScript code in the browser sessions of any user accessing the compromised application, leading to potential data exposure and session hijacking.

BigVoice2 1.30

BigVoice4 1.2

Impact/Pulse Eco 1.16
