CVSS v3.1

Official Description

Multiple XSS issues were discovered in Sage XRT Business Exchange 12.4.302 that allow an attacker to execute JavaScript code in the context of other users' browsers. The attacker needs to be authenticated to reach the vulnerable features. An issue is present in the Filters and Display model features (OnlineBanking > Web Monitoring > Settings > Filters / Display models). The name of a filter or a display model is interpreted as HTML and can thus embed JavaScript code, which is executed when displayed. This is a stored XSS. Another issue is present in the Notification feature (OnlineBanking > Configuration > Notifications and alerts > Alerts *). The name of an alert is interpreted as HTML, and can thus embed JavaScript code, which is executed when displayed. This is a stored XSS. (Also, an issue is present in the File download feature, accessible via /OnlineBanking/cgi/isapi.dll/DOWNLOADFRS. When requesting to show the list of downloadable files, the contents of three form fields are embedded in the JavaScript code without prior sanitization. This is essentially a self-XSS.)

Technical Analysis

CVE-2022-34323 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.

From a weakness classification perspective (CWE-79): Cross-site scripting (XSS) vulnerabilities allow attackers to inject malicious scripts into web pages viewed by other users.
