CVE-2022-34323 — Sage Sage Xrt Business Exchange security vulnerability

Medium CVSS 5.4

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.)

Cross-site scripting and unsafe browser output

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace reflected, stored, and DOM-derived untrusted values into HTML, attributes, URLs, styles, scripts, and client-side template sinks.
  • Identify affected origins, authenticated user roles, sensitive browser capabilities, and where content is shared across tenants.
  • Review framework escaping, rich-text sanitization, legacy templates, and client-side rendering paths.

Remediate safely

  • Use context-aware framework output encoding and safe DOM APIs; keep untrusted data out of executable contexts.
  • Sanitize intentionally supported markup with a maintained allowlist policy and validate URLs and attributes separately.
  • Update affected rendering components and add tests for every output context using inert sentinel markup.
