Security readout for executives and security teams
Plain-English summary
CVE-2023-46948 is a reflected XSS issue in Temenos T24 Browser R19.40. A malicious link or request could cause JavaScript to run in a user's browser through the skin parameter. Business risk is mainly session, data-view, or transaction-context abuse if a targeted user interacts.
Executive priority
Treat this as a moderate-priority application security issue. It is not presented as actively exploited, but banking users and transaction workflows make targeted XSS meaningful when affected systems are exposed.
Technical view
The CVE describes CWE-79 reflected XSS in about.jsp and genrequest.jsp via the skin parameter. CVSS 3.1 is 5.4: network reachable, low complexity, low privileges, user interaction required, changed scope, low confidentiality and integrity impact, no availability impact.
Likely exposure
Exposure is most likely limited to organizations running Temenos T24 Browser R19.40 with reachable about.jsp or genrequest.jsp components. The structured affected-product metadata is incomplete, so confirm product version and deployment details internally.
Exploitation context
The bundle does not show CISA KEV listing or active exploitation evidence. A public GitHub reference exists, but the provided sources do not establish exploitation in the wild. User interaction is required according to the CVSS vector.
Researcher notes
Key gaps: no vendor advisory, patch version, or complete CPE data appears in the supplied bundle. The CVE description identifies Temenos T24 Browser R19.40, while the affected metadata is marked n/a.
Mitigation direction
- Check Temenos guidance for a fixed version or supported mitigation.
- Inventory T24 Browser deployments and confirm whether R19.40 is present.
- Restrict access to affected browser components where business operations allow.
- Review WAF or application controls for reflected XSS protection.
- Prioritize remediation for internet-facing or high-privilege user workflows.
Validation and detection
- Confirm whether about.jsp and genrequest.jsp exist in deployed T24 Browser instances.
- Verify deployed T24 Browser version against R19.40 exposure.
- Review access logs for unusual skin parameter requests.
- Perform authorized non-destructive XSS validation in a test environment.
- Document whether vendor guidance or a patched build is available.
