Multiple stored cross-site scripting (XSS) vulnerabilities in Train Scheduler App v1.0 allow attackers to execute arbitrary web scripts or HTML via a crafted payload injected into the Train Code, Train Name, and Destination text fields.

Security readout for executives and security teams

Plain-English summary

Train Scheduler App v1.0 can store unsafe text in train-related fields. When another user views those records, malicious script or HTML could run in their browser. This is a business risk for session exposure, account misuse, and content tampering, but the published severity is medium.

Executive priority

Treat as a moderate-priority web application issue. Prioritize if the app is internet-facing, used by multiple roles, or handles sensitive sessions. Do not assume active exploitation from the provided sources.

Technical view

CVE-2022-42992 is a stored cross-site scripting issue, CWE-79, in the Train Code, Train Name, and Destination text fields. CVSS 3.1 is 5.4 with network access, low complexity, low privileges required, user interaction required, changed scope, and low confidentiality and integrity impact.

Likely exposure

Likely exposure is limited to Train Scheduler App v1.0 deployments where authenticated users can create or edit train records and other users later view them. The source bundle lists vendor, product, CPEs, and affected versions as n/a beyond the description.

Exploitation context

The CVE is not listed as KEV in the source bundle, so active exploitation is not established here. A public GitHub proof-of-concept reference is cited, but this analysis does not use or reproduce exploit steps.

Researcher notes

Evidence is sparse: the CVE description names Train Scheduler App v1.0 and affected fields, while structured affected metadata is n/a. No official patch, vendor advisory, or active exploitation evidence is present in the provided bundle.

Mitigation direction

  • Check vendor or project guidance for an official fix or maintained replacement.
  • Restrict access to train record creation and editing to trusted users.
  • If maintaining the code, add input validation and output encoding for affected fields.
  • Review stored train records for unexpected HTML or script-like content.
  • Consider browser-side hardening such as a restrictive Content Security Policy.

Validation and detection

  • Inventory systems for Train Scheduler App v1.0 deployments.
  • Confirm who can modify Train Code, Train Name, and Destination fields.
  • Review code paths that render those fields for output encoding.
  • Inspect existing train records for unsafe HTML or script-like content.
  • Test remediation in a non-production environment using benign non-executing markers.
