CVE-2014-125098: Dart http_server Directory Listing virtual_directory.dart VirtualDirectory cross site scripting

A vulnerability was found in Dart http_server up to 0.9.5 and classified as problematic. Affected by this issue is the function VirtualDirectory of the file lib/src/virtual_directory.dart of the component Directory Listing Handler. The manipulation of the argument request.uri.path leads to cross site scripting. The attack may be launched remotely. Upgrading to version 0.9.6 is able to address this issue. The name of the patch is 27c1cbd8125bb0369e675eb72e48218496e48ffb. It is recommended to upgrade the affected component. The identifier of this vulnerability is VDB-225356.

Security readout for executives and security teams

Plain-English summary

This is a cross-site scripting flaw in Dart http_server directory listings. A malicious path could cause script content to run in a user's browser when viewing a vulnerable listing. Business impact is mainly session, trust, and content integrity risk, not direct server takeover based on the cited CVSS vector.

Executive priority

Prioritize remediation for any exposed or user-accessible directory listing. This is not rated critical, but it is easy to reach remotely and can affect users' browsers. Legacy or internet-facing deployments should be fixed in the next normal security maintenance window.

Technical view

CVE-2014-125098 affects Dart http_server 0.9.0 through 0.9.5. The VirtualDirectory handler in lib/src/virtual_directory.dart mishandles request.uri.path in directory listing output, causing CWE-79 XSS. The issue is remotely reachable, unauthenticated, low complexity, and fixed in version 0.9.6 by commit 27c1cbd8125bb0369e675eb72e48218496e48ffb.

Likely exposure

Exposure is likely limited to applications still using Dart http_server 0.9.0-0.9.5 with VirtualDirectory directory listings reachable by users. Internet-facing file browsers, developer tools, internal dashboards, or legacy Dart services are the main places to check.

Exploitation context

The source bundle says remote attack is possible, but KEV is false and no cited source states active exploitation. Treat it as a credible browser-side risk where vulnerable directory listings are exposed, especially if authenticated users or administrators browse them.

Researcher notes

Evidence supports affected versions, vulnerable function, CWE-79 classification, CVSS v2 5.0, and fixed release 0.9.6. The bundle does not provide proof-of-concept details, active exploitation evidence, or broader affected products beyond Dart http_server.

Mitigation direction

  • Upgrade Dart http_server to version 0.9.6 or later.
  • If upgrade is delayed, disable public VirtualDirectory directory listings.
  • Restrict vulnerable directory listings to trusted networks or authenticated users.
  • Review vendor release and patch notes before deploying compensating controls.
  • Retire legacy services that depend on unsupported or archived components.

Validation and detection

  • Inventory Dart services and dependency lockfiles for http_server versions 0.9.0 through 0.9.5.
  • Confirm whether VirtualDirectory directory listings are enabled and reachable.
  • Verify deployed artifacts use http_server 0.9.6 or a fixed replacement.
  • Review exposed routes for directory listing pages served to browsers.
  • Check application logs for unusual encoded or script-like path requests.
