IBM Engineering Lifecycle Optimization - Engineering Insights 7.0.2 and 7.0.3 uses a web link with untrusted references to an external site. A remote attacker could exploit this vulnerability to expose sensitive information or perform unauthorized actions on the victims’ web browser.

Weakness

The web application produces links to untrusted external sites outside of its sphere of control, but it does not properly prevent the external site from modifying security-critical properties of the window.opener object, such as the location property.

Affected Software

Name Vendor Start Version End Version
Engineering_lifecycle_optimization_-_engineering_insights Ibm 7.0.2 (including) 7.0.2 (including)
Engineering_lifecycle_optimization_-_engineering_insights Ibm 7.0.3 (including) 7.0.3 (including)

Potential Mitigations

  • When creating a link to an external document using the tag with a defined target, for example “_blank” or a named frame, provide the rel attribute with a value “noopener noreferrer”.
  • If opening the external document in a new window via javascript, then reset the opener by setting it equal to null.
  • Do not use “_blank” targets. However, this can affect the usability of the application.
