- Affected
- Maven org.apache.knox:gateway-service-knoxsso < 1.6.1
- Fixed in
- 1.6.1· Vendor fix available
- Issue
- When using Apache Knox SSO prior to 1.6.1, a request could be crafted to redirect a user to a malicious page due to improper URL parsing. A request that included a specially crafted request parameter could be used to redirect the user to a page controlled by an attacker. This URL would need to be presented to the user outside the normal request flow through a XSS or phishing campaign.
Recommended action: Upgrade to 1.6.1 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
