Summary
IBM Maximo Application Suite 9.1, 9.0, 8.11, and 8.10 does not set the secure attribute on authorization tokens or session cookies. An attacker may obtain cookie values by sending a user an http:// link or planting it on a visited site; the cookie is sent over the insecure link and can be captured by snooping traffic.
Risk Assessment
Interception of session cookies or authorization tokens may allow session hijacking and unauthorized access to the application. The risk is especially relevant on networks where traffic can be eavesdropped.
Recommendation
Upgrade IBM Maximo Application Suite to a version containing the fix. Enforce HTTPS where possible and consider additional session cookie protections.
