CVE-2023-26288
📋 TL;DR
IBM Aspera Orchestrator 4.0.1 fails to invalidate user sessions after password changes, allowing authenticated users to maintain access with old credentials and potentially impersonate other users. This affects organizations using IBM Aspera Orchestrator 4.0.1 for high-speed data transfer management.
💻 Affected Systems
- IBM Aspera Orchestrator
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An authenticated malicious insider could maintain persistent access to another user's account after password change, leading to data theft, unauthorized file transfers, or privilege escalation within the Aspera ecosystem.
Likely Case
Session persistence after legitimate password changes creates confusion and potential access control issues, with accidental or opportunistic misuse more probable than targeted attacks.
If Mitigated
With proper session management controls, the impact is limited to temporary access anomalies that are quickly detected and resolved.
🎯 Exploit Status
Exploitation requires authenticated access and knowledge of session management flaws; no public exploits have been documented.
