CVE-2024-7577
📋 TL;DR
IBM InfoSphere Information Server 11.7 may expose sensitive user credentials in log files during new installations. This vulnerability allows attackers with access to installation logs to obtain authentication credentials. Only new installations of version 11.7 are affected.
💻 Affected Systems
- IBM InfoSphere Information Server
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers obtain administrative credentials and gain full control over the InfoSphere Information Server instance, potentially accessing sensitive data and systems.
Likely Case
Local users or attackers with file system access discover credentials in installation logs and use them for unauthorized access to the application.
If Mitigated
With proper log access controls and credential rotation, impact is limited to potential credential exposure without successful exploitation.
🎯 Exploit Status
Exploitation requires access to installation log files, which typically requires some level of system access.
