CVE-2024-41777
📋 TL;DR
IBM Cognos Controller versions 11.0.0 and 11.0.1 contain hard-coded credentials that could be used for authentication, communication, or data encryption. This vulnerability allows attackers who discover these credentials to potentially gain unauthorized access to the system or sensitive data. Organizations using these specific versions of IBM Cognos Controller are affected.
💻 Affected Systems
- IBM Cognos Controller
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers gain administrative access to the Cognos Controller system, potentially compromising all financial data, manipulating reports, and using the system as a foothold for further network attacks.
Likely Case
Unauthorized users access sensitive financial data, modify reports, or disrupt business processes by exploiting the hard-coded credentials.
If Mitigated
With proper network segmentation and access controls, impact is limited to the Cognos Controller application itself, though data within it remains at risk.
🎯 Exploit Status
Exploitation requires discovering the hard-coded credentials, which may involve reverse engineering or other analysis techniques.
