CVE-2024-41629
📋 TL;DR
Texas Instruments Fusion Digital Power Designer v7.10.1 stores credentials in plaintext, allowing local attackers to read sensitive authentication information. This affects users of this specific version of the power management software. Attackers need local access to the system where the software is installed.
💻 Affected Systems
- Texas Instruments Fusion Digital Power Designer
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers obtain administrative credentials for power management systems, potentially gaining control over power infrastructure or using credentials for lateral movement.
Likely Case
Local users or malware with file system access can extract credentials stored in plaintext configuration files.
If Mitigated
With proper access controls and monitoring, credential theft can be detected and contained before misuse.
🎯 Exploit Status
Exploitation involves reading plaintext files, which is trivial for any user with file system access. The vulnerability disclosure includes technical details.
