📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An attacker with local administrative access could extract plaintext passwords, potentially gaining access to other systems or escalating privileges across the infrastructure.
Likely Case
A malicious insider or compromised administrator account could harvest credentials stored in plaintext, leading to lateral movement within the environment.
If Mitigated
With proper access controls and monitoring, the impact is limited to credential exposure without immediate system takeover.
