Technical details
The vulnerability is a cleartext storage of sensitive information weakness in memory within Simplex Incident Manager / Autocall Fire Administrator versions before 2.01.05. The affected component stores sensitive data (credentials, API keys, or other secrets) unencrypted in process memory, allowing an attacker with local system access to read this information via memory inspection or dumps. The attack requires local access to the system; remote exploitation is not possible. An attacker could retrieve embedded sensitive data and use it to compromise the fire management system or related infrastructure. Patches are available in version 2.01.05 and later.
