1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-63289 CVSS Score: 9.1

The vulnerability in the Sogexia Android App, specifically in the encryption_helper.dart file, involves hardcoded encryption keys. This issue is critical due to the potential for unauthorized access to encrypted data. The CVSS score of 9.1 indicates a high severity, reflecting the significant risk posed by this vulnerability.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Reverse Engineering: Attackers can decompile the Android APK to extract the hardcoded encryption keys.
• Static Analysis: Security researchers or malicious actors can perform static code analysis to identify the hardcoded keys.
• Man-in-the-Middle (MitM) Attacks: If the keys are used for network communications, attackers can intercept and decrypt the data.

Exploitation Methods:

• Data Exfiltration: Once the keys are extracted, attackers can decrypt sensitive data stored on the device or transmitted over the network.
• Unauthorized Access: Attackers can use the keys to gain unauthorized access to encrypted resources, leading to data breaches.

3. Affected Systems and Software Versions

Affected Software:

• Sogexia Android App
• SDK versions: v35 and Max SDK 32

Fixed Version:

• SDK v36

Users running the affected SDK versions are at risk and should update to SDK v36 to mitigate the vulnerability.
