Hardcoded Storage Credentials in Mobile App and Device Firmware (CVE-2025-10681)

CVE-2025-10681 exposes a critical vulnerability stemming from the presence of hardcoded storage credentials within a mobile application and its corresponding device firmware. These credentials, unfortunately, lack sufficient restrictions on end-user permissions and are not configured to expire after a reasonable period. The affected systems are not explicitly mentioned, but the advisory was published by ICS-CERT implying the vulnerability exists within an Industrial Control System or similar operational technology environment. This flaw allows a malicious actor to bypass standard authentication mechanisms and directly access sensitive data stored within production storage containers, potentially causing significant data breaches and operational disruption. Defenders should prioritize identifying devices using default credentials, especially in OT environments where a compromise could have physical consequences.

Attack Chain

1. Attacker gains access to the mobile application or device firmware through reverse engineering or by acquiring a compromised device.
2. Attacker extracts the hardcoded storage credentials from the mobile app or firmware.
3. Attacker leverages the extracted credentials to authenticate directly with the production storage container.
4. Due to the lack of adequate permission restrictions, the attacker gains read/write access to sensitive data within the storage container.
5. Attacker accesses sensitive data like configurations, process data, or customer data.
6. Attacker modifies sensitive data like configurations causing a denial of service, or operational disruption.
7. Attacker gains complete control over the storage container and potentially linked resources.
8. The attacker exfiltrates sensitive data or uses it to further compromise the ICS/OT environment.

Impact

Successful exploitation of CVE-2025-10681 could lead to unauthorized access to critical production data, system configurations, and potentially other sensitive information. Depending on the scope of the storage container’s access, attackers could disrupt industrial processes, steal intellectual property, or hold data for ransom. Since this vulnerability relates to ICS/OT environments, compromise of production data could lead to equipment damage, environmental hazards, or safety issues.

Recommendation

• Implement the detection rule Detect Hardcoded Credentials in Mobile App/Firmware Unpacking to detect attempts to unpack or analyze application binaries or firmware images that may contain hardcoded credentials (logsource: file_event, process_creation).
• Examine network traffic for authentication attempts to storage resources using unusual user agents or originating from unusual IP addresses that might indicate credential compromise, using the detection rule Detect Unusual Authentication to Storage Resources. (logsource: network_connection)
• Review and update mobile application and device firmware development practices to eliminate the use of hardcoded credentials, referencing CWE-798 (Use of Hard-coded Credentials).
• Monitor file access and modifications to production storage containers, looking for unusual activity that might indicate unauthorized access following exploitation of CVE-2025-10681 (logsource: file_event).
• Use vulnerability scanning tools to identify devices and applications vulnerable to CVE-2025-10681.
