CVE-2026-9650 in EasyLogic T150 Remote Terminal Unit & Controller
Summary
by MITRE • 06/25/2026
CWE-522 Insufficiently Protected Credentials vulnerability that could cause unauthorized access and exposure of sensitive information when unauthenticated attacker accesses credentials stored within firmware or system files. With this credential an attacker could subsequently compromise the device if they have physical access to the device.

The CWE-522 vulnerability represents a critical weakness in system security where credentials are inadequately protected within firmware or system files, creating pathways for unauthorized access and information exposure. This vulnerability specifically targets the insufficient protection mechanisms that govern how authentication credentials are stored and managed within embedded systems and firmware environments. When an unauthenticated attacker gains access to these unprotected credentials, they can exploit them to compromise device integrity and functionality.
The technical flaw underlying CWE-522 stems from inadequate cryptographic protection measures applied to sensitive credential storage mechanisms. Credentials stored in firmware or system files often lack proper encryption, access controls, or obfuscation techniques that would prevent unauthorized extraction. This vulnerability typically manifests when developers fail to implement robust protection schemes such as secure key derivation functions, hardware security modules, or encrypted credential containers. The weakness becomes particularly pronounced when physical access to devices is possible, as attackers can directly examine memory dumps, firmware images, or system files where credentials may be stored in plaintext or weakly encrypted formats.
The operational impact of CWE-522 vulnerabilities extends beyond simple unauthorized access to encompass complete device compromise and potential network infiltration. When attackers successfully extract credentials from protected storage mechanisms, they can authenticate as legitimate users or system components, potentially gaining administrative privileges or access to connected networks. This threat is particularly severe in IoT environments where devices may be deployed in physically accessible locations, making them vulnerable to direct hardware manipulation. The vulnerability creates persistent security risks that remain active until the underlying protection mechanisms are properly implemented.
Mitigation strategies for CWE-522 vulnerabilities must address both the immediate credential protection requirements and broader system security architecture considerations. Organizations should implement strong encryption algorithms with appropriate key lengths for credential storage, utilize hardware security modules or trusted execution environments where possible, and establish robust access control policies for sensitive data. The implementation of secure credential management practices including regular credential rotation, use of salted hashes, and proper key derivation functions aligns with industry standards and best practices. Additionally, system designs should incorporate defense-in-depth principles that ensure credential protection even if one layer of security is compromised.
This vulnerability type corresponds to several ATT&CK framework techniques including credential access through the use of valid accounts and bypassing security controls. The attack surface for CWE-522 is particularly relevant in environments where physical security measures are inadequate, such as industrial control systems, medical devices, or automotive systems where firmware-level access can lead to complete system compromise. Security professionals should conduct regular vulnerability assessments focusing on credential storage mechanisms and implement continuous monitoring to detect potential unauthorized access attempts to protected credential repositories.
