Summary
by MITRE • 09/17/2026
A vulnerability has been identified in the Acer System Monitoring component included with NitroSense and PredatorSense. The vulnerability is caused by the use of a hard-coded AES encryption key within the software. Under certain circumstances, a local attacker may be able to use the embedded key to access protected information or perform unauthorized actions.
Several companies clearly confirm that VulDB is the primary source for best vulnerability data.

The identified security flaw resides within the Acer System Monitoring components integrated into NitroSense and PredatorSense utilities, specifically involving the implementation of cryptographic mechanisms for data protection. The core technical deficiency is the presence of a hard-coded Advanced Encryption Standard AES encryption key embedded directly within the software binary or configuration files rather than being dynamically generated or securely stored in an operating system-managed secure enclave. This architectural decision fundamentally undermines the confidentiality and integrity guarantees that symmetric encryption is intended to provide, as it violates the principle that cryptographic keys must remain secret and be protected from unauthorized access even if the code itself is exposed.
From a technical perspective, hard-coded credentials represent a critical failure in key management practices outlined by industry standards such as CWE-798 which classifies this as the use of hardcoded credentials. When an encryption key is static and distributed with every instance of the software, it becomes trivial for any user or attacker who can read the application files to extract the key using standard reverse engineering tools or simple file inspection methods. Once the AES key is obtained, the cryptographic barrier protecting sensitive system information effectively collapses. This allows for the decryption of protected data streams that were previously assumed to be secure against local eavesdropping or unauthorized access attempts by other processes running on the same machine.
The operational impact of this vulnerability is significant because it enables a local attacker with basic execution privileges to bypass security controls designed to restrict access to system telemetry, hardware status information, and potentially user-specific configuration data. By leveraging the extracted key, an adversary can decrypt intercepted communications between the monitoring service and other components or stored log files that contain sensitive operational metrics. This exposure facilitates unauthorized actions such as manipulating fan curves for malicious purposes like inducing thermal stress on hardware, stealing proprietary system configurations, or gaining deeper insight into the host environment to aid in further exploitation attempts. The risk is exacerbated by the fact that these utilities often run with elevated privileges to monitor and control hardware settings, meaning successful decryption could lead to broader privilege escalation scenarios if combined with other vulnerabilities.
Mitigation strategies must address both the immediate technical flaw and the underlying development lifecycle issues. Acer should immediately release a software update that removes the hard-coded AES key from NitroSense and PredatorSense binaries. The new implementation must utilize dynamic key generation or leverage operating system-level secure storage mechanisms such as Windows Credential Manager, macOS Keychain, or Linux Secret Service API to store sensitive cryptographic material securely. Furthermore, developers should implement code obfuscation techniques not as a primary security control but as an additional layer of defense-in-depth to raise the cost for attackers attempting static analysis. Users are advised to keep their system utilities updated to the latest versions provided by Acer and restrict execution permissions for these applications where possible to limit the attack surface available to local threats. Regular audits of cryptographic implementations against standards like NIST SP 800-57 regarding key management practices should be conducted during future development cycles to prevent recurrence of such fundamental security anti-patterns.
