CVE-2026-44103 in CHARX SEC-3150
Summary
by MITRE • 07/30/2026
An unauthenticated remote attacker can inject malicious firmware into the internal charging module because the JupiCore service transmits firmware updates without performing integrity or verification check. Successful exploitation may compromise the integrity of the affected device. This vulnerability could be used in chain with CVE-2026-44104.

This vulnerability represents a critical security flaw in the firmware update mechanism of devices running JupiCore service, where the absence of integrity verification creates an attack vector for remote exploitation. The fundamental technical issue lies in the service's failure to implement proper cryptographic checks or digital signatures during firmware transmission processes, allowing malicious actors to inject unauthorized code into the internal charging module. This weakness directly violates security principles outlined in cwe-353 and cwe-310, which address the importance of data integrity verification and cryptographic strength in system components. The vulnerability exists at the protocol level where firmware update communications lack authentication mechanisms, creating a pathway for attackers to manipulate the update process without requiring any valid credentials or physical access to the device.
The operational impact of this vulnerability extends beyond simple unauthorized code execution, as it fundamentally compromises the device's integrity and potentially its safety mechanisms. When an attacker successfully injects malicious firmware into the charging module, they gain the ability to manipulate power management functions, potentially leading to overheating, battery damage, or even physical hazards. The attack surface is particularly concerning because the charging module typically operates with elevated privileges and direct hardware access, making it a prime target for persistent malware deployment. This vulnerability aligns with att&ck technique T1068 which describes local privilege escalation techniques that can be leveraged through compromised system components. The security implications escalate when considering that such attacks could be chained with CVE-2026-44104, creating a multi-stage exploitation pathway where initial access through one vulnerability enables the deployment of malicious firmware through this integrity check failure.
The mitigation strategy for this vulnerability requires immediate implementation of cryptographic verification mechanisms throughout the firmware update process. Organizations should deploy digital signature validation that ensures all firmware updates are verified against trusted certificates before installation. This approach directly addresses cwe-310 by implementing proper cryptographic protections and aligns with att&ck tactic TA0004 which emphasizes defense in depth through integrity checks. The solution must include certificate pinning mechanisms, secure boot processes, and continuous monitoring of update transactions to detect anomalous behavior. Additionally, network segmentation should be implemented to restrict firmware update access points, ensuring that only authorized endpoints can communicate with the JupiCore service. Device manufacturers should also implement rollback protection measures and maintain detailed audit logs of all firmware modification activities to support forensic analysis in case of successful exploitation attempts.
