Proactive Monitoring: Monitor device access logs for unusual patterns or failed authentication attempts targeting the devicemanager module services.

Compensating Controls: Restrict network access to devices to trusted segments only, as the vulnerability requires an adjacent network position for exploitation.

Exploitation Status

Public Exploit Available: Unknown

Analyst Notes: As of August 7, 2025, there is no public information indicating active exploitation or a public proof-of-concept for this vulnerability. While exploitation requires an adjacent network presence and specific conditions, the potential for total technical impact necessitates prompt attention once vendor patches are released.

Analyst Recommendation

Given the high CVSS score and the nature of the authentication bypass, administrators should prioritize the deployment of security updates for HarmonyOS 5.1.0 and 5.0.1. Organizations using these devices should maintain a heightened state of vigilance and monitor vendor support channels for the release of specific patch identifiers.

Description Summary:
A business logic error in the Gallery module of Huawei HarmonyOS and EMUI allows for unauthorized resource reading, potentially impacting the confidentiality of user data.

Executive Summary:
A business logic vulnerability in the Huawei Gallery module affects multiple versions of HarmonyOS and EMUI, posing a risk to data confidentiality.

Vulnerability Details

CVE-ID: CVE-2025-54611

Affected Software: Huawei HarmonyOS and EMUI

Affected Versions: HarmonyOS 4.3.1, 4.3.0, 4.2.0, 4.0.0, 3.1.0, 3.0.0, 2.1.0, 2.0.0; EMUI 15.0.0, 14.0.0, 13.0.0, 12.0.0

Vulnerability: The vulnerability is a business logic error (CWE-840) within the Gallery module that permits unauthorized resource reading. Based on the CVSS vector (AV:L/PR:N/UI:N), the exploit requires local access to the device but does not require user interaction or elevated privileges to trigger.

Business Impact

The exploitation of this flaw may lead to the unauthorized disclosure of sensitive information stored within the Gallery application. With a CVSS score of 7.3, this is considered a High severity issue, as it compromises the fundamental confidentiality of user assets, potentially leading to privacy violations or exposure of personal media.

Remediation Plan

Immediate Action: Users should check for and apply the latest security updates provided by Huawei through the official system update interface as detailed in the August 2025 security bulletin.

Proactive Monitoring: Security teams or users should monitor for unusual application behavior or unexpected permission requests associated with the Gallery module.

Compensating Controls: Ensure that device-level security features, such as screen locks and file-based encryption, are strictly enforced to limit the potential for unauthorized local access to the device.

Exploitation Status

Public Exploit Available: No

Analyst Notes: As of August 7, 2025, there is no public information indicating active exploitation or a public proof-of-concept for this vulnerability. While the vulnerability is classified as a logic error, the local access requirement limits its reach compared to remote network-based exploits.

Analyst Recommendation

Given the High severity rating, administrators and users must prioritize the deployment of vendor-supplied patches as soon as they become available. Failure to update the affected Huawei devices leaves the Gallery module susceptible to unauthorized data access, and immediate patching is the only effective way to remediate this logic-based exposure.

Description Summary:
The ArkWeb module in Huawei HarmonyOS contains an improper certificate validation vulnerability that may result in compromised service confidentiality.

Executive Summary:
A high-severity authentication management vulnerability in the ArkWeb module of Huawei HarmonyOS could allow attackers to bypass certificate validation and compromise data confidentiality.

Vulnerability Details

CVE-ID: CVE-2025-54607

Affected Software: Huawei HarmonyOS

Affected Versions: 5.1.0, 5.0.1

Vulnerability: The vulnerability is classified as improper certificate validation (CWE-295) within the ArkWeb module. It allows unauthenticated remote attackers to potentially intercept or manipulate secure communications due to the failure to properly verify SSL/TLS certificates.

Business Impact

Successful exploitation of this flaw poses a significant risk to data confidentiality and integrity by allowing man-in-the-middle attacks. Given the CVSS score of 7.7, this is classified as a High severity issue, as it could lead to the exposure of sensitive user information transmitted over affected connections. Organizations relying on HarmonyOS for secure data transit should prioritize remediation to prevent unauthorized data interception.

Remediation Plan

Immediate Action: Update affected Huawei HarmonyOS devices to the version specified in the vendor security bulletin for August 2025.

Proactive Monitoring: Review system and network access logs for unusual traffic patterns or connection errors that may indicate failed certificate handshakes or interception attempts.

Compensating Controls: Ensure that applications utilizing the ArkWeb module enforce strict transport security policies and utilize certificate pinning where possible to mitigate the risk of untrusted certificate acceptance.

Exploitation Status

Public Exploit Available: No (exploit_available: false)

Analyst Notes: As of August 7, 2025, there is no public information indicating active exploitation or a public proof-of-concept for this vulnerability. The vulnerability requires a specific network position to execute, which slightly limits the attack surface despite the high severity rating.

Analyst Recommendation

The presence of an improper certificate validation flaw in a core module like ArkWeb represents a critical security gap for HarmonyOS environments. Administrators must prioritize the deployment of vendor-supplied security patches to resolve this vulnerability. Until updates are applied, minimize exposure by limiting device connectivity to trusted and secured network environments.

Description Summary:
A logic error in the Huawei HarmonyOS lock screen module allows local attackers to bypass status verification, impacting device confidentiality and availability.

Executive Summary:
A high-severity business logic vulnerability in the Huawei HarmonyOS lock screen module allows unauthenticated local attackers to compromise device confidentiality and availability.

Vulnerability Details

CVE-ID: CVE-2025-54606

Affected Software: Huawei HarmonyOS

Affected Versions: 5.0.1

Vulnerability: This vulnerability is classified as a business logic error (CWE-840) within the lock screen module. The flaw permits an unauthenticated local attacker to bypass status verification checks, leading to partial impacts on system confidentiality and availability.

Business Impact

Successful exploitation of this flaw allows a local attacker to access protected information or disrupt system services without proper authorization. Given the CVSS score of 7.3, this issue represents a significant security risk for mobile environments where unauthorized local access could lead to data exfiltration or denial of service.

Remediation Plan

Immediate Action: Users should check for and apply the latest security updates provided by Huawei via the official support bulletin.

Proactive Monitoring: Security teams should monitor device logs for any anomalous activity surrounding lock screen authentication events or unexpected system state changes.

Compensating Controls: Ensure device encryption is enabled and implement strong secondary authentication methods (such as hardware-backed biometric security) to limit the effectiveness of a lock screen bypass.

Exploitation Status

Public Exploit Available: No (exploit_available: false)

Analyst Notes: As of August 7, 2025, there is no public information indicating active exploitation or a public proof-of-concept for this vulnerability. The flaw is locally exploitable and requires physical access to the target device, which limits the attack surface but remains a critical concern for mobile security.

Analyst Recommendation

The vulnerability presents a credible risk to device integrity and user data. Administrators and individual users are urged to monitor the Huawei support portal for patch availability and apply the relevant security updates immediately upon release to remediate this logic flaw.
