Attack Vector: Physical
Attack Complexity: Low
Privileges Required: None
User Interaction: Required
Scope: Unchanged
Confidentiality: High
Integrity: Low
Availability: None

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Physical: The attack requires the attacker to physically touch or manipulate the vulnerable component. Physical interaction may be brief or persistent.
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

Monitor Huawei’s official security advisories and apply patches promptly once they are released for the affected HarmonyOS versions (5.0.1, 5.1.0, 6.0.0).
Restrict network access to HarmonyOS devices, especially from untrusted or public networks, to reduce the attack surface.
Implement strict user awareness training to reduce the risk of social engineering or phishing attacks that could trigger the required user interaction for exploitation.
Employ endpoint detection and response (EDR) solutions capable of monitoring unusual file access patterns or permission escalations on HarmonyOS devices.
Use network segmentation to isolate critical systems and sensitive data from devices running vulnerable OS versions.
Enforce strong access controls and encryption on sensitive files managed by the file management module to add layers of protection beyond OS permissions.
Conduct regular audits of device configurations and permissions to detect and remediate potential misconfigurations that could exacerbate the vulnerability.

Description

CVE-2025-64312 is a medium-severity permission control vulnerability in Huawei HarmonyOS's file management module that can lead to unauthorized exposure of sensitive information. It affects versions 5.0.1, 5.1.0, and 6.0.0. Exploitation requires network access and user interaction but no privileges, potentially compromising confidentiality with limited impact on integrity or availability. No known exploits are currently reported in the wild.

Impact

For European organizations, the primary impact of CVE-2025-64312 is the potential unauthorized disclosure of sensitive information, which could include personal data, intellectual property, or confidential business information. This exposure could lead to privacy breaches, regulatory non-compliance (e.g., GDPR violations), reputational damage, and potential financial losses. Since the vulnerability requires user interaction and network access, targeted phishing or social engineering campaigns could be used to exploit it. The limited impact on integrity and availability reduces the risk of system disruption or data manipulation, but confidentiality breaches alone can have significant consequences, especially in sectors such as finance, healthcare, government, and critical infrastructure. Organizations relying on Huawei HarmonyOS devices for mobile or IoT deployments should be particularly vigilant, as these devices may be used to access or store sensitive corporate data.

MITRE discourages mapping vulnerabilities to this broad entry; the root cause is usually a more specific weakness.
Architecture and Design · Separation of Privilege
Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
