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.

CVE published 28 Nov 2025
Detectable: no evidence on record.
No public nuclei template indexed

Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

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 closely and apply patches or updates for HarmonyOS as soon as they become available to remediate the vulnerability.
Restrict network access to devices running affected HarmonyOS versions, especially limiting exposure to untrusted networks or the internet.
Implement strict access controls and permissions on file management operations to minimize the risk of unauthorized access.
Educate users about the risks of social engineering and the need to avoid interacting with suspicious prompts or links that could trigger exploitation.
Deploy network segmentation to isolate Huawei devices from critical systems and sensitive data repositories.
Use endpoint detection and response (EDR) tools to monitor for unusual file access patterns or unauthorized data exfiltration attempts.
Conduct regular security audits and vulnerability assessments focusing on Huawei device deployments to identify and mitigate potential attack vectors.
Consider alternative device or OS options in high-risk environments until the vulnerability is fully addressed.

Description

CVE-2025-58304 is a medium severity permission control vulnerability in the file management module of Huawei's HarmonyOS versions 5.0.1, 5.1.0, and 6.0.0. Exploiting this flaw requires network access and user interaction but no privileges, potentially allowing attackers to compromise service confidentiality. The vulnerability is categorized under CWE-199 (Information Management Errors), indicating improper handling of sensitive information. While no known exploits are currently in the wild, successful exploitation could lead to unauthorized data disclosure.

Impact

For European organizations, the primary impact of CVE-2025-58304 lies in the potential compromise of service confidentiality. Organizations using Huawei devices running the affected HarmonyOS versions—such as smartphones, tablets, or IoT devices—may face unauthorized disclosure of sensitive information managed by the file system. This could include corporate data, personal user information, or configuration files critical to service operation. The vulnerability does not affect integrity or availability significantly, but confidentiality breaches can lead to secondary impacts such as reputational damage, regulatory penalties under GDPR, and loss of competitive advantage. Sectors with high reliance on Huawei technology, including telecommunications, public administration, and critical infrastructure, may be particularly vulnerable. The requirement for user interaction reduces the risk of widespread automated exploitation but does not eliminate targeted attacks, especially spear-phishing or social engineering campaigns. The medium severity rating suggests that while the threat is not critical, it warrants timely attention to prevent escalation or chaining with other vulnerabilities.
