Integrity: None
Availability: Low

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

Attack Vector: Local: The vulnerable component is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either: the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or remotely (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., tricking a legitimate user into opening a malicious document).
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: None: There is no loss of confidentiality within the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 11 Oct 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
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 channels for patches or updates addressing CVE-2025-58290 and apply them promptly once available.
Limit local access to devices running affected HarmonyOS versions by enforcing strict physical and logical access controls, including device lock policies and user authentication.
Educate users about the risk of interacting with untrusted content or applications that might trigger the vulnerability, reducing the likelihood of successful exploitation.
Implement endpoint detection and response (EDR) solutions capable of monitoring and alerting on abnormal behavior or crashes in the office service.
Consider network segmentation to isolate critical devices running HarmonyOS, minimizing the impact of any local compromise.
Maintain regular backups of critical data and configurations to enable rapid recovery in case of service disruption.
Conduct periodic security assessments of Huawei device deployments to identify and remediate potential weaknesses related to local access and user interaction.

Description

Denial of service (DoS) vulnerability in the office service. Successful exploitation of this vulnerability may affect availability.

Impact

For European organizations, the primary impact is service disruption of office-related functionalities on Huawei HarmonyOS devices, potentially affecting productivity and operational continuity. Since the vulnerability requires local access and user interaction, remote exploitation is unlikely, reducing the risk of widespread attacks. However, organizations with Huawei device deployments in corporate or governmental environments could face targeted attempts to disrupt availability. The impact is more pronounced in sectors relying heavily on Huawei's HarmonyOS ecosystem for office services, such as telecommunications, public administration, and enterprises with Huawei-based mobile or IoT devices. Disruptions could lead to temporary loss of access to critical office applications, affecting workflows and collaboration. Given the low severity, the overall risk is moderate but should be managed proactively to avoid escalation or exploitation in combination with other vulnerabilities.

CWE-41Improper Resolution of Path Equivalence (opens in a new tab)
Base weakness
The product is vulnerable to file system contents disclosure through path equivalence. Path equivalence involves the use of special characters in file and directory names. The associated manipulations are intended to generate multiple names for the same object.
Implementation · Input Validation
Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
Implementation · Output Encoding
Use and specify an output encoding that can be handled by the downstream component that is reading the output. Common encodings include ISO-8859-1, UTF-7, and UTF-8.
Implementation · Input Validation
Inputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180). Make sure that the application does not decode the same input twice (CWE-174).
