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

Restrict local access to HarmonyOS devices, ensuring only trusted users can interact with the office service.
Implement strict endpoint security controls to prevent unauthorized local access or execution of malicious inputs.
Monitor logs and file system activity for unusual path traversal patterns, especially sequences containing '\..\' or similar traversal indicators.
Educate users about the risks of interacting with untrusted files or inputs that could trigger the vulnerability.
Coordinate with Huawei for timely patch deployment once available; maintain close vendor communication for updates.
Employ application whitelisting or sandboxing for the office service to limit the impact of potential exploitation.
Conduct regular vulnerability assessments on HarmonyOS devices to detect and remediate potential exploitation attempts.
Consider network segmentation to isolate critical HarmonyOS devices from broader enterprise networks to contain potential DoS impacts.

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 of CVE-2025-58291 is the potential denial of service on Huawei HarmonyOS devices running the affected versions. This could disrupt business operations relying on the office service, particularly in environments where HarmonyOS devices are integrated into workflows or critical communication. Although the vulnerability does not compromise data confidentiality or integrity, availability interruptions can lead to productivity losses and operational delays. Organizations with Huawei device deployments in sectors such as telecommunications, manufacturing, or government may face increased risk. The low severity and requirement for local access and user interaction limit the attack surface, but insider threats or compromised endpoints could exploit this vulnerability. The absence of known exploits reduces immediate risk, but the lack of patches necessitates proactive mitigation to avoid potential exploitation as threat actors develop attack methods.

CWE-29Path Traversal: '\..\filename' (opens in a new tab)
Variant weakness
The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize '\..\filename' (leading backslash dot dot) sequences that can resolve to a location that is outside of that directory.
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 · 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).
