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

Attack Vector: Local: The vulnerable system 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 through terminal emulation (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., using social engineering techniques to trick a legitimate user into opening a malicious document).
Attack Complexity: Low: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: None: There is no loss of confidentiality within the Vulnerable System.
Vulnerable system 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 to the Vulnerable System.
Vulnerable system 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 Vulnerable System 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 Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system 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 to the Subsequent System.
Subsequent system 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 Subsequent System 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 Subsequent System.

Exploitation evidence

Disclosed: evidence found.
CVE published 10 Dec 2025
Detectable: no evidence on record.
No public nuclei template indexed

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

Update usbmuxd to the fixed version at or beyond commit 3ded00c9985a5108cfc7591a309f9a23d57a8cba as soon as it becomes available to ensure the path traversal flaw is patched.
Restrict local user permissions rigorously to minimize the number of users who can interact with usbmuxd or execute code in its context.
Employ mandatory access controls (e.g., SELinux, AppArmor) to limit usbmuxd’s filesystem access scope, preventing unauthorized directory traversal even if exploited.
Monitor system logs and usbmuxd activity for unusual file access patterns or privilege escalations indicative of exploitation attempts.
Isolate systems running usbmuxd in segmented network zones to reduce the impact of a compromised host.
Educate system administrators and users about the risk of local privilege escalation vulnerabilities and enforce strict access controls on multi-user systems.
Consider deploying host-based intrusion detection systems (HIDS) to detect anomalous behavior related to usbmuxd processes.
If immediate patching is not feasible, temporarily disable or restrict usbmuxd usage on non-critical systems to reduce exposure.

Description

A Path Traversal vulnerability in usbmuxd allows local users to escalate to the service user.This issue affects usbmuxd: before 3ded00c9985a5108cfc7591a309f9a23d57a8cba.

Impact

For European organizations, the primary impact of CVE-2025-66004 lies in the potential for local attackers to escalate privileges on systems running vulnerable versions of usbmuxd. This could lead to unauthorized access to sensitive files, modification of system configurations, or further lateral movement within internal networks. Industries relying on Apple device integration with Linux systems—such as software development firms, mobile device management providers, and enterprises with mixed OS environments—are at particular risk. The vulnerability could undermine confidentiality by exposing sensitive data and integrity by allowing unauthorized changes. Although the attack requires local access, insider threats or compromised user accounts could exploit this flaw. The medium severity indicates a moderate risk, but the absence of user interaction and authentication requirements increases the likelihood of exploitation once local access is obtained. Disruption of device communication services could also affect operational availability in environments dependent on usbmuxd for device connectivity. Overall, the vulnerability poses a tangible risk to European organizations with relevant infrastructure, necessitating timely mitigation to prevent privilege escalation and data breaches.

Variant weaknessOWASP Top 10 A01:2021: Broken Access Control (opens in a new tab)
The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize '.../...//' (doubled triple dot slash) 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).
