Integrity: Low
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: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: None: There is no loss of confidentiality within the impacted component.
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: 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 7 May 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: 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
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
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 29 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.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), 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

Until an official fix is available, restrict local access to trusted users only and monitor for suspicious DLL loading behavior related to uSmartViewServiceAgent.exe. Avoid running untrusted code on affected systems.

Description

ZTE ZXCLOUD iRAI's Cloud PC client uSmartView contains a DLL hijacking vulnerability (CWE-427). The vulnerable process, uSmartViewServiceAgent.exe, runs with SYSTEM privileges, allowing a local attacker to execute arbitrary code, escalate privileges, and potentially cause memory corruption. The vulnerability affects version ZXCLOUD-iRAI-ClientV7.2X. The CVSS 3.1 base score is 5.7 (medium severity). No patch or official remediation guidance is currently available, and no known exploits are reported in the wild.

Impact

Successful exploitation enables a local attacker to execute arbitrary code with SYSTEM privileges, leading to privilege escalation and potential memory corruption. This can compromise system integrity and availability. There is no indication of confidentiality impact. No known exploits are reported in the wild at this time.

Summary

CVE-2026-44406 is a DLL hijacking vulnerability in ZTE's ZXCLOUD iRAI Cloud PC client uSmartView, specifically in the uSmartViewServiceAgent.exe process which runs with SYSTEM privileges. This uncontrolled search path element (CWE-427) allows a local attacker to place a malicious DLL that the service agent loads, resulting in local arbitrary code execution, privilege escalation, and memory corruption. The vulnerability affects version ZXCLOUD-iRAI-ClientV7.2X. The CVSS 3.1 vector indicates local attack vector with low complexity, no privileges required, no user interaction, scope changed, no confidentiality impact, low integrity impact, and high availability impact.

CWE-427Uncontrolled Search Path Element (opens in a new tab)
Base weaknessOWASP Top 10 A08:2025: Software or Data Integrity Failures (opens in a new tab)
The product uses a fixed or controlled search path to find resources, but one or more locations in that path can be under the control of unintended actors.
Architecture and Design · Implementation · Attack Surface Reduction
Hard-code the search path to a set of known-safe values (such as system directories), or only allow them to be specified by the administrator in a configuration file. Do not allow these settings to be modified by an external party. Be careful to avoid related weaknesses such as CWE-426 and CWE-428.
Implementation · Attack Surface Reduction
When invoking other programs, specify those programs using fully-qualified pathnames. While this is an effective approach, code that uses fully-qualified pathnames might not be portable to other systems that do not use the same pathnames.
Implementation · Attack Surface Reduction
Remove or restrict all environment settings before invoking other programs. This includes the PATH environment variable, LD_LIBRARY_PATH, and other settings that identify the location of code libraries, and any application-specific search paths.
