Threat metrics

Exploit Maturity: POC

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

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
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: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the Vulnerable System.
Vulnerable system integrity: None: There is no loss of integrity within the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within 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: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.
Exploit Maturity: POC: Based on threat intelligence sources each of the following must apply: · Proof-of-concept is publicly available · No knowledge of reported attempts to exploit this vulnerability · No knowledge of publicly available solutions used to simplify attempts to exploit the vulnerability

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), CVSS vector, the Metasploit, Exploit-DB and nuclei-templates index as of 30 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

Given the absence of official patches, organizations should implement immediate compensating controls. These include restricting network access to the Tiandy Easy7 management platform using firewalls or network segmentation to limit exposure to trusted administrators only. Employ VPNs or secure tunnels for remote management access to reduce attack surface. Monitor network traffic for suspicious requests targeting /WebService/UpdateLocalDevInfo.jsp and implement intrusion detection/prevention rules to block unauthorized attempts. Regularly audit device configurations and logs for unauthorized changes. If possible, disable or restrict the vulnerable web service endpoint until a vendor patch is available. Engage with Tiandy support channels for updates and consider alternative management solutions if the risk is unacceptable. Maintain up-to-date backups of device configurations to enable recovery from potential tampering.

Description

CVE-2026-4187 is a medium severity vulnerability in Tiandy Easy7 Integrated Management Platform version 7.17.0, involving missing authentication in the /WebService/UpdateLocalDevInfo.jsp component. This flaw allows remote attackers to manipulate username and password parameters without authentication, potentially enabling unauthorized access or device information updates. The vulnerability can be exploited remotely without any user interaction or privileges. Although no known exploits are currently active in the wild, a public exploit exists. The vendor has not responded to disclosure attempts, and no patches are available yet. Organizations using this platform should urgently assess exposure and implement compensating controls to mitigate risk. Countries with significant Tiandy product deployments, especially in Asia, Europe, and North America, are at higher risk.

Impact

The primary impact of CVE-2026-4187 is unauthorized remote access to device management functions without authentication, which can lead to unauthorized modification of device information. This compromises the integrity of device data and potentially the confidentiality of sensitive device identifiers or configurations. Organizations relying on Tiandy Easy7 for surveillance or integrated device management may face risks including unauthorized device control, data tampering, or preparation for further attacks such as lateral movement within networks. The lack of authentication could also facilitate automated attacks at scale. While availability impact is not indicated, the integrity and confidentiality risks are significant, especially in critical infrastructure or security-sensitive environments. The absence of vendor response and patches increases exposure duration, raising the risk of exploitation as threat actors may leverage the public exploit code.

Summary

CVE-2026-4187 affects Tiandy Easy7 Integrated Management Platform version 7.17.0, specifically a missing authentication vulnerability in the Device Identifier Handler component located at /WebService/UpdateLocalDevInfo.jsp. The vulnerability arises from improper validation of username and password parameters, allowing remote attackers to bypass authentication mechanisms entirely. This means an attacker can remotely invoke this function to update or manipulate device information without any credentials or prior access. The vulnerability is exploitable over the network without requiring user interaction or privileges, increasing its risk profile. Although the CVSS 4.0 score is 6.9 (medium), the exploitability is straightforward due to no authentication or user interaction requirements. The vendor was notified early but has not issued any patches or advisories, and no known active exploitation has been reported yet. The availability of a public exploit increases the likelihood of future attacks. This vulnerability could allow attackers to alter device configurations or inject malicious data, potentially undermining the integrity and confidentiality of the surveillance or management infrastructure relying on this platform.
