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: 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: 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

These include restricting network access to the affected CMS system by limiting exposure to trusted internal networks or VPNs only. Employ web application firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the strTBName parameter or suspicious requests to /Easy7/apps/WebService/GetDBData.jsp. Conduct thorough input validation and sanitization at the application or proxy level if possible. Monitor logs for unusual database query patterns or repeated access attempts to the vulnerable endpoint. Consider isolating or segmenting the CMS system to reduce potential lateral movement. Organizations should also plan for rapid patch deployment once the vendor releases an official fix. Regular backups of the CMS database and configurations should be maintained to enable recovery in case of compromise.

Description

A flaw has been found in Tiandy Easy7 CMS Windows 7.17.0. Impacted is an unknown function of the file /Easy7/apps/WebService/GetDBData.jsp. This manipulation of the argument strTBName causes sql injection. The attack may be initiated remotely. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

Impact

The SQL injection vulnerability allows attackers to execute arbitrary SQL commands on the backend database of Tiandy Easy7 CMS Windows 7.17.0. This can lead to unauthorized disclosure of sensitive information, unauthorized modification or deletion of data, and potential disruption of service. For organizations, this could mean exposure of confidential surveillance data, manipulation of system configurations, or complete compromise of the CMS environment. Given that the vulnerability requires no authentication and can be exploited remotely, attackers can leverage this flaw to gain footholds in networks, escalate privileges, or move laterally within an organization. The absence of vendor patches increases the risk of exploitation, especially since proof-of-concept exploits are publicly available. This could impact organizations relying on Tiandy Easy7 CMS for video management or security monitoring, potentially undermining physical security and data integrity.

Summary

CVE-2026-3818 identifies a SQL injection vulnerability in Tiandy Easy7 CMS Windows version 7.17.0, located in the /Easy7/apps/WebService/GetDBData.jsp endpoint. The flaw is due to insufficient input validation of the strTBName parameter, which is directly used in SQL queries without proper sanitization or parameterization. This allows an unauthenticated remote attacker to inject arbitrary SQL commands, potentially leading to unauthorized data access, data modification, or database corruption. The vulnerability can be exploited remotely without any user interaction or privileges, increasing its risk profile. The vendor was notified early but has not issued any response or patch, leaving systems exposed. Although no active exploitation has been reported, the public availability of an exploit increases the likelihood of attacks. The CVSS 4.0 vector indicates network attack vector, low attack complexity, no privileges or user interaction required, and impacts on confidentiality, integrity, and availability at a low level, resulting in a medium overall severity score of 6.9. The lack of vendor response and patch availability necessitates immediate defensive measures by users of the affected product version.
