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: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
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

Exploitation evidence

Disclosed: evidence found.
CVE published 1 Feb 2026
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
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 2026-10-25.

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 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

Organizations should immediately audit their CRMEB installations to identify affected versions (5.6.0 to 5.6.3). In the absence of an official patch, implement strict access control checks on the /api/store_integral/order/detail/:uni endpoint to ensure order_id parameters are validated against the requesting user's permissions. Employ web application firewalls (WAFs) to detect and block suspicious requests targeting this endpoint, especially those with unusual or out-of-context order_id values. Monitor logs for anomalous access patterns or repeated attempts to access unauthorized order details. Restrict API access to trusted networks or authenticated users where possible, even if the vulnerability does not require authentication. Engage with Zhong Bang for updates or patches and plan for timely upgrades once available. Additionally, conduct security awareness training for developers and administrators to recognize and remediate improper authorization issues in custom or third-party applications.

Description

A vulnerability was identified in Zhong Bang CRMEB up to 5.6.3. This affects the function detail/tidyOrder of the file /api/store_integral/order/detail/:uni. The manipulation of the argument order_id leads to improper authorization. The attack can be initiated remotely. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.

Impact

The primary impact of CVE-2026-1733 is unauthorized disclosure of order-related data, which can include sensitive customer and transactional information. This can lead to privacy violations, loss of customer trust, and potential regulatory compliance issues, especially in jurisdictions with strict data protection laws. Attackers exploiting this vulnerability could gather intelligence on business operations or customer purchasing behavior. Although the vulnerability does not directly affect system integrity or availability, the confidentiality breach alone can have significant reputational and financial consequences. Since exploitation requires no authentication and can be performed remotely, the attack surface is broad. Organizations worldwide using Zhong Bang CRMEB in e-commerce or retail sectors are at risk, particularly those with high volumes of sensitive order data. The availability of a public exploit increases the risk of automated scanning and exploitation attempts.
