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

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, 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: 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: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 15 Jul 2024
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 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

Until an official patch is released, organizations should implement strict network-level access controls to limit exposure of Tmall_demo instances to trusted internal networks only. Employing web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting sensitive endpoints can reduce attack surface. Conduct thorough code reviews and penetration testing focused on access control mechanisms within Tmall_demo deployments to identify and remediate similar weaknesses. Monitor logs for unusual access patterns or repeated unauthorized attempts to access sensitive data. If feasible, disable or restrict features or endpoints known to expose sensitive information until a fix is available. Engage with the software vendor or community to obtain updates or workarounds. Additionally, ensure that sensitive data is encrypted at rest and in transit to minimize the impact of potential data exposure. Maintain an incident response plan ready to address any data breach resulting from exploitation of this vulnerability.

Description

An access control issue in Tmall_demo v2024.07.03 allows attackers to obtain sensitive information.

Impact

The primary impact of CVE-2024-40554 is the unauthorized disclosure of sensitive information, which can lead to privacy violations, intellectual property theft, or leakage of business-critical data. Since the vulnerability does not affect integrity or availability, it does not enable data modification or service disruption directly. However, the confidentiality breach alone can have severe consequences, including regulatory non-compliance, reputational damage, and potential financial losses. Organizations using Tmall_demo in environments processing sensitive or personal data are at heightened risk. Attackers exploiting this vulnerability can gain insights into internal configurations or user data, which may facilitate further attacks such as phishing, social engineering, or lateral movement within networks. The ease of exploitation without authentication or user interaction increases the likelihood of automated scanning and exploitation attempts once the vulnerability becomes widely known. The lack of available patches means affected organizations must rely on compensating controls to mitigate risk temporarily.

Architecture and Design · Separation of Privilege
Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
