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: High: The attacker requires privileges that provide significant (e.g., administrative) control over the vulnerable system allowing full access to the vulnerable system’s settings and files.
User Interaction: Passive: Successful exploitation of this vulnerability requires limited interaction by the targeted user with the vulnerable system and the attacker’s payload. These interactions would be considered involuntary and do not require that the user actively subvert protections built into the vulnerable system.
Vulnerable system confidentiality: None: There is no loss of confidentiality within 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: 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), 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

To mitigate CVE-2025-15451, organizations should first verify if they are running affected versions (4.0 to 4.9) of xnx3 wangmarket. Employing a web application firewall (WAF) with custom rules to detect and block suspicious payloads targeting this parameter can reduce exploitation risk. Restrict administrative access to trusted IP addresses and enforce multi-factor authentication to limit the potential for attackers to gain the necessary privileges. Regularly audit administrative actions and monitor logs for anomalous behavior indicative of attempted XSS exploitation. Additionally, organizations should engage with the vendor for updates and consider upgrading to future patched versions once available. Educating administrators about the risks of clicking untrusted links or executing unknown scripts can also help mitigate user interaction requirements.

Description

A security flaw has been discovered in xnx3 wangmarket up to 4.9. Affected by this issue is some unknown functionality of the file /admin/system/variableSave.do of the component System Variables Page. Performing a manipulation of the argument Description results in cross site scripting. The attack may be initiated remotely. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.

Impact

The primary impact of CVE-2025-15451 is the potential for attackers with administrative privileges to execute arbitrary scripts within the context of the affected application. This can lead to session hijacking, unauthorized actions performed on behalf of legitimate users, or the injection of malicious content that compromises user trust and application integrity. While the vulnerability does not directly compromise confidentiality or availability, it undermines the integrity of the administrative interface and could serve as a stepping stone for more severe attacks. Organizations relying on xnx3 wangmarket for e-commerce or administrative functions may face reputational damage, data manipulation, or unauthorized configuration changes if this vulnerability is exploited. The requirement for high privileges and user interaction limits the attack surface but does not eliminate risk, especially in environments with multiple administrators or less stringent access controls.

Summary

CVE-2025-15451 identifies a cross-site scripting vulnerability in the xnx3 wangmarket product, specifically in versions 4.0 through 4.9. The vulnerability resides in the /admin/system/variableSave.do endpoint, part of the System Variables Page component. The issue arises from insufficient sanitization or validation of the Description parameter, which an attacker can manipulate to inject malicious JavaScript code. This XSS flaw is remotely exploitable but requires the attacker to have high privileges (PR:H) and user interaction (UI:P), indicating that the attacker must be an authenticated user with elevated rights and that some user action is necessary to trigger the payload. The CVSS 4.0 base score is 4.8, reflecting a medium severity level due to the limited scope and required conditions. The vulnerability does not affect confidentiality or availability significantly but impacts integrity and user trust by enabling script execution in the context of an administrative session. The vendor was notified early but has not issued a patch or response, and no known exploits have been observed in the wild to date. This vulnerability could be leveraged for session hijacking, defacement, or further privilege escalation if combined with other flaws.
