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: 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 2026-10-26.

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-2025-12290, affected organizations should implement the following specific measures: 1) Apply strict input validation and sanitization on the 'keywords' parameter and any user-supplied input to ensure that scripts or HTML cannot be injected. 2) Employ context-aware output encoding (e.g., HTML entity encoding) before rendering user input in web pages to prevent script execution. 3) Deploy and properly configure a Web Application Firewall (WAF) with rules to detect and block common XSS attack patterns targeting the affected endpoint. 4) Conduct thorough code reviews and security testing of the affected application components to identify and remediate similar vulnerabilities. 5) Educate users and administrators about the risks of clicking untrusted links and monitor logs for suspicious activity indicative of attempted exploitation. 6) If possible, isolate or restrict access to the vulnerable endpoint until a vendor patch or update is available. 7) Engage with the vendor or consider migrating to alternative, actively maintained e-commerce platforms with better security support. 8) Implement Content Security Policy (CSP) headers to reduce the impact of potential XSS attacks by restricting script sources.

Description

CVE-2025-12290 is a medium-severity cross-site scripting (XSS) vulnerability found in version 1.0 of the Suishang Enterprise-Level B2B2C Multi-User Mall System by Sui Shang Information Technology. The vulnerability arises from improper sanitization of the 'keywords' parameter in the /i/359 endpoint, allowing remote attackers to inject malicious scripts. Exploitation does not require authentication but does require user interaction, such as clicking a crafted link. Although no known exploits are currently observed in the wild, the vulnerability has been publicly disclosed and the vendor has not responded to notifications. This flaw could enable attackers to steal session cookies, perform actions on behalf of users, or deliver malware via the affected web application. European organizations using this e-commerce platform may face risks to customer data confidentiality and integrity, as well as reputational damage. Mitigation involves implementing strict input validation and output encoding on the affected parameter, deploying web application firewalls with XSS detection, and monitoring for suspicious activity. Countries with higher adoption of this platform or significant e-commerce sectors, such as Germany, France, and the UK, are more likely to be impacted. Given the ease of remote exploitation without authentication, the vulnerability warrants medium severity classification.

Impact

For European organizations using the Suishang Enterprise-Level B2B2C Multi-User Mall System, this XSS vulnerability poses risks primarily to the confidentiality and integrity of customer data and user sessions. Attackers could hijack user accounts, steal sensitive information such as payment details or personal data, and perform unauthorized actions within the application. This can lead to financial losses, regulatory non-compliance (e.g., GDPR violations), and reputational damage. The vulnerability could also be leveraged to distribute malware or conduct phishing campaigns targeting customers. Given the e-commerce context, trust in the platform is critical, and exploitation could undermine customer confidence. The lack of vendor patching increases exposure duration, requiring organizations to implement compensating controls. While the vulnerability does not directly impact system availability, the indirect effects of compromised user accounts and data breaches can disrupt business operations and customer relations. European organizations with significant online retail presence or handling sensitive customer data are particularly at risk.

Summary

CVE-2025-12290 identifies a cross-site scripting (XSS) vulnerability in the Suishang Enterprise-Level B2B2C Multi-User Mall System version 1.0, specifically within an unspecified functionality tied to the /i/359 endpoint. The vulnerability stems from improper handling of the 'keywords' argument, which allows an attacker to inject malicious JavaScript code that executes in the context of users visiting the affected page. This flaw can be exploited remotely without any authentication, requiring only that a victim interacts with a crafted URL or input. The vulnerability impacts the confidentiality and integrity of user sessions by enabling theft of cookies, session tokens, or other sensitive information, and can facilitate further attacks such as phishing or malware delivery. The vendor was notified but has not issued a patch or response, and while no active exploitation has been reported, the public disclosure increases the risk of exploitation attempts. The CVSS 4.0 score of 5.3 reflects medium severity, considering the attack vector is network-based, no privileges or authentication are required, but user interaction is necessary. The vulnerability does not affect system availability or require complex conditions, making it a moderate risk for organizations relying on this e-commerce platform. The lack of vendor response and patch availability necessitates proactive mitigation by affected parties.
