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

Exploitation evidence

Disclosed: evidence found.
CVE published 2 Jan 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

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 2026-10-26.

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

1. Immediate implementation of web application firewall (WAF) rules to detect and block suspicious SQL injection patterns targeting the 'ID' parameter in /worksheet/del_user.jsp requests. 2. Employ strict input validation and sanitization on all user-supplied parameters, especially the 'ID' parameter, to ensure only expected data types and formats are accepted. 3. Restrict database user permissions for the application to the minimum necessary, preventing unauthorized data manipulation or access beyond what is required. 4. Monitor application and database logs for unusual query patterns or errors indicative of SQL injection attempts. 5. Isolate or segment the affected application environment to limit lateral movement if exploitation occurs. 6. Engage with Yonyou support channels to request official patches or guidance and track for future updates. 7. Consider temporary disabling or restricting access to the vulnerable endpoint if feasible until a patch is available. 8. Conduct thorough security assessments and penetration testing focused on injection flaws in the application. 9. Educate development and operations teams on secure coding practices to prevent similar vulnerabilities in future releases.

Description

A vulnerability was determined in Yonyou KSOA 9.0. The impacted element is an unknown function of the file /worksheet/del_user.jsp of the component HTTP GET Parameter Handler. Executing a manipulation of the argument ID can lead to sql injection. The attack can be executed remotely. The exploit has been publicly disclosed and may be utilized. The vendor was contacted early about this disclosure but did not respond in any way.

Impact

The SQL injection vulnerability in Yonyou KSOA 9.0 can have significant consequences for organizations relying on this software. Attackers exploiting this flaw can remotely execute arbitrary SQL queries, potentially leading to unauthorized data access, data corruption, or deletion. This compromises the confidentiality and integrity of sensitive business data, including user information and operational records. Additionally, the availability of the application or database could be disrupted if destructive queries are executed. Given that no authentication or user interaction is required, automated attacks or mass scanning campaigns could rapidly target vulnerable systems. The lack of vendor response and patches increases the window of exposure, elevating the risk of data breaches and operational disruptions. Organizations may face regulatory compliance issues, reputational damage, and financial losses if exploited. The impact is particularly critical for enterprises with sensitive or regulated data stored in Yonyou KSOA databases.

Summary

CVE-2025-15425 identifies a SQL injection vulnerability in Yonyou KSOA version 9.0, a business management software widely used in enterprise environments. The flaw exists in an unspecified function within the /worksheet/del_user.jsp component, which processes HTTP GET requests. Specifically, the 'ID' parameter is not properly sanitized or validated, allowing an attacker to inject arbitrary SQL commands. This vulnerability can be exploited remotely without any authentication or user interaction, increasing the risk of automated attacks. The SQL injection could enable attackers to read, modify, or delete sensitive data stored in the backend database, potentially compromising the confidentiality, integrity, and availability of critical business information. The vendor was notified early but has not issued a patch or response, and while no known exploits are currently active in the wild, the public disclosure raises the risk of imminent exploitation. The CVSS 4.0 score of 6.9 reflects a medium severity, considering the network attack vector, lack of required privileges, and partial impact on data confidentiality, integrity, and availability. The vulnerability affects only version 9.0 of the product, and no mitigations or patches have been officially released to date.
