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

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

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-2025-15436, organizations should immediately implement input validation and sanitization for the Report parameter and any other user-controllable inputs in the /worksheet/work_edit.jsp file. Employing parameterized queries or prepared statements is critical to prevent SQL injection attacks. Network-level protections such as web application firewalls (WAFs) should be configured to detect and block SQL injection patterns targeting this endpoint. Continuous monitoring and logging of database queries can help identify suspicious activities indicative of exploitation attempts. Organizations should isolate the affected system segments and restrict access to trusted users and networks where possible. Additionally, conducting regular security assessments and penetration testing focused on injection flaws will help identify and remediate similar vulnerabilities proactively.

Description

A vulnerability has been found in Yonyou KSOA 9.0. Affected by this issue is some unknown functionality of the file /worksheet/work_edit.jsp. Such manipulation of the argument Report leads to sql injection. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

Impact

The potential impact of CVE-2025-15436 is significant for organizations using Yonyou KSOA 9.0. Successful exploitation can lead to unauthorized access to sensitive business data, data corruption, or deletion, which can disrupt critical business operations. Confidentiality breaches could expose proprietary or personal information, leading to regulatory compliance issues and reputational damage. Integrity violations may result in incorrect business decisions based on tampered data. Availability impacts, while limited, could arise if injected queries cause database errors or crashes. Since the vulnerability requires no authentication and can be exploited remotely, attackers can launch attacks from anywhere, increasing the threat surface. The absence of vendor patches and public exploit disclosures heighten the urgency for organizations to implement mitigations. Industries relying heavily on Yonyou KSOA, such as manufacturing, finance, and government sectors in affected regions, face elevated risks of targeted attacks and data compromise.

Summary

CVE-2025-15436 is a SQL injection vulnerability identified in Yonyou KSOA version 9.0, a widely used enterprise resource planning (ERP) and office automation software suite. The vulnerability resides in the /worksheet/work_edit.jsp file, where the Report parameter is improperly sanitized, allowing an attacker to inject malicious SQL code. This injection flaw enables remote attackers to manipulate backend SQL queries without requiring authentication or user interaction, potentially leading to unauthorized data retrieval, modification, or deletion. The CVSS 4.0 base score of 6.9 reflects a medium severity level, considering the ease of exploitation (network accessible, no privileges or user interaction needed) but limited scope of impact (partial confidentiality, integrity, and availability impact). The lack of vendor response increases risk, as unpatched systems remain exposed. Exploitation could lead to data breaches, unauthorized data manipulation, or disruption of business processes relying on the affected database. Given Yonyou's significant market penetration in China and parts of Asia, this vulnerability poses a notable risk to organizations using KSOA 9.0 in those regions.
