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

Detectable: no evidence on record.

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

Organizations should immediately implement input validation and parameterized queries or prepared statements within their Yonyou KSOA 9.0 deployments to prevent SQL injection. If source code modification is not feasible, deploying a web application firewall (WAF) with custom rules to detect and block malicious SQL injection payloads targeting the folderid parameter is recommended. Network segmentation and strict access controls should be enforced to limit exposure of the affected application to untrusted networks. Monitoring and logging of database queries and web requests can help detect exploitation attempts early. Organizations should also engage with Yonyou for official patches or updates and consider upgrading to a newer, patched version once available. Regular security assessments and penetration testing focused on injection flaws are advised to identify and remediate similar vulnerabilities proactively.

Description

A vulnerability was found in Yonyou KSOA 9.0. The affected element is an unknown function of the file /kmf/edit_folder.jsp of the component HTTP GET Parameter Handler. Performing a manipulation of the argument folderid results in sql injection. The attack can be initiated remotely. The exploit has been made public and could be used. 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 severe consequences for affected organizations. Exploitation could lead to unauthorized disclosure of sensitive business data, modification or deletion of critical records, and potential disruption of service availability. Attackers could leverage this flaw to escalate privileges within the database, pivot to other internal systems, or implant persistent backdoors. Given that Yonyou KSOA is an enterprise platform used primarily in China and other Asian markets, organizations in these regions are at higher risk. The lack of vendor response and patch availability increases the window of exposure, potentially inviting targeted attacks or opportunistic exploitation. The vulnerability undermines trust in the affected systems and could result in regulatory penalties if sensitive data is compromised.

Summary

CVE-2026-1132 is a SQL injection vulnerability identified in Yonyou KSOA version 9.0, a widely used enterprise application platform. The vulnerability resides in the HTTP GET parameter handler of the /kmf/edit_folder.jsp file, specifically in the folderid parameter. An attacker can remotely manipulate this parameter to inject malicious SQL queries without requiring authentication or user interaction. This allows unauthorized access to backend databases, potentially leading to data leakage, unauthorized data modification, or denial of service. The vulnerability has a CVSS 4.0 base score of 6.9, reflecting medium severity, with network attack vector, low attack complexity, and no privileges or user interaction needed. Despite early vendor notification, no patches or mitigations have been released, and a public exploit is available, increasing the risk of exploitation. The vulnerability affects the confidentiality, integrity, and availability of the system's data, posing a significant risk to organizations relying on Yonyou KSOA 9.0 for critical business operations.
