A security flaw has been discovered in Yonyou KSOA 9.0. Affected by this vulnerability is an unknown functionality of the file /worksheet/work_report.jsp of the component HTTP GET Parameter Handler. Performing a manipulation of the argument ID results in SQL injection. Remote exploitation of the attack is possible. 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.
This vulnerability allows attackers to execute arbitrary SQL queries against the database, potentially leading to unauthorized data access or manipulation. The severity level, classified as medium with a CVSS score of 5.5, indicates the need for organizations to address this issue promptly.
Risk to organizations includes potential data breaches, loss of sensitive information, and significant operational impact due to exploitation of this vulnerability. Organizations should prioritize patching immediately.
Given the public availability of the exploit, it is crucial for organizations using Yonyou KSOA to assess their exposure and apply necessary mitigations as part of their security posture.
Vulnerability Details
The vulnerability in Yonyou KSOA is characterized by an SQL injection flaw that can be triggered through improper handling of HTTP GET parameters. The affected version is Yonyou KSOA 9.0, published on January 18, 2026. The CWE classifications for this vulnerability include CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component) and CWE-89 (SQL Injection).
Technical Analysis
The root cause of this vulnerability stems from the inadequate validation of user input in the HTTP GET request. Attackers may exploit this flaw by manipulating the ID parameter to inject SQL statements directly into the database query, allowing for unauthorized data access and manipulation.
The attack vector is remote, with a low attack complexity, meaning that no special knowledge or skills are required to successfully exploit this vulnerability. Privileges required are none, and user interaction is not necessary.
The potential impacts of this vulnerability include low confidentiality, integrity, and availability impacts, as attackers could potentially view, alter, or delete critical data.
Risk & Impact Analysis
Organizations using Yonyou KSOA 9.0 face significant risks due to this vulnerability. The blast radius can be extensive, depending on the data contained within the affected application. Given the medium severity rating, organizations should address this vulnerability in their priority patch cycle.
The current exploitability status indicates that this vulnerability is not part of the Known Exploited Vulnerabilities (KEV) catalog, but the availability of a public exploit emphasizes the urgency for defenders to take action.
Organizations should schedule remediation as part of their regular security assessments and ensure that their systems are protected against potential exploitation.
