A vulnerability was determined in Yonyou KSOA 9.0. The impacted element is an unknown function of the file /kmf/folder.jsp of the component HTTP GET Parameter Handler. Executing a manipulation of the argument folderid can lead to SQL injection. The attack can be launched 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.
This vulnerability has a CVSS base score of 5.5, classified as medium severity, indicating a moderate risk to organizations that utilize this software. The low attack complexity and remote exploitability mean that attackers may exploit this vulnerability without requiring extensive resources or specific conditions.
Organizations should prioritize patching immediately. The potential for SQL injection can lead to unauthorized access, data manipulation, and further exploitation of the underlying system.
As of the latest updates, there is no known public exploit or proof of concept available. However, the existence of a publicly disclosed vulnerability should prompt swift action to mitigate potential risks.
Vulnerability Details
The CVE-2026-1133 vulnerability affects the Yonyou KSOA version 9.0. The CWE classifications associated with this vulnerability include CWE-89 (SQL Injection) and CWE-74 (Injection). The vulnerability was published on January 19, 2026, and is listed as analyzed.
The CVSS vector string indicates that the attack vector is network-based, with low complexity and no privileges required. The confidentiality, integrity, and availability impacts are all rated as low.
Technical Analysis
The root cause of CVE-2026-1133 stems from inadequate input validation in handling HTTP GET parameters. Attackers may manipulate the folderid argument in requests directed at the vulnerable JSP file, resulting in SQL injection. This vulnerability can be exploited without user interaction, allowing for automated attacks.
Given the low attack complexity and absence of required privileges, this vulnerability poses a significant risk to systems using the affected version of Yonyou KSOA. Organizations must be vigilant and implement security measures to detect any abnormal activities related to database interactions.
