The vulnerability has been assigned a CVSS score of 5.5, indicating a medium severity level. Organizations should prioritize remediation to mitigate the risk posed by this vulnerability.
Given the nature of the vulnerability, organizations should schedule remediation urgently to prevent exploitation.
Vulnerability Details
The vulnerability is categorized as a SQL injection issue, specifically affecting the Yonyou KSOA 9.0 platform. The CVSS score of 5.5 reflects a medium severity, indicating that while the vulnerability is not critical, it still poses a significant risk, especially when exploited remotely.
The attack vector is classified as NETWORK, with low attack complexity, meaning that minimal skill is required to exploit this vulnerability. No user interaction is needed, and no privileges are required to execute the attack.
The official CVE description states that the vulnerability allows for remote SQL injection, potentially leading to unauthorized access and manipulation of data within the affected system.
Technical Analysis
The root cause of the vulnerability lies in improper handling of HTTP GET parameters within the Yonyou KSOA platform. Specifically, the manipulation of the 'ID' argument within the /worksheet/work_info.jsp file allows attackers to inject malicious SQL queries.
The attack vector is remote, allowing attackers to exploit the vulnerability from anywhere over the network. The attack complexity is low, as attackers do not need special privileges or user interaction to exploit the vulnerability.
The impacts of successful exploitation include low confidentiality, integrity, and availability impacts, which means that while sensitive data may be exposed, the overall system may remain operational.
Risk & Impact Analysis
Risk to organizations includes potential unauthorized access to sensitive data, manipulation of the database, and overall compromise of the application integrity. The blast radius could be significant depending on the deployment context of the Yonyou KSOA platform.
Organizations must assess the urgency of this vulnerability based on the CVSS score of 5.5, indicating a medium risk. Immediate action is advisable to address this vulnerability and prevent potential exploitation.
Given the exploit maturity is classified as proof-of-concept, there is a heightened risk of exploitation in the wild, emphasizing the need for prompt remediation.
