A vulnerability was identified in Yonyou KSOA 9.0. Affected is an unknown function of the file /worksheet/work_mod.jsp of the component HTTP GET Parameter Handler. Such manipulation of the argument ID leads to sql injection. The attack may be launched remotely. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.
This vulnerability allows attackers to execute arbitrary SQL queries, which can compromise the integrity and confidentiality of the database. The severity level of this vulnerability is classified as medium with a CVSS score of 5.5.
Risk to organizations includes unauthorized access to sensitive data, data manipulation, and potential disruption of service. Organizations should prioritize patching immediately.
As of the latest update, no known public exploits exist, but the vulnerability's details are readily available, increasing the risk of potential attacks. Immediate action is required to mitigate potential threats.
Vulnerability Details
The vulnerability in Yonyou KSOA is characterized by SQL injection via the HTTP GET Parameter Handler. This allows attackers to manipulate SQL queries through the 'ID' parameter. The CVSS version 4.0 score of 5.5 indicates a medium severity, suggesting that while the vulnerability is exploitable, it may not lead to severe consequences without additional vulnerabilities being present.
Technical Analysis
The root cause of this vulnerability stems from improper validation of user input in the affected component. Attackers may leverage this vulnerability by sending crafted requests to the vulnerable endpoint, exploiting the SQL injection vector.
The attack vector is network-based, and the complexity is low, meaning that no special conditions must be met for an attacker to exploit this vulnerability. It does not require any privileges or user interaction, making it particularly dangerous.
Risk & Impact Analysis
Real-world deployment risks are significant, especially for organizations that handle sensitive information. The potential blast radius includes unauthorized data access and manipulation, which could lead to operational disruptions. Organizations should assess the impact of this vulnerability in their environment and prioritize remediation efforts. Given the CVSS score and the absence of a patch, organizations must evaluate their exposure and act accordingly.
