A security vulnerability has been detected in youlaitech youlai-boot up to version 2.21.1. This vulnerability allows for SQL injection through the function getUserList of the file src/main/java/com/youlai/boot/system/controller/UserController.java, specifically in the component Users Endpoint. The manipulation of the argument order can be exploited remotely, and the exploit has been publicly disclosed. Although the vendor was contacted early regarding this disclosure, there has been no response. The CVSS v4.0 score for this vulnerability is 2.1, classified as low severity.
Risk to organizations includes the potential for unauthorized access to user data, which could lead to data integrity issues. Although the CVSS score is low, the lack of vendor response and the public nature of the exploit warrant immediate attention. Organizations using affected versions should prioritize patching to mitigate the risk.
The urgency for defenders is moderate, as organizations should address this vulnerability in their priority patch cycle. Given the low complexity of the attack and the low privileges required, it is essential to assess the security posture and apply necessary updates as soon as possible.
In summary, organizations leveraging youlaitech youlai-boot should be aware of this vulnerability, understand its impacts, and take necessary actions to mitigate any potential risks.
Vulnerability Details
A security vulnerability has been detected in youlaitech youlai-boot up to version 2.21.1. This affects the function getUserList of the file src/main/java/com/youlai/boot/system/controller/UserController.java of the component Users Endpoint. Such manipulation of the argument order leads to SQL injection. The attack may be launched remotely. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
Technical Analysis
The root cause of this vulnerability stems from improper validation of input parameters in the getUserList function. Attackers may leverage this vulnerability to execute arbitrary SQL queries against the database, which can compromise confidentiality, integrity, and availability of data.
The attack vector for this vulnerability is network-based, allowing attackers to exploit it without physical access to the system. The attack complexity is low, with minimal privileges required for exploitation. User interaction is not required, making it easier for attackers to launch attacks remotely.
The confidentiality, integrity, and availability impact is assessed to be low, indicating that while the risks are present, they may not lead to widespread catastrophic effects. However, the potential for data leaks or unauthorized data manipulation necessitates attention.
Risk & Impact Analysis
Real-world deployment risk is primarily associated with the potential for unauthorized access to sensitive user data, which may be exploited by attackers. This matters significantly to organizations as it could lead to compliance issues and loss of customer trust.
The blast radius potential is moderate, as attackers exploiting this vulnerability could gain access to user data and potentially escalate their access within the system. Organizations should assess their exposure and ensure proper access controls are in place.
Urgency assessment based on CVSS indicates that while the risk is not classified as critical, organizations should address this vulnerability in their priority patch cycle to prevent exploitation.
