A vulnerability was found in JeecgBoot up to 3.9.1. This vulnerability allows manipulation of the argument ruleClass in the FillRuleUtil component, resulting in improper authorization. The attack may be performed from remote, and the exploit has been made public. Organizations are advised to upgrade the affected component as the vendor has confirmed the issue and will provide a fix in the upcoming release.
The severity of this vulnerability is classified as low, with a CVSS score of 2.1. While the impact may be minimal, it exposes organizations to potential unauthorized access if not addressed. The existence of a public exploit underscores the need for vigilance. Organizations should prioritize patching this vulnerability to mitigate any possible exploitation.
The exploitability score is low, and the exploit has been confirmed as a proof of concept. Therefore, while immediate action may not be critical, organizations should address this vulnerability within their regular patch management cycles.
Organizations should prioritize patching immediately. This proactive measure will help safeguard systems against potential unauthorized access resulting from this vulnerability.
Vulnerability Details
A vulnerability was found in JeecgBoot up to 3.9.1. Affected by this vulnerability is an unknown functionality of the file /sys/fillRule/edit of the component FillRuleUtil Component. The manipulation of the argument ruleClass results in improper authorization. The attack may be performed from remote. The exploit has been made public and could be used. You should upgrade the affected component. The vendor confirmed the issue and will provide a fix in the upcoming release.
Technical Analysis
The root cause of this vulnerability stems from improper authorization management in the FillRuleUtil component. Attackers may exploit this flaw over the network with low complexity and low privileges required. As such, user interaction is not necessary for an attack to be successful. The impacts on confidentiality, integrity, and availability are all assessed as low.
Risk & Impact Analysis
Risk to organizations includes potential unauthorized access to sensitive data or functions due to improper authorization. Given the low CVSS score, the immediate threat level is low; however, organizations should not overlook the risk posed by unpatched vulnerabilities. The potential blast radius could be limited, but proactive risk management is recommended.
