DescriptionCVE.org

A security vulnerability has been detected in xianrendzw EasyReport up to 2.0.17.0522_Beta. The affected element is the function DataSourceController.add of the file DataSourceController.java of the component QueryerFactory. Such manipulation of the argument queryerClass leads to permission issues. The attack can be launched remotely. The exploit has been disclosed publicly and may be used. The project was informed of the problem early through an issue report but has not responded yet.

AnalysisAI

Permission bypass in xianrendzw EasyReport up to version 2.0.17.0522_Beta allows authenticated low-privilege remote attackers to manipulate the queryerClass argument in the DataSourceController.add method within the QueryerFactory component, resulting in unauthorized access to or modification of data source configurations. A public proof-of-concept exploit has been disclosed via GitHub issue #83, and the project maintainer has not yet acknowledged or remediated the finding. …

Vulnerability AssessmentAI

Exploitation Exploitation requires a valid low-privilege authenticated session on an EasyReport instance - the CVSS 4.0 vector metric PR:L explicitly confirms that some form of authentication is mandatory and unauthenticated exploitation is not possible. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 score of 2.1 reflects a genuinely low-severity issue: the attacker must hold at minimum low-privilege credentials (PR:L), and all CIA triad impacts are rated Low (VC:L/VI:L/VA:L) with no scope change affecting subsequent systems (SC:N/SI:N/SA:N). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker with a valid low-privilege EasyReport account sends a crafted HTTP POST to the DataSourceController.add endpoint, supplying a manipulated queryerClass argument that the QueryerFactory component fails to validate against a permitted type allowlist. Exploiting the permission gap, the attacker reads or modifies data source configurations beyond their authorized scope. …
Remediation No vendor-released patch has been identified at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report.
