DescriptionCVE.org

A security flaw has been discovered in kodcloud KodExplorer up to 4.52. Affected is the function initInstall of the file /app/controller/systemMember.class.php. Performing a manipulation of the argument path results in authorization bypass. The attack may be initiated remotely. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.

AnalysisAI

Remote authorization bypass in KodCloud KodExplorer up to version 4.52 allows high-privileged authenticated attackers to manipulate the path argument in the initInstall function (/app/controller/systemMember.class.php), resulting in integrity compromise. The exploit code is publicly available, and the vendor has not responded to early disclosure notifications, leaving deployed instances vulnerable without official remediation guidance.

Vulnerability AssessmentAI

Exploitation Exploitation requires the attacker to be an authenticated user with high privileges (PR:H) - specifically, an administrator or user with access to the systemMember controller. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The risk profile presents a notable discrepancy between the CVSS score and real-world exploitability. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An authenticated administrator with high-privilege credentials logs into KodExplorer and crafts a malicious HTTP request to the initInstall function, manipulating the path parameter to values outside the intended scope (e.g., traversal sequences or unvalidated identifiers). The application fails to re-validate authorization for the manipulated path, allowing the administrator to bypass intended access restrictions and modify system initialization settings, such as user account creation, permission configuration, or feature activation. …
Remediation No vendor-released patch has been identified at time of analysis, as KodCloud did not respond to early disclosure notifications. … Detailed patch versions, workarounds, and compensating controls in full report.

Threat intelligence, references, and detailed analysis are available after sign-in.
