Vulnerability AssessmentAI

Exploitation Exploitation requires an authenticated user account with at least basic login credentials-the vulnerability cannot be exploited by unauthenticated remote attackers. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The risk profile presents a moderate but concrete threat requiring immediate attention. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An authenticated regular user logs into a KodExplorer instance with standard file management permissions. The attacker crafts a malicious HTTP request to the roleGroupAction function, manipulating the group_role parameter to assign themselves to an administrative role group. …
Remediation Immediate action: Upgrade KodExplorer to a version newer than 4.52 if such a version has been released post-disclosure (verify directly from Kodcloud's official repository, as no patched version is confirmed in provided data). … Detailed patch versions, workarounds, and compensating controls in full report.
