CVE-2024-38909: Studio 42 elFinder 2.1.64 is vulnerable to Incorrect Access Control.
Studio 42 elFinder 2.1.64 is vulnerable to Incorrect Access Control. Copying files with an unauthorized extension between server directories allows an arbitrary attacker to expose secrets, perform RCE, etc.
Security readout for executives and security teams
Plain-English summary
CVE-2024-38909 is a critical access-control flaw reported in Studio 42 elFinder 2.1.64. The source says an unauthenticated attacker may copy files with unauthorized extensions between server directories, potentially exposing secrets or enabling remote code execution. Confirm exposure before assuming impact because the CVE record lists incomplete product metadata.
Executive priority
Prioritize within the critical vulnerability queue for any exposed elFinder deployment. The business concern is not just file disclosure; the source states possible remote code execution. Because patch data is absent in the bundle, assign ownership to confirm vendor guidance and containment immediately.
Technical view
The CVE describes CWE-284 incorrect access control in elFinder 2.1.64 during server-side file copy handling. The CVSS 3.1 vector is network-reachable, low complexity, no privileges, no user interaction, with high confidentiality, integrity, and availability impact. No vendor patch, affected CPE, or configuration-specific remediation is provided in the supplied sources.
Likely exposure
Risk is highest for internet-facing or unauthenticated elFinder 2.1.64 deployments, especially where file manager directories can contain secrets or executable server-side files. Exposure cannot be fully scoped from the bundle because affected vendor and CPE fields are marked n/a.
Exploitation context
The bundle does not show CISA KEV listing or cited evidence of active exploitation. A public GitHub reference exists, but this analysis does not rely on or provide exploitation details. Treat the issue as high urgency due to unauthenticated network attack surface and critical CVSS impact.
Researcher notes
Evidence quality is mixed: the CVE description and CVSS indicate severe unauthenticated impact, but affected product metadata is incomplete and no official fix is named. Avoid over-claiming active exploitation. Focus validation on real elFinder 2.1.64 deployment paths, authentication boundaries, file-copy behavior, and executable-directory controls.
Mitigation direction
Identify any deployed elFinder 2.1.64 instances and their access paths.
Check upstream Studio 42 elFinder guidance for fixed versions or official mitigations.
Restrict or disable public access to elFinder until guidance is applied.
Enforce authentication and least-privilege file-system access for file manager endpoints.
Prevent uploaded or copied files from executing in served directories.
Monitor for unexpected file copies, extension changes, and secret-file access.
Validation and detection
Inventory application dependencies and bundled assets for elFinder 2.1.64.
Confirm whether elFinder routes are reachable without authentication.
Review configuration for allowed extensions, connector roots, and writable directories.
Check server logs for suspicious cross-directory copy operations.
Verify web server rules block script execution from upload directories.
Document any compensating controls and remaining exposure gaps.

CWE-284: Authorization and privilege behavior lookup
Authorization weaknesses can support privilege escalation and valid-account review, depending on exploit path. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
The CVE wording references code or command execution, so execution technique review may help defensive triage. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.
