CVE-2026-37071: Arbitrary File Rename Leading to Privilege Escalation in Actions::renameFile() function in Veno File Manage...

Arbitrary File Rename Leading to Privilege Escalation in Actions::renameFile() function in Veno File Manager Project 4.4.9 allows an authenticated attacker with 'reanme' permission to take over the super administrator account via a specially crafted POST request to the affected endpoint renaming the application configuration file and triggering a rebuild of configuration and resetting super administrator credentials to default values.

Security readout for executives and security teams

Plain-English summary

Veno File Manager Project 4.4.9 reportedly lets a user with file-renaming permission replace or move the application configuration file. Rebuilding the configuration can reset the super-administrator credentials to defaults, enabling account takeover and potentially complete compromise of the file-management service and its data.

Executive priority

Treat confirmed 4.4.9 deployments as an immediate remediation priority, especially when internet-facing. The reported outcome is super-administrator takeover with potentially complete service compromise. Because no patch is identified in the supplied evidence, reduce exposure and privileges while obtaining authoritative project guidance.

Technical view

The flaw is reported in Actions::renameFile() and classified as CWE-269. A crafted POST request can rename the configuration file, trigger configuration regeneration, and reset privileged credentials. The narrative requires an authenticated account with rename permission, although the supplied CVSS 3.1 vector states PR:N; this inconsistency needs vendor or CVE clarification.

Likely exposure

Likely exposure is limited to Veno File Manager Project 4.4.9 deployments where the affected endpoint is reachable and file-renaming capability is enabled. The supplied structured affected-product data is incomplete, so other affected versions cannot be confirmed. Internet-accessible deployments warrant immediate review.

Exploitation context

The supplied sources describe a network-reachable, low-complexity path with severe confidentiality, integrity, and availability impact. However, the bundle states the CVE is not in KEV and provides no evidence of active exploitation. Public technical material exists on GitHub, increasing the importance of prompt defensive review.

Researcher notes

The record contains a material prerequisite conflict: its description requires authentication plus rename permission, while CVSS reports PR:N. The affected array also lists vendor, product, and versions as n/a despite the title identifying Veno File Manager Project 4.4.9. Validate scope and scoring before broad conclusions. No active-exploitation claim is supported.

Mitigation direction

  • Check current vendor or project guidance for a fixed release or official workaround.
  • Restrict external access to Veno File Manager until remediation is confirmed.
  • Remove rename permission from nonessential accounts and apply least privilege.
  • Protect configuration files from application-level renaming where operationally feasible.
  • Rotate administrator credentials after confirming configuration integrity.

Validation and detection

  • Inventory Veno File Manager deployments and verify their exact versions.
  • Confirm whether Actions::renameFile() is reachable from untrusted networks.
  • Review accounts and roles holding rename permission.
  • Check configuration-file history, timestamps, and backups for unexpected renames or regeneration.
  • Verify super-administrator credentials were not reset to default values.
  • Review relevant POST requests and authentication logs for suspicious rename activity.
