CVE-2024-39865 — A vulnerability has been identified in SINEMA Remote Connect Server (All versions < V3.2 SP1)

High CVSS 8.8

A vulnerability has been identified in SINEMA Remote Connect Server (All versions < V3.2 SP1). The affected application allows users to upload encrypted backup files. As part of this backup, files can be restored without correctly checking the path of the restored file. This could allow an attacker with access to the backup encryption key to upload malicious files, that could potentially lead to remote code execution.

Matched remediation archetype

Path traversal, unsafe upload, and file handling

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace untrusted filenames, archive entries, URLs, and path segments into read, write, include, extraction, and upload operations.
  • Identify filesystem roots, mount permissions, symbolic-link behavior, archive handling, and whether uploaded content is web-accessible or executable.
  • Review canonicalization and containment checks across supported operating systems and storage backends.

Remediate safely

  • Generate server-side storage identifiers and resolve paths beneath a fixed root using filesystem-aware containment checks.
  • Reject absolute, parent-relative, alternate-separator, device, link, and archive entries that escape the intended root.
  • Store uploads outside executable or served paths, validate type and size, and use private atomic temporary files.
