CVE-2020-5370 — Dell EMC OpenManage Enterprise (OME) versions prior to 3.4 contain an arbitrary file overwrite vulnerability
High
CVSS 7.9
Dell EMC OpenManage Enterprise (OME) versions prior to 3.4 contain an arbitrary file overwrite vulnerability. A remote authenticated malicious user with high privileges could potentially exploit this vulnerability to overwrite arbitrary files via directory traversal sequences using a crafted tar file to inject malicious RPMs which may cause a denial of service or perform unauthorized actions.

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.
