CVE-2023-3329 — SpiderControl SCADA Webserver versions 2.08 and prior are vulnerable to path traversal
Medium
CVSS 6.5
SpiderControl SCADA Webserver versions 2.08 and prior are vulnerable to path traversal. An attacker with administrative privileges could overwrite files on the webserver using the HMI's upload file feature. This could create size zero files anywhere on the webserver, potentially overwriting system files and creating a denial-of-service condition.

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.
