Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

Directory Traversal vulnerability CVE-2023-39026 affects FileMage Gateway Windows deployments version 1.10.8 and earlier. The flaw, assigned CWE-22 and a CVSS 3.1 score of 7.5, resides in the /mgmt/ component and permits remote retrieval of arbitrary files without authentication or user interaction.

An unauthenticated attacker can supply a crafted request to the /mgmt/ endpoint and read sensitive information stored on the host filesystem. Exploitation requires only network access and succeeds against any unpatched instance exposed to the internet.

Public proof-of-concept code demonstrating local file inclusion has been posted to PacketStorm, accompanied by a detailed technical write-up. The vendor change log at filemage.io documents subsequent updates, while the EPSS score stands at 0.8395.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

SI-10 Information Input Validation
addresses: CWE-22

Validates pathnames and filenames to prevent traversal outside intended directories.

PR.PS-02 partial match
blocks

Patching/maintenance can remediate known path-traversal flaws in deployed software (partial prevention of exploitability) but does nothing to stop the coding defect from being introduced in the first place.

PR.AA-05 none match
blocks

PR.AA-05 defines and reviews access policies but does not address code-level pathname neutralization, so neither direction prevents CWE-22.
