CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:LSummary
CVE-2026-27101 is a medium-severity Path Traversal (CWE-22) vulnerability in Dell Secure Connect Gateway. Its CVSS base score is 4.7 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 31th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2026-27101 is an Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability, certified under CWE-22, affecting Dell Secure Connect Gateway (SCG) 5.0 Appliance and Application versions 5.28.00.xx through 5.32.00.xx. Published on April 1, 2026, it has a CVSS v3.1 base score of 4.7 (AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:L), indicating medium severity with network accessibility, low attack complexity, but requiring high privileges.
A high-privileged attacker within the management network can exploit this path traversal flaw to achieve remote code execution. The attacker leverages insufficient pathname restrictions to access restricted directories, potentially executing arbitrary code on the affected SCG appliance or application.
Dell advisory DSA-2026-020, detailed at https://www.dell.com/support/kbdoc/en-us/000438589/dsa-2026-020-security-update-for-dell-secure-connect-gateway-application-and-appliance-vulnerabilities, addresses this and related vulnerabilities with a security update for the SCG Application and Appliance.

Mitigating Controls (NIST 800-53 r5) AI
Enforces the intended directory access authorizations that path traversal would otherwise bypass.
Input validation directly neutralizes special path elements before pathname construction occurs.
Least privilege reduces the impact of any unauthorized file access obtained via traversal.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
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 defines and reviews access policies but does not address code-level pathname neutralization, so neither direction prevents CWE-22.

Security testing in development catches path traversal via static/dynamic analysis.
Secure SDLC mandates input validation and path sanitization that directly prevent path traversal.
Application security requirements include rules for safe file handling and canonicalization.
Secure architecture principles require least-privilege file access and directory isolation.
Secure coding standards explicitly forbid unsafe path construction and mandate safe APIs.
Information access restriction limits which files an application may read or write.
