CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:LSummary
CVE-2026-28265 is a medium-severity Path Traversal: '.../...//' (CWE-35) vulnerability in Dell Powerstoreos. Its CVSS base score is 4.4 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 2th 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-2026-28265 is a Path Traversal vulnerability (CWE-22 and CWE-35) in the Service user component of Dell PowerStore. Published on 2026-04-01, it carries a CVSS v3.1 base score of 4.4 (AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:L), indicating a medium severity issue with low complexity and privileges required but no confidentiality impact.
A low-privileged attacker with local access to PowerStore can exploit this vulnerability to modify arbitrary system files. Successful exploitation could compromise system integrity and availability, though it requires physical or local network proximity and does not enable remote code execution or privilege escalation beyond the attacker's initial access level.
Dell's security advisory DSA-2026-157 details a security update for PowerStore addressing this and multiple other vulnerabilities. Practitioners should consult the advisory at https://www.dell.com/support/kbdoc/en-us/000444169/dsa-2026-157-dell-powerstore-t-security-update-for-multiple-vulnerabilities for patch deployment instructions and affected versions.

Mitigating Controls (NIST 800-53 r5) AI
Enforces the intended directory access authorizations that path traversal would otherwise bypass.
Input validation directly neutralizes path sequences so the traversal cannot be introduced or exploited.
Enforces information flow rules that stop unauthorized directory escapes via crafted paths.
Least privilege reduces the impact of any successful traversal by limiting accessible resources.
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.
Secure SDLC practices directly require input validation and path sanitization that neutralize traversal sequences.
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 can detect path-traversal flaws before release.
Secure SDLC mandates input validation and path-handling controls that directly mitigate path traversal.
Application security requirements include rules for safe file-path construction and canonicalization.
Secure architecture principles require proper directory restrictions and input sanitization to prevent traversal.
Secure coding standards explicitly forbid unsafe path concatenation and mandate canonicalization routines.
Information access restriction limits file reachability but does not address the input-validation flaw itself.
