Summary

CVE-2026-59909 is a high-severity Path Traversal: '.../...//' (CWE-35) vulnerability in Dell Objectscale. Its CVSS base score is 7.1 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Data from Local System (T1005); 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 SI-10 (Information Input Validation) and AC-3 (Access Enforcement) — see the control section below for these in your framework.

T1005 Data from Local System Collection
Adversaries may search local system sources, such as file systems, configuration files, local databases, virtual machine files, or process memory, to find files of interest and sensitive data prior to Exfiltration.
T1083 File and Directory Discovery Discovery
Adversaries may enumerate files and directories or may search in specific locations of a host or network share for certain information within a file system.
T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Input validation directly neutralizes path sequences so the traversal cannot be introduced or exploited.

Enforces access authorizations on the resulting pathname, blocking traversal attempts from succeeding.

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.

prevents

Secure SDLC practices directly require input validation and path sanitization that neutralize traversal sequences.

finds

Security testing in development can detect path-traversal flaws before release.

prevents

Secure SDLC mandates input validation and path-handling controls that directly mitigate path traversal.

prevents

Application security requirements include rules for safe file-path construction and canonicalization.

prevents

Secure architecture principles require proper directory restrictions and input sanitization to prevent traversal.

prevents

Secure coding standards explicitly forbid unsafe path concatenation and mandate canonicalization routines.

mitigates

Information access restriction limits file reachability but does not address the input-validation flaw itself.
