CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:HSummary
CVE-2026-49813 is a medium-severity OS Command Injection (CWE-78) vulnerability in Dell Data Domain Operating System. Its CVSS base score is 6.7 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Unix Shell (T1059.004); ranked at the 37th 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-6 (Least Privilege) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Why these techniques?
OS command injection (CWE-78) on a Unix-based appliance directly enables arbitrary command execution via Unix Shell.

Control response
Mitigating Controls (NIST 800-53 r5) AI
Directly requires validation of inputs to block special characters used in OS command injection (CWE-78).
Limits privileges so a local attacker cannot reach the high-privileged context required to exploit the injection.
Restricts available OS commands and interpreters, reducing the attack surface for arbitrary command execution.

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.
PR.PS-06's SDLC practices directly require secure coding and input handling that blocks command-injection defects, yet the single broad outcome leaves many specific neutralization vectors and verification gaps unaddressed.
Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).

Security testing and code review target insecure use of operating-system command interfaces, catching command-injection flaws introduced during development.
