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

CVE-2026-23778 is a command injection vulnerability (CWE-77) affecting Dell PowerProtect Data Domain systems running Data Domain Operating System (DD OS). The vulnerability impacts Feature Release versions 7.7.1.0 through 8.5, LTS2025 release versions 8.3.1.0 through 8.3.1.20, and LTS2024 release versions 7.13.1.0 through 7.13.1.50. It carries a CVSS v3.1 base score of 7.2 (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to its potential for significant impact.

A high-privileged attacker with remote network access can exploit this vulnerability to execute arbitrary commands and escalate privileges to root-level access on the affected system. Exploitation requires high privileges (PR:H) but low attack complexity (AC:L), no user interaction (UI:N), and is feasible over the network (AV:N), with high impacts across confidentiality, integrity, and availability (C:H/I:H/A:H) while maintaining unchanged scope (S:U).

Dell has addressed this issue in security advisory DSA-2026-060, detailed at https://www.dell.com/support/kbdoc/en-us/000450699/dsa-2026-060-security-update-for-dell-powerprotect-data-domain-multiple-vulnerabilities, which provides security updates for multiple vulnerabilities in PowerProtect Data Domain, including recommended patches and mitigation guidance.

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation can discover command-construction flaws before deployment.

SI-10 Information Input Validation good match

Input validation directly stops construction of commands from untrusted data containing special elements.

SA-8 Security and Privacy Engineering Principles partial match

Secure engineering principles include proper neutralization and safe command construction practices.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require input validation and neutralization that prevent command injection.

DE.CM-09 partial match
prevents

Runtime monitoring of software and data can detect anomalous command execution resulting from injection.

ID.RA-01 partial match
prevents

Identifying recorded vulnerabilities enables remediation of command-injection flaws before exploitation.

A.8.28 Secure coding mostly match
prevents

Secure coding standards require proper escaping and parameterization of commands, directly eliminating CWE-77.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing in development catches command-injection vulnerabilities before release.

A.8.25 Secure development life cycle partial match
prevents

Secure development life cycle mandates input validation and command construction practices that directly prevent command injection.

A.8.26 Application security requirements partial match
prevents

Application security requirements explicitly call for controls against injection flaws including command injection.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure architecture principles reduce the attack surface but do not prescribe the specific neutralization techniques needed.

A.8.31 Separation of development, test and production environments none match
none

Environment separation limits the blast radius of an exploited command injection but does not prevent the flaw itself.
