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

CVE-2026-23775 is an insertion of sensitive information into log file vulnerability (CWE-532) affecting Dell PowerProtect Data Domain appliances running Data Domain Operating System (DD OS) Feature Release versions 8.0 through 8.5 and LTS2025 release versions 8.3.1.0 through 8.3.1.10. The issue enables the logging of sensitive credentials, with a CVSS v3.1 base score of 7.6 (AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:H/A:H). This vulnerability is present only on systems with retention lock enabled.

A low-privileged attacker with remote access could exploit this vulnerability by triggering conditions that insert sensitive information into log files, potentially leading to credential exposures. Exploitation requires user interaction and is further constrained: authentication attempts using the compromised credentials must be authorized by a high-privileged DD user.

Dell Security Advisory DSA-2026-060 addresses this and other vulnerabilities in PowerProtect Data Domain, providing a security update for affected versions. Security practitioners should consult the advisory at https://www.dell.com/support/kbdoc/en-us/000450699/dsa-2026-060-security-update-for-dell-powerprotect-data-domain-multiple-vulnerabilities for patch details and mitigation guidance.

Mitigating Controls

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-532

Procedures mandate excluding sensitive data from logs to prevent unauthorized exposure via audit records.

addresses: CWE-532

Identifies insertion of sensitive data into logs, allowing detection of unauthorized disclosure.

addresses: CWE-532

Cross-organizational coordination enables agreement on what data to include in audit logs, directly reducing insertion of sensitive information.

addresses: CWE-532

Identifying logging as a data action allows prevention of sensitive information being inserted into log files.

addresses: CWE-532

The process of identifying and eradicating spilled information applies directly to sensitive data inserted into log files.

addresses: CWE-532

Specific processing rules for sensitive PII categories commonly include restrictions on logging, making insertion of such data into log files less likely.

addresses: CWE-532

PIAs detect planned or existing logging of PII and require removal or protection, preventing insertion of sensitive information into logs.

addresses: CWE-532

Limits insertion of sensitive operational details into logs by treating such data as key information requiring protection.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly prohibit writing sensitive data to logs; eliminating the weakness satisfies only one narrow slice of the control.

PR.PS-04 partial match
prevents

Log generation configuration can and should exclude sensitive data, but the control statement focuses on availability rather than content filtering.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.15 Logging mostly match
prevents

Requiring de-identification and privacy controls before logs leave the organization reduces the chance that sensitive data inadvertently captured in logs becomes exposed to external parties.

mitigates

By defining what records must be kept, where, and for how long, the control discourages the inadvertent inclusion of sensitive information in logs or other externally accessible files that fall outside the formal record system.

mitigates

Mandating deletion of temporary files and logs that may contain sensitive information prevents those artifacts from remaining accessible after the data is no longer needed.

A.8.11 Data masking partial match
mitigates

When log entries are produced from masked data sets, the control prevents the inadvertent insertion of sensitive values into externally accessible log files.

mitigates

DLP inspection of logs and file transfers can detect and block the inadvertent placement of sensitive tokens or credentials into externally accessible log files before they are written or transmitted.

prevents

Requiring restrictions on free-text fields and proper error-message handling stops developers from embedding or leaking sensitive data into logs or diagnostic output.
