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 prevent embedding sensitive data in query strings as part of input-handling and data-flow design.

PR.DS-02 partial match
prevents

HTTPS encryption protects query strings in transit but does not address the root design flaw of placing sensitive data in URLs.

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.

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.

finds

Security testing can detect sensitive data leakage via query strings.

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 solutions can detect and block sensitive data in URLs.
