CVE-2023-22649
Published: 16 October 2024
Summary
CVE-2023-22649 is a high-severity Insertion of Sensitive Information into Log File (CWE-532) vulnerability in Suse Rancher. Its CVSS base score is 8.4 (High).
Operationally, ranked in the top 2.3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
A vulnerability in Rancher allows sensitive data to be written into audit logs when the optional audit logging feature is enabled with AUDIT_LEVEL set to 1 or higher. The issue is tracked as CVE-2023-22649 and is classified under CWE-532, with a CVSS 4.0 score of 8.4 reflecting high confidentiality and integrity impact across network-accessible deployments.
An attacker who can access the generated audit logs can obtain the leaked sensitive information. The vulnerability requires privileged credentials and user interaction, limiting the set of actors who can trigger or observe the disclosure to those already holding administrative access within an affected Rancher environment.
The referenced SUSE Bugzilla entry and GitHub Security Advisory note that only deployments with audit logging explicitly turned on are impacted and provide no additional configuration changes or patches beyond disabling the feature or lowering the audit level. The associated EPSS score has remained flat at 0.4519 with no material increase since disclosure.

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.
Procedures mandate excluding sensitive data from logs to prevent unauthorized exposure via audit records.
Identifies insertion of sensitive data into logs, allowing detection of unauthorized disclosure.
Cross-organizational coordination enables agreement on what data to include in audit logs, directly reducing insertion of sensitive information.
Identifying logging as a data action allows prevention of sensitive information being inserted into log files.
The process of identifying and eradicating spilled information applies directly to sensitive data inserted into log files.
Specific processing rules for sensitive PII categories commonly include restrictions on logging, making insertion of such data into log files less likely.
PIAs detect planned or existing logging of PII and require removal or protection, preventing insertion of sensitive information into logs.
Limits insertion of sensitive operational details into logs by treating such data as key information requiring protection.
