CVE-2025-43937
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedDell PowerScale OneFS, versions prior to 9.12.0.0, contains an insertion of sensitive information into log file vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to the disclosure of certain user credentials. The attacker may be able to use the exposed credentials to access the vulnerable application with privileges of the compromised account.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceDell PowerScale OneFS prior to version 9.12.0.0 improperly logs sensitive user credentials, allowing a low-privileged local attacker to read log files and obtain credentials that can then be used to authenticate as compromised users.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check the installed PowerScale OneFS versionRun 'isi version' or 'isi get version' from the OneFS CLI to obtain the current firmware versionAffected if The installed version falls within the affected ranges: < 9.5.1.5, >= 9.6.0.0 and < 9.7.1.10, >= 9.8.0.0 and < 9.10.1.3, or >= 9.11.0.0 and < 9.12.0.0
-
Locate system log files that may contain credentialsNavigate to the OneFS log directory, typically /var/log/ or access logs via 'isi log' commands, and identify log files such as audit.log, auth.log, or application-specific logsAffected if Log files exist and are readable by non-privileged users on the system
-
Verify log file permissions allow low-privileged accessUse 'ls -la' or 'isi getacl' on log files in /var/log/ to inspect read permissions, checking if world-readable or group-readable by users outside the admin groupAffected if Log files have permissions that permit read access by non-admin, low-privileged local users
-
Search log files for exposed credentialsUse 'grep -i' or 'isi log' search functionality to look for patterns such as 'password', 'passwd', 'credential', 'secret', or API keys in plaintext within log filesAffected if Log files contain plaintext passwords, credentials, or sensitive authentication tokens
-
Check for recent unauthorized access using logged credentialsReview authentication logs for successful logins using accounts that may have been exposed in logs, looking for unusual source IPs or timingAffected if There are login records matching credentials that were previously logged in plaintext
A system is affected if it runs a PowerScale OneFS version prior to 9.12.0.0 and has log files with readable permissions that may contain improperly logged credentials.

dbcve · scoped9.5.1.59.7.1.109.10.1.3
Upgrade Dell PowerScale OneFS to version 9.12.0.0 or later. Additionally, review and secure log file permissions to limit access and ensure no sensitive data is written to logs.
9.12.0.0
- Identify current PowerScale OneFS version using 'isi version' or OneFS web UI
- Review Dell PowerScale OneFS 9.12.0.0 release notes for upgrade prerequisites and注意事项
- Create a backup of critical data and configuration
- Schedule maintenance window for the upgrade
- Follow Dell official upgrade procedure to upgrade to 9.12.0.0 or later
- After upgrade, verify the version with 'isi version'
- Confirm that user credentials are no longer being written to log files
