CVE-2023-3252
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 · uneditedAn arbitrary file write vulnerability exists where an authenticated, remote attacker with administrator privileges could alter logging variables to overwrite arbitrary files on the remote host with log data, which could lead to a denial of service condition.
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 · moderate confidenceThis is an authenticated arbitrary file write vulnerability in the product's logging functionality. An attacker with administrator privileges can manipulate logging variables (likely through path traversal or log file path injection) to write log data to arbitrary files on the filesystem, potentially overwriting critical system files and causing denial of service.

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.
-
Identify the installed Nessus versionAccess the Nessus web interface (typically port 8834) or run 'nessusd -v' from the command line to retrieve the exact version numberAffected if The version displayed is earlier than 10.6.0 (for example, 10.5.0, 10.4.x, or earlier)
-
Confirm administrator account access existsCheck for any active administrator-level user accounts in Nessus by accessing Settings > Users in the web interface or querying the users databaseAffected if At least one administrator account is enabled and accessible (the attacker requires administrator privileges to exploit this flaw)
-
Verify the logging configuration interface is accessibleNavigate to Settings > Logging (or similar logging configuration section) in the Nessus web interface to see if logging path parameters can be configuredAffected if The logging configuration panel allows modification of log file paths or log directory settings
-
Inspect logging path settings for path traversal indicatorsReview the current logging configuration for any log file path entries containing '..' sequences or absolute paths pointing outside the default Nessus directoryAffected if The configured log path contains path traversal sequences (such as ../) or points to system directories outside the default Nessus installation folder
Your environment is affected if Nessus version is below 10.6.0 AND an administrator account can access the logging configuration interface to manipulate log file paths.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped10.6.0
Restrict administrator privileges to trusted personnel, implement strict input validation on logging path parameters to prevent path traversal, and apply vendor patches when available.
Nessus 10.6.0 or later
- 1. Backup your current Nessus installation and configuration before upgrading.
- 2. Download Nessus version 10.6.0 or later from the Tenable downloads page.
- 3. Stop the Nessus service on the host system.
- 4. Install the Nessus upgrade package for your operating system.
- 5. After installation, verify the installed version is 10.6.0 or higher using 'nessuscli --version' or the web interface.
- 6. Start the Nessus service.
- 7. Verify all plugins and configurations are working correctly after the upgrade.
