CVE-2025-59784
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 · unedited2N Access Commander version 3.4.1 and prior is vulnerable to log pollution. Certain parameters sent over API may be included in the logs without prior validation or sanitisation. This vulnerability can only be exploited after authenticating with administrator privileges.
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 confidence2N Access Commander versions 3.4.1 and prior contain a log pollution vulnerability where certain API parameters are written to application logs without validation or sanitization. An authenticated administrator can inject arbitrary content into logs through unsanitized API parameters, potentially enabling log injection attacks, log forging, or manipulation of log analysis systems.

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 installed 2N Access Commander versionAccess the administration interface or check system information to determine the currently installed version of 2N Access Commander. This is typically visible in the About section or system settings.Affected if The installed version is 3.4.1 or any version prior to 3.4.2
-
Verify administrator account existsCheck if there is at least one active administrator account configured in the 2N Access Commander system. Log into the administration interface and navigate to user management.Affected if An authenticated administrator account exists and can access the API interface
-
Confirm API logging is activeExamine the application logs directory for 2N Access Commander. Look for log files that record API requests and their parameters. Default locations may include /var/log/ or the application's data directory.Affected if API requests are being logged to disk and the log files contain parameter data from API calls
You are affected if you are running version 3.4.1 or prior and your system logs API parameters from authenticated administrator sessions to accessible log files.

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 · scoped3.4.2
Implement input validation and sanitization for all API parameters before they are written to logs. Upgrade to a patched version of 2N Access Commander if available. Additionally, ensure log consumers perform output encoding when parsing or displaying logged data.
Access Commander 3.4.2
- Verify current Access Commander version in use
- Download Access Commander version 3.4.2 from the official 2N website or trusted distribution channel
- Review upgrade documentation specific to Access Commander
- Perform upgrade following standard 2N upgrade procedures
- Verify successful upgrade to version 3.4.2 or later
- Confirm administrator access is properly secured post-upgrade
