CVE-2023-26101
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 · uneditedIn Progress Flowmon Packet Investigator before 12.1.0, a Flowmon user with access to Flowmon Packet Investigator could leverage a path-traversal vulnerability to retrieve files on the Flowmon appliance's local filesystem.
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 confidenceFlowmon Packet Investigator before version 12.1.0 contains a path traversal vulnerability that allows authenticated users with access to Packet Investigator to escape the intended directory boundaries and read arbitrary files from the Flowmon appliance's local filesystem.

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 Flowmon Packet Investigator versionLocate the installed version of Flowmon Packet Investigator via the web interface (typically in Help > About or Administration > System Information) or check the version file on the appliance filesystemAffected if version is below 12.1.0 (e.g., 12.0.x, 11.x, or earlier)
-
Verify Packet Investigator module is enabledCheck if the Packet Investigator feature is active and accessible in the Flowmon interface or via configuration filesAffected if Packet Investigator module is installed and enabled for use
-
Confirm user access to Packet InvestigatorReview user accounts and roles that have been granted access to the Packet Investigator functionality in the Flowmon authentication settingsAffected if any authenticated user accounts exist with Packet Investigator access permissions
-
Check for suspicious file access patternsReview Packet Investigator logs and audit trails for anomalous file retrieval requests that may indicate path traversal exploitationAffected if logs show file access requests outside expected directories (e.g., /etc/passwd, system configuration files)
You are affected if Flowmon Packet Investigator is installed at a version lower than 12.1.0 and the Packet Investigator feature is enabled for any authenticated users in your environment.
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 · scoped12.1.0
Upgrade Flowmon Packet Investigator to version 12.1.0 or later to obtain the vendor patch. If immediate upgrade is not feasible, restrict Packet Investigator access to trusted users only and monitor for anomalous file access patterns.
12.1.0 or later
- Identify the current version of Flowmon Packet Investigator installed on the appliance
- Review the Flowmon upgrade documentation at support.kemptechnologies.com or www.flowmon.com for upgrade procedures
- Plan and schedule the upgrade during a maintenance window
- Back up current configuration and any critical data
- Upgrade Flowmon Packet Investigator to version 12.1.0 or later
- Verify the upgrade was successful by checking the new version number
- Confirm the path traversal vulnerability is no longer exploitable
