Release Highlight - Large Differential Feed Update Notification
Summary Due to integration of new binaries into the plugin feed, there will be a larger than normal differential plugin feed update. Potential Impacts: The addition of the binaries is expected to add approximately 37MB of new content to the plugin feed. The impact is expected to be minimal for Nessus customers. SC customers will see the biggest impact of approximately 230MB due to how the differential feed updates are built. The differential update does not apply to Nessus agents as the binaries were not added there. For Tenable Security Center customers, you can configure the plugins to update on a schedule or switch to manual updates for an optimal time window. Target Release Date March 4, 2026
Ruby Gem Enumeration Detection Updates
Summary Tenable has updated the Ruby gem enumeration plugins to reduce false positives and to better identify vulnerabilities when multiple packages are present on the scan target. Change Before this update, the Ruby gem enumeration plugins did not attempt to associate detected packages with an RPM or DEB package managed by the Linux distribution. This would cause some packages to report vulnerabilities both based on a Linux distribution vendor’s advisory and a CVE advisory from the Ruby gem maintainer. Some gems that are symbolically linked across the filesystem could be detected multiple times. After this update, these issues have been addressed. Vulnerable Ruby gems on Linux assets will be assessed to determine if they are managed by a Linux distribution’s package manager, and if so, will be marked as “Managed” and will not report a vulnerability, unless the [Override normal Accuracy] setting to Show potential false alarms setting is enabled for the scan. Gems that are symbolically linked will be followed to the source file; duplicate detections will be eliminated. The gem enumeration plugins will no longer report the list of detected gems in plugin output; rather, they will use only internal storage mechanisms to record the detected gems, so that Ruby vulnerability plugins can continue to use that data for version checks. Some issues were identified in the Ruby gem enumeration plugins that could have prevented some gems from being detected when the scan config was set to perform thorough checks. Those issues were corrected in this update. Impact Most customers will notice a reduction in the volume of Ruby gem vulnerabilities reported due to removal of duplicate findings. Some may notice a change in detected vulnerabilities due to the updates to thorough mode scanning. Detection plugins 240646 - Ruby Gem Modules Installed (macOS) 207584 - Ruby Gem Modules Installed (Linux) 207585 - Ruby Gem Modules Installed (Windows) Target Release Date March 2, 2026

Improvement to Printer OS Fingerprinting
Summary Scanned printers will now have an OS artefact surfaced in their scan host metadata if the target has been identified as a printer when the “Scan Network Printers” policy option is disabled. This change will not cause any additional asset licenses to be consumed within Tenable VM or Tenable Security Center. Background Printers are notoriously unstable scan targets. Oftentimes, they can behave erratically when scanned, so some users prefer to avoid scanning them altogether. At present, there is a switch in the scan policies to prevent further scanning of a host when it's identified as a printer. To enable this setting, go to Settings -> Host Discovery -> Fragile devices - Scan Network Printers (Currently, this is a checkbox setting, default value “off”). With that said, how can the scanner know the target is a printer if it cannot be scanned? In reality, the scanner still performs very basic fingerprinting (usually via SNMP) in order to gather enough information to make an educated guess at the device type. When the scan target is thought to be a printer, it essentially gets marked as “Host/dead" in the scan KB. When this happens, the scanner will not perform any further active scanning. Changes With this update, the fingerprint used to identify the printer as such, will now be stored in the scan Knowledge Base (KB) so it can be processed by os_fingerprint2.nasl ("Post-scan OS Identification", plugin ID 83349) and surfaced as metadata in the scan result. The relevant policy setting located at Settings -> Host Discovery -> Fragile devices -> Scan Network Printers, now has two options when enabled: Surface Printer OS only : The printer will be marked as dead and only the OS information gathered from fingerprinting will be surfaced (default option when setting is not enabled) Full Network Scan : The printer will not be marked as dead and a full scan will be performed, as if this were any other device. Impact Users can now see the OS information for their printer devices that would have otherwise gone unreported if the scan is not configured to “Scan Network Printers”. As plugin ID 83349 generates no plugin output, only an “operating-system” tag will be added to the scan result (and stored in an exported .nessus file). This information will be visible only the in “Host/Asset Details” section of the Tenable product UI, i.e: Tenable Nessus: Scans -> [Folder] -> [Individual Scan Result] - > Host Details -> OS (sidebar) Tenable Vulnerability Management: Explore -> Assets -> [Asset] -> Details -> Operating System Scans -> Vulnerability Management Scans -> [Individual Scan Result] -> Scan Details -> Asset Details -> Operating System Tenable Security Center: Analysis -> IP Summary -> [IP address] -> System Information -> OS Scans -> Scan Results -> [Individual Scan Result] -> IP Summary -> [IP address] -> System Information -> OS Note, we expect this information to surface mainly in individual scan results. It would only be present in cumulative asset details if a licensed asset already exists for the target in question. This update will not cause additional assets to be created or consume any additional licenses. Affected Plugins 83349 - os_fingerprint2.nasl 11933 - dont_scan_printers.nasl 22481 - dont_scan_settings.nasl Targeted Release Date Wednesday, March 4, 2026
Windows Patch Management Remediation Guidance
SUMMARY Tenable Research is making changes to Windows-based patch management integrations that affect vulnerability remediation. This announcement only applies to customers who are using the WSUS and SCCM patch management credentials. Vulnerabilities identified by WSUS and SCCM integrations will now be identified as “local checks”, which will cause them to now affect vulnerability remediation, also known as vulnerability mitigation. CHANGE Prior to this change, vulnerabilities identified by these scans could not be remediated except by a Host credentialed scan - in other words, a Windows (SMB) credential. After this change, vulnerabilities identified by these Windows patch management scans may be remediated with a subsequent Windows patch management scan. Windows patch management credentials will identify only a subset of the vulnerabilities that a Host credentialed scan will. Therefore, a scenario could arise in which a patch management scan incorrectly remediates vulnerabilities previously identified by a Host credentialed scan. To prevent incorrectly remediating vulnerabilities, Tenable advises customers using a combination of patch management and Host credentials to combine them in a single scan, rather than running them in separate scans. IMPACT Customers who are not using patch management credentials are not affected by this change. Customers using patch management credentials but not Host credentials do not need to take any action, but will now see vulnerabilities identified by Windows and SCCM integrations being remediated. The guidance to combine credentials in a single scan applies to customers who are using Windows-based patch management credentials in combination with Windows Host (SMB) credentials.

Research Release Highlight - SSH Session Reuse
Summary Nessus scan will support an opt-in feature to reuse SSH sessions during a scan where possible when running Nessus versions 10.9.0 and greater. This update was made in response to numerous customer requests for reducing the number of new SSH connections established during remote network scans and the associated increase in network traffic. Change A new scan configuration template option will be available for customers to actively enable the [Reuse SSH connections] configuration in their scan policies in Advanced Settings under Advanced Performance Options. Customers can return to the classic SSH connection functionality by changing [Reuse SSH connections] to the default “off” setting in their scan policies. Customers must be running a version of Nessus 10.9.0 or greater that supports this feature and have a Plugin Feed that displays the scan configuration policy user interface and NASL plugin set with the SSH session reuse functionality. Impact Customers should see a significant decrease in the total number of SSH sessions established during a Nessus scan as well as a reduction in load on Enterprise authorization, access, and accounting (AAA) tooling such as RADIUS servers and other connection management services. There should be no difference in scan results between scans that leverage SSH Session Reuse and scans that do not. If customers experience any such issues, the feature can easily be toggled off to return SSH connections during scans to the classic connection functionality.

Summary Tenable is announcing changes to our documentation for the Cisco Meraki API integration. Customers using a “unique” host in the “Cisco Meraki Host” field of the credential should use “api.meraki.com”, or a region-specific instead if applicable. Please refer to the documentation for full guidance. Tenable and Cisco Meraki Integration Guide Impact Customers using the Cisco Meraki API integration are encouraged to check their configurations and update them accordingly. This change in guidance addresses cases where some customers were experiencing HTTP 308 redirects, resulting in integration failures. This is also closely related to cases where customers were experiencing HTTP 403 errors, which has been addressed by changes in the Cisco Meraki API Web Application Firewall (WAF).
