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, 2026Component Installs Require Paranoid Checks
Update - February 12, 2026 After considering customer feedback, we. have decided to re-evaluate these changes and come up with a better way of handling Component installs. Once the plan is finalised, the details will be shared here. Summary With this update, products that are deemed to be components of another application, will now require the scan to be run in paranoid mode to trigger generic vulnerability detection plugins. In this context, “generic vulnerability detection plugins” refers to plugins that cover advisories published by the component vendor (e.g., plugin ID 242325, SQLite < 3.50.2 Memory Corruption) rather than the operating system or “parent” application that distributes the component, either as a part of the operating system or a dependent tool of the parent application. Overview Tenable covers software that can be either installed as base level software, or be included as component software of a larger product installation. Base level software can be updated without any impact to the base product functionality. Component software is typically updated as part of the vendor update for the larger packaged product, and the individual components are not updatable. Non-paranoid scans will report base software vulnerabilities that are actionable. Paranoid scans will report on base software vulnerabilities as well component software vulnerabilities that are not actionable, but still package a potentially vulnerable version of the component. To enhance the accuracy of our vulnerability detection and provide users with greater control over scan results, we are implementing an update affecting how we flag vulnerabilities in software components. Our detection plugins for OpenSSL, Curl, LibCurl, Apache HTTPD, Apache Tomcat, SQLite, PHP, Python packages and Node.js modules can now identify when these packages are installed as components of another parent application (e.g., SQLite bundled with Trend Micro’s Deep Security Agent), rather than as standalone installs. Key Changes: Non-Paranoid Scans: Scans running in the default mode will no longer flag generic vulnerability detection plugins for these component installs. This is because vulnerabilities in components generally cannot be patched directly; users must wait for the parent application's vendor to issue an update. OS Vendor Advisories Unaffected: This change does not affect plugins for OS vendor security advisories that cover the same vulnerabilities (e.g., plugin ID 243452, RHEL 9 : sqlite (RHSA-2025:12522)). Paranoid Scans: For scans running in paranoid mode, generic vulnerability detection plugins will still trigger for component installs if the detected version is lower than the expected fixed version. Expected Impact: Customers running non-paranoid scans should anticipate seeing a reduction in potential vulnerability findings for OpenSSL, Curl, LibCurl, Apache HTTPD, Apache Tomcat, SQLite, PHP, Python packages and Node.js modules that are installed as components. Technical Details: The changes are entirely contained within two shared libraries, vcf.inc and vdf.inc, utilized by the affected plugins. This update impacts approximately 750 plugins specific to OpenSSL, Curl, LibCurl, Apache HTTPD, Apache Tomcat, and SQLite. Targeted Release Date: Friday, February 6, 2026
Compliance Windows Command Execution Enhancement
Summary The Windows Compliance Check plugin is implementing an updated library to run commands on Windows targets. The enhancements will include the following benefits. The plugin will improve on its handling of command timeouts. There were issues when long running commands would timeout on the scanner but leave temporary files on the target. This update will force long running checks to close when timing out and remove temporary files. The recently released improved resource management controls for Windows plugins on agents will now be extended to running audits. Potential Impacts: Tenable has gone to great lengths to ensure that the content that it publishes will operate and produce the same results that it always has. Customized audits may exhibit some changes due to the introduced job control of the command execution. These changes tend to be compliance checks that generate different results (failure instead of passing), or the actual values of the check have different text that would affect baseline scans. If custom content does exhibit these issues, strategies to work with the new library can be found in Compliance WMI Library Enhancement. Tenable Plugins 21156 - Windows Compliance Checks Target Release Date February 9, 2026Disable Red Hat repository correlations and strictly use package version checks
Summary With this update, users will now have the ability to disable the requirement to consider the enabled yum updated repositories before proceeding to package version checks to determine vulnerability status for Red Hat Local Security Checks plugins. This option can now be toggled on/off via the scan policy.To toggle this new feature in your scan policy, navigate to Settings > Advanced > Vulnerability Options and toggle "Disable RedHat repository correlations and strictly use package version checks" on/off as desired. Background To understand how Tenable's Red Hat Local Security Checks plugins currently work, please refer to the following document: How Red Hat Local Vulnerability Checks Use Repositories To Determine Scope. Expected Impact Users should potentially expect to see more Vulnerability findings in their scans when this option is enabled. This is expected because the plugins will no longer consider whether or not the target machine has the specified repository enabled to receive the fixed package(s). Instead, the plugins will only check that any version of the affected package is installed, and proceed straight to version comparison. Tenable's RPM package parsing libraries have extensive functionality to ensure package version checks are as accurate as possible, but due to the potential differences in epoch versions and package naming and versioning discrepancies between the different repositories, potential false positives are possible when this feature is enabled. Affected Plugins Red Hat Local Security Checks Targeted Release Date Thursday, February 5, 2026 Note, not all Red Hat Local Security Check plugins can avail of the this feature yet. Only plugins that have include("rpm2.inc") can use this new feature. There is work ongoing to bring all of these plugins up to date.

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. Impact Most customers will notice a reduction in the volume of Ruby gem vulnerabilities reported.
