The Vulners team has released nmap-vulners 2.0

The Vulners team has released nmap-vulners 2.0. This plugin (an NSE script) turns the popular Nmap port scanner into a black-box vulnerability scanner. Simply run $ nmap -sV --script vulners <target> to get a prioritized report on vulnerabilities and exploits. And all of this is available for free with no limitations. 🆓😉

How exactly does this plugin work?

To find vulnerabilities, the software is identified first:

🔹 The service's CPE identifier may be provided by Nmap itself (using the -sV option).

🔹 If Nmap fails to identify the service, the plugin attempts to determine the CPE identifier from the raw banner using rules for FTP, SMTP, SSH, MySQL, DNS, NTP, LDAP, and other services. Starting with version 2.0, the fingerprint catalog is updated weekly based on Recog, Wappalyzer, WhatWeb, FingerprintHub, and nuclei-templates. The latest catalog is automatically fetched when the plugin runs.

🔹 If an HTTP service is detected, nmap-vulners also attempts to identify the web stack, including the framework, CMS, or PHP version behind a reverse proxy. It analyzes Server and X-Powered-By headers, cookies, the page title, meta tags, filenames in script src, and page content. The plugin includes more than 700 rules. In version 2.0, the number of HTTP path fingerprints increased from 125 to 939, while parallelization kept the processing time at around 6 seconds per port.

🔹 If a product is identified but its version is unknown, the plugin makes a single request to a known file that contains version information, such as /CHANGELOG.txt for Drupal or /administrator/manifests/files/joomla.xml for Joomla. This works with Concrete5, Drupal, Jira, Joomla, Apache Tomcat, and WordPress.

🔹 Finally, if a service cannot be identified, Smart Audit can be used. The raw banner is sent to the Vulners server, which identifies the software and its version and then looks for related vulnerabilities. This is the only paid feature! Each unique request costs 1 credit, and results are cached. The number of requests is limited by the vulners.max_items parameter, which defaults to 32. Smart Audit can be disabled entirely with --script-args vulners.max_items=0.

The service data is then sent to the Vulners server, which returns a prioritized vulnerability report. For each vulnerability or exploit, the report includes its ID, SEVERITY level, CVSS and EPSS scores, Vulners AI score, KEV and EXP flags, and a link to its page on the Vulners website.

So, is an API key actually required?

🔹 The plugin can work without an API key. However, detection will use the legacy endpoint, and some vulnerability and exploit data will not be available.

🔹 Adding an API key, even without credits, enables the "EXP" flag for vulnerabilities and the "KEV" flag for both vulnerabilities and exploits. It also adds an EPSS score column, providing more complete prioritization: KEV → CISA SSVC Exploitation Active → exploits → EPSS → CVSS. So, an API key is recommended. 😉

🔹 If your API key has credits, the Smart Audit feature is also available (see above).

Installation

To install the plugin, simply run the one-line script. The installer automatically finds Nmap and its NSE script directory, installs the latest vulners.nse version, and removes old 1.x files. It then runs nmap --script-updatedb and verifies the installation. The --user and --prefix options let you specify the installation directory, while --uninstall removes the plugin. If needed, the installer prompts for a Vulners API key, validates it, and saves it to ~/.nmap/vulners.key with permissions set to 600.

The Vulners team has released an updated version Getsploit

The Vulners team has released an updated version of Getsploit. The utility allows you to search for public exploits in the Vulners.com database. It supports both an online mode (search queries are executed on the Vulners server) and a fully offline mode (exploit data from Vulners is downloaded to a local SQLite FTS5 index, which is then used for subsequent searches). I find the second option particularly interesting and useful. 😉 The data can be downloaded with a single command, getsploit --update, and the resulting database is ~1.7 GB in size.

You can then search for exploits locally, either by CVE or using full-text search:

$ getsploit --local CVE-2024-3094
$ getsploit --local "wordpress 4.7 remote code execution"

As a result, you get information about the exploits in the following format: ID, Title, and URL on the Vulners website.

If you use the "--mirror" option, the full text of the found exploits will be saved to separate files. This works with all Vulners exploit databases except githubexploit and gitee.

Why would you want to search for exploits in the first place? This can be very useful for enriching vulnerability data in your VM solution and, consequently, for better prioritization. It can also be quite useful for red teamers to keep track of new exploitation tools as they emerge. 😉

How much does it cost? Each getsploit update uses 10 credits. According to the pricing, the free plan currently includes 100 credits per month. So, if you update the exploit data once every 3 days, you can use it completely free of charge. 🆓 For $600, you can get 600 credits per month, which is enough to update getsploit roughly twice a day.

August In the Trend of VM (#30): vulnerabilities in ViPNet Client, the Microsoft Windows kernel, and Microsoft SharePoint

August "In the Trend of VM" (#30): vulnerabilities in ViPNet Client, the Microsoft Windows kernel, and Microsoft SharePoint. I present the traditional monthly roundup of trending vulnerabilities according to Positive Technologies. In the previous July edition, there was just one vulnerability. This time, there are four.

🗞 Post on Habr (rus)
🗒 Digest on the PT website (rus)

🔻 RCE - ViPNet Client (BDU:2026-09885). The first trending vulnerability in a Russian-made product since the beginning of 2026. Its exploitation was discovered by Positive Technologies experts.

🔻 EoP - NT OS Kernel (CVE-2026-42980). The vulnerability allows an attacker to escalate privileges to NT AUTHORITY\SYSTEM level.

🔻 EoP - Microsoft SharePoint (CVE-2026-56164) and RCE - Microsoft SharePoint (CVE-2026-58644). Two actively exploited vulnerabilities in a popular platform for building corporate websites, managing documents, and collaborating.

August Microsoft Patch Tuesday

August Microsoft Patch Tuesday. A total of 401 vulnerabilities were addressed - 170 fewer than in July. One of the vulnerabilities is known to be actively exploited in the wild:

🔻 EoP - Windows Ancillary Function Driver for WinSock (CVE-2026-68820). A local attacker can exploit this vulnerability to gain SYSTEM-level privileges. There is a contradiction in Microsoft's description: the Exploit Code Maturity in CVSS is marked as "Unproven", while at the same time Microsoft states that the vulnerability is being exploited in the wild. 🤷‍♂️

Public exploits are available for two other vulnerabilities:

🔸 EoP - Windows User Profile Service (CVE-2026-62832). This vulnerability allows an authenticated attacker to elevate privileges to ADMINISTRATOR level. Rapid7 believes this vulnerability is related to the LegacyHive exploit, which was published on July 14.

🔸 EoP - Windows Kernel (CVE-2026-62737). This vulnerability allows an authenticated attacker to elevate privileges to SYSTEM level. An exploit has been publicly available since August 11.

Among the remaining vulnerabilities, the following stand out:

🔹 RCE - Windows DNS Server (CVE-2026-62878). This wormable vulnerability allows a remote unauthenticated attacker to execute code on a vulnerable server with elevated privileges. It is recommended to test and install the update as soon as possible, especially on Internet-facing DNS servers.

🔹 RCE - Windows Deployment Services TFTP Server (CVE-2026-62893). This vulnerability, discovered as part of the ZDI (Zero Day Initiative) program, allows an attacker to execute code without authentication or user interaction. TFTP has no authentication mechanism and is available remotely via UDP port 69. Any WDS server serving Windows Imaging Format (WIM) files via TFTP, which is the standard PXE boot scenario, is vulnerable. The issue results from the lack of validation of the existence of an object before performing operations on it. UDP port 69 should be blocked at the perimeter, but attackers could easily use this vulnerability for lateral movement within an organization. If you're using WDS for deployments, test and install this update quickly.

🔹 RCE - Windows DHCP Server (CVE-2026-62823). Successful exploitation of this vulnerability allows a remote unauthenticated attacker to execute arbitrary code from an adjacent network by sending a specially crafted packet that triggers a heap-based buffer overflow.

🔹 EoP - Microsoft Exchange (CVE-2026-62911). This vulnerability allows a remote authenticated attacker (with Privileges Required: Low according to CVSS) to gain control over the mailboxes of all Exchange users, send and read emails, and download attachments. This vulnerability was demonstrated at Pwn2Own Berlin. ZDI researchers provided Microsoft with working exploits.

🔹 RCE - Microsoft QUIC (CVE-2026-62815). This use-after-free vulnerability allows an unauthenticated attacker to execute arbitrary code on a target system by sending a specially crafted network packet. QUIC is an IETF-standardized transport protocol that runs over UDP instead of TCP and serves as the foundation for HTTP/3. The protocol is used by approximately 13.5 million websites.

🔹 Tampering - Windows Container Isolation FS Filter Driver (unionfs.sys) (CVE-2026-72971). This vulnerability reportedly allows an attacker to overwrite certain files. As a result, an attacker could perform an action within a container that could impact the host system.

About Remote Code Execution - Microsoft SharePoint (CVE-2026-58644) vulnerability

About Remote Code Execution - Microsoft SharePoint (CVE-2026-58644) vulnerability. Information about this vulnerability was published on July 14 as part of the July Microsoft Patch Tuesday. The vulnerability in Microsoft SharePoint Server, caused by a deserialization flaw (CWE-502), allows an attacker with Site Owner privileges or higher to inject and remotely execute arbitrary code on the SharePoint server. This can result in full server compromise, including the exfiltration of corporate documents and data, their modification or deletion, compromise of credentials accessible to the server, and further lateral movement into the organization's internal infrastructure.

The authentication requirement, of course, makes exploitation of the vulnerability more difficult. However, an attacker could potentially leverage the previously disclosed EoP vulnerability CVE-2026-56164. At the same time, there is currently no confirmation that these vulnerabilities have been exploited together as part of a single attack chain.

👾 Microsoft experts flagged this vulnerability as being exploited in the wild on the day of Patch Tuesday. Two days later, on July 16, the vulnerability was added to the CISA KEV catalog. Details of the attacks are not yet known.

🛠 No public exploits have been observed so far.

⚙️ Updates are available for Microsoft SharePoint Server 2016, 2019, and Subscription Edition.

About Elevation of Privilege - Microsoft SharePoint (CVE-2026-56164) vulnerability.

About Elevation of Privilege - Microsoft SharePoint (CVE-2026-56164) vulnerability. The vulnerability was disclosed in the July Microsoft Patch Tuesday release on July 14. The vulnerability, related to missing authentication for a critical function (CWE-306), allows an unauthenticated attacker to remotely elevate their privileges.

It is quite interesting that the CVSS scores for the vulnerability differ significantly between Microsoft's website and the NVD.

🔹 Microsoft: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N (5.3 MEDIUM)

🔹 NVD: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H (9.8 CRITICAL)

As can be seen, the difference is that Microsof's experts consider the impact of successful exploitation on integrity to be low, while the NVD rates the impact on confidentiality, integrity, and availability as high. This once again highlights the subjective nature of CVSS as a vulnerability prioritization tool. 😉

👾 Microsoft experts flagged this vulnerability as being exploited in the wild on the day of Patch Tuesday. The vulnerability was also added to the CISA KEV catalog on the same day. Microsoft credited Mandiant Incident Response for reporting this vulnerability, which suggests that Mandiant may have been involved in identifying the exploitation activity. There are currently no publicly available details regarding the attacks. However, according to Bleeping Computer, this vulnerability may have been exploited in an attack against the Swiss Federal Office of Information Technology, Systems and Telecommunication (BIT) reported on July 28. During the incident, credentials for around 200 user and technical accounts were compromised on Internet-facing SharePoint servers. The investigation did not reveal any other data breaches. According to BIT, SharePoint vulnerabilities from the July Microsoft Patch Tuesday were exploited on the servers, although the specific CVEs were not disclosed.

🛠 An exploit for the vulnerability has been available on GitHub since August 6. According to the exploit author's description, the vulnerability allows a remote unauthenticated attacker to elevate privileges to the level of Farm Administrator. By abusing request processing and routing mechanisms, an attacker can force a vulnerable server to fall back to an elevated security context instead of rejecting an unauthenticated request. This enables the attacker to access information about site collections, users, and server configuration, add administrators, and execute commands.

⚙️ Updates are available for Microsoft SharePoint Server 2016, 2019, and Subscription Edition. In addition to installing the updates, Microsoft experts recommend enabling the AMSI antimalware scanning interface on the server and setting the Request Body Scan mode to Full to reduce the risk of exploitation.

About Elevation of Privilege - NT OS Kernel (CVE-2026-42980) vulnerability

About Elevation of Privilege - NT OS Kernel (CVE-2026-42980) vulnerability. Information about this vulnerability was disclosed as part of the June Microsoft Patch Tuesday on June 9. The vulnerability was not specifically highlighted in Microsoft Patch Tuesday reviews published by VM vendors. This Microsoft Windows NT OS Kernel elevation of privilege vulnerability is caused by improper handling of integer values during data construction in the Windows Management Instrumentation (WMI) subsystem, resulting in an out-of-bounds write. Successful exploitation allows a local attacker with low privileges (a standard user account) to escalate privileges to NT AUTHORITY\SYSTEM. Obtaining NT AUTHORITY\SYSTEM privileges grants full control over the affected host, enabling an attacker to execute arbitrary commands, modify security settings, access protected data, and use the compromised host as a foothold for further lateral movement within the target environment.

🛠 On July 7, a detailed write-up describing the exploitation of this vulnerability was published. A public proof-of-concept (PoC) exploit is also available on GitHub.

👾 There is currently no evidence of in-the-wild exploitation of this vulnerability.
