CISA Adds Ten Known Exploited Vulnerabilities to Catalog

CISA has added ten new vulnerabilities to its Known Exploited Vulnerabilities Catalog, based on evidence of active exploitation.

  • CVE-2013-3163 Microsoft Internet Explorer Memory Corruption Vulnerability
  • CVE-2014-1776 Microsoft Internet Explorer Memory Corruption Vulnerability
  • CVE-2017-7494 Samba Remote Code Execution Vulnerability

  • CVE-2022-38181 Arm Mali GPU Kernel Driver Use-After-Free Vulnerability
  • CVE-2023-0266 Linux Kernel Use-After-Free Vulnerability
  • CVE-2022-3038 Google Chrome Use-After-Free Vulnerability
  • CVE-2022-22706 Arm Mali GPU Kernel Driver Unspecified Vulnerability

These types of vulnerabilities are frequent attack vectors for malicious cyber actors and pose significant risks to the federal enterprise. Note: To view other newly added vulnerabilities in the catalog, click on the arrow in the “Date Added to Catalog” column—which will sort by descending dates.

Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities established the Known Exploited Vulnerabilities Catalog as a living list of known Common Vulnerabilities and Exposures (CVEs) that carry significant risk to the federal enterprise. BOD 22-01 requires Federal Civilian Executive Branch (FCEB) agencies to remediate identified vulnerabilities by the due date to protect FCEB networks against active threats. See the BOD 22-01 Fact Sheet for more information.

Although BOD 22-01 only applies to FCEB agencies, CISA strongly urges all organizations to reduce their exposure to cyberattacks by prioritizing timely remediation of Catalog vulnerabilities as part of their vulnerability management practice. CISA will continue to add vulnerabilities to the catalog that meet the specified criteria.

CISA Releases One Industrial Control Systems Advisory

CISA released one Industrial Control Systems (ICS) advisory on March 30, 2023. This advisory provides timely information about current security issues, vulnerabilities, and exploits surrounding ICS. 

CISA encourages users and administrators to review the newly released ICS advisories for technical details and mitigations. 

Supply Chain Attack Against 3CXDesktopApp

CISA is aware of open-source reports describing a supply chain attack against 3CX software and their customers. According to the reports, 3CXDesktopApp — a voice and video conferencing app — was trojanized, potentially leading to multi-staged attacks against users employing the vulnerable app.

CISA urges users and organizations to review the following reports for more information, and hunt for the listed indicators of compromise (IOCs) for potential malicious activity:

Untitled Goose Tool Aids Hunt and Incident Response in Azure, Azure Active Directory, and Microsoft 365 Environments

Today, CISA released the Untitled Goose Tool to help network defenders detect potentially malicious activity in Microsoft Azure, Azure Active Directory (AAD), and Microsoft 365 (M365) environments. The Untitled Goose Tool offers novel authentication and data gathering methods for network defenders to use as they interrogate and analyze their Microsoft cloud services. The tool enables users to:

  • Export and review AAD sign-in and audit logs, M365 unified audit log (UAL), Azure activity logs, Microsoft Defender for IoT (internet of things) alerts, and Microsoft Defender for Endpoint (MDE) data for suspicious activity.
  • Query, export, and investigate AAD, M365, and Azure configurations.
  • Extract cloud artifacts from Microsoft’s AAD, Azure, and M365 environments without performing additional analytics. 
  • Perform time bounding of the UAL.
  • Extract data within those time bounds. 
  • Collect and review data using similar time bounding capabilities for MDE data.

Untitled Goose Tool was developed by CISA with support from Sandia National Laboratories. Network defenders can see the Untitled Goose Tool fact sheet and visit the Untitled Goose Tool GitHub repository to get started.

JCDC Cultivates Pre-Ransomware Notification Capability

In today’s blog post, Associate Director of the Joint Cyber Defense Collaborative (JCDC) Clayton Romans highlighted recent successes of pre-ransomware notification and its impact in reducing harm from ransomware intrusions. With pre-ransomware notifications, organizations can receive early warning and potentially evict threat actors before they can encrypt and hold critical data and systems for ransom. Using this proactive cyber defense capability, CISA has notified more than 60 entities of early-stage ransomware intrusions since January 2023, including critical infrastructure organizations in the Energy, Healthcare and Public Health, Water and Wastewater Systems sectors, as well as the education community.

The pre-encryption ransomware notification was cultivated with the help of the cybersecurity research community and through CISA’s relationships with infrastructure providers and cyber threat intelligence companies.

For more information, visit #StopRansomware. To report early-stage ransomware activity, visit Report Ransomware. CISA also encourages stakeholders and network defenders to review associate director Romans’ post, Getting Ahead of the Ransomware Epidemic: CISA’s Pre-Ransomware Notifications Help Organizations Stop Attacks Before Damage Occurs, to learn more about CISA’s Pre-Ransomware Notification Initiative.
