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

• CVE-2023-41064 Apple iOS, iPadOS, and macOS ImageIO Buffer Overflow
• CVE-2023-41061 Apple iOS, iPadOS, and watchOS Wallet Code Execution 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.

3.4 RESEARCHER

Soufian El Yadmani of Darktrace / CSIRT.global reported these vulnerabilities to CISA.

4. MITIGATIONS

In 2023, Dover Fueling Solutions announced end-of-life for MAGLINK LX 3 and released MAGLINK LX 4. However, MAGLINK LX 3 version 3.4.2.2.6 and MAGLINK LX 4 fixes these vulnerabilities.

CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities, such as:

• Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet.
• Locate control system networks and remote devices behind firewalls and isolating them from business networks.
• When remote access is required, use more secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize VPN is only as secure as the connected devices.

CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.

CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov/ics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.

CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets.

Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01B–Targeted Cyber Intrusion Detection and Mitigation Strategies.

Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.

No known public exploitation specifically targeting these vulnerabilities has been reported to CISA at this time.

5. UPDATE HISTORY

• September 07, 2023: Initial Publication

CISA has released actionable guidance for Federal Civilian Executive Branch (FCEB) agencies to help them evaluate and mitigate the risk of volumetric distributed denial-of-service (DDoS) attacks against their websites and related web services. The Capacity Enhancement Guide: Volumetric DDoS Against Web Services Technical Guidance:  

• Helps agencies prioritize DDoS mitigations based on mission and reputational impact. 
• Describes DDoS mitigation services so agencies can make risk-informed tradeoff decisions on how to use available resources most effectively. 

CISA encourages FCEB agencies to review the guidance and apply the recommendations. Visit Capacity Enhancement Guides for Federal Agencies for more ways to reduce cybersecurity risk. 

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

• CVE-2023-33246 Apache RocketMQ Command Execution 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.

The Cybersecurity and Infrastructure Security Agency (CISA) has released an update to a previously published Cybersecurity Advisory (CSA), Threat Actors Exploiting Citrix CVE-2023-3519 to Implant Webshells. The CSA—originally released to warn network defenders of critical infrastructure organizations about threat actors exploiting CVE-2023-3519, an unauthenticated remote code execution (RCE) vulnerability affecting NetScaler (formerly Citrix) Application Delivery Controller (ADC) and NetScaler Gateway—contains victim information gathered in August 2023. Since July 2023, the Joint Cyber Defense Collaborative (JCDC) has facilitated continuous, real-time threat information sharing with and between partners on post-exploitation activity of CVE-2023-3519. JCDC consolidated and shared detection methods, threat actor tactics, techniques, and procedures (TTPs), and indicators of compromise (IOCs) received from industry and international partners. The updated CSA contains new TTPs as well as IOCs received from some of these partners and an additional victim.

CISA strongly urges all critical infrastructure organizations to review the advisory and follow the mitigation recommendations—such as prioritizing patching known exploited vulnerabilities like Citrix CVE-2023-3519.

To report incidents and anomalous activity, please contact CISA, either through the agency’s Incident Reporting System or the 24/7 Operations Center at report@cisa.gov or (888) 282-0870.  

CISA released two Industrial Control Systems (ICS) advisories on September 5, 2023. These advisories provide timely information about current security issues, vulnerabilities, and exploits surrounding ICS.
