CISA and FBI Release Secure by Design Alert on Eliminating Cross-Site Scripting Vulnerabilities

 ​Today, CISA and FBI released a Secure by Design Alert, Eliminating Cross-Site Scripting Vulnerabilities, as a part of our ongoing effort to reduce the prevalence of vulnerability classes at scale. Vulnerabilities like cross-site scripting (XSS) continue to appear in software, enabling threat actors to exploit them. However, cross-site scripting vulnerabilities are preventable and should not be present in software products. 

CISA and FBI urge CEOs and other business leaders at technology manufacturers to direct their technical leaders/teams to review past instances of these defects and create a strategic plan to prevent them in the future.  

Visit our website to learn more about the principles of Secure by Design, take the Secure by Design Pledge, and stay informed on the latest Secure by Design Alerts.

New CISA Plan Aligns Federal Agencies in Cyber Defense

 ​Today, the Cybersecurity and Infrastructure Security Agency (CISA) released the Federal Civilian Executive Branch (FCEB) Operational Cybersecurity Alignment (FOCAL) Plan. Developed in collaboration with FCEB agencies, this plan provides standard, essential components of enterprise operational cybersecurity and aligns the collective operational defense capabilities across the federal enterprise.
Currently, federal agencies maintain their own networks and system architectures—and they independently manage their cyber risk. CISA’s FOCAL plan aligns the federal enterprise, empowering agencies to better address the dynamic cyber threat environment collectively. The plan recommends actions that substantively advance operational cybersecurity improvements and alignment goals. 
For additional guidance, visit CISA’s Securing Networks web page.

CISA Adds Two Known Exploited Vulnerabilities to Catalog

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

CVE-2024-43461 Microsoft Windows MSHTML Platform Spoofing Vulnerability
CVE-2024-6670 Progress WhatsUp Gold SQL Injection Vulnerability

These types of vulnerabilities are frequent attack vectors for malicious cyber actors and pose significant risks to the federal enterprise.
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 has added two new vulnerabilities to its Known Exploited Vulnerabilities Catalog, based on evidence of active exploitation.

CVE-2024-43461 Microsoft Windows MSHTML Platform Spoofing Vulnerability
CVE-2024-6670 Progress WhatsUp Gold SQL Injection Vulnerability

These types of vulnerabilities are frequent attack vectors for malicious cyber actors and pose significant risks to the federal enterprise.

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.

CISA Releases Analysis of FY23 Risk and Vulnerability Assessments

 ​CISA has released an analysis and infographic detailing the findings from the 121 Risk and Vulnerability Assessments (RVAs) conducted across multiple critical infrastructure sectors in fiscal year 2023 (FY23).
The analysis details a sample attack path including tactics and steps a cyber threat actor could follow to compromise an organization with weaknesses representative of those CISA observed in FY23 RVAs. The infographic highlights the most successful techniques for each tactic that RVAs documented. Both the analysis and infographic map threat actor behavior to the MITRE ATT&CK® framework.
CISA encourages network defenders to review the analysis and infographic and apply the recommended mitigations to protect against the observed tactics and techniques.
