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

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

• CVE-2024-29745 Android Pixel Information Disclosure Vulnerability
• CVE-2024-29748 Android Pixel Privilege Escalation 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.

Today, CISA published a new dedicated High-Risk Communities webpage comprised of cybersecurity resources to support civil society communities at heighted risk of digital security threats, including cyber hygiene guidance, a repository of local cyber volunteer programs, and free or discounted tools and services.

Despite their vulnerability to advanced cyber threats, many civil society organizations operate on lean budgets and cannot significantly invest in cybersecurity. CISA’s High-Risk Communities webpage provides resources specifically for civil society organizations, such as:

• Project Upskill, a suite of cyber hygiene guides designed to arm individuals of high-risk organizations with simple steps to meaningfully improve their cyber hygiene.
• Cybersecurity Resources for High-Risk Communities, which offers a wide selection of free or steeply discounted tools and services.
• Cyber Volunteer Resource Center, a repository of cyber volunteer programs across the country that provide free, hands-on cybersecurity support to under-resourced organizations.

For more information on the initiative, read Associate Director Clayton Roman’s blog post, JCDC Working and Collaborating to Build Cyber Defense for Civil Society and High-Risk Communities. Visit Joint Cyber Defense Collaborative to learn more about the planning effort that aided in developing these valuable resources.
