CISA Adds Three Known Exploited Vulnerabilities to Catalog

Thu, 05/16/2024 - 8:00am

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

  • CVE-2014-100005 D-Link DIR-600 Router Cross-Site Request Forgery (CSRF) Vulnerability
  • CVE-2021-40655 D-Link DIR-605 Router Information Disclosure Vulnerability
  • CVE-2024-4761 Google Chromium V8 Out-of-Bounds Memory Write 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 and Partners Release Guidance for Civil Society Organizations on Mitigating Cyber Threats with Limited Resources

Tue, 05/14/2024 - 8:00am

CISA, in partnership with the Department of Homeland Security (DHS), the Federal Bureau of Investigation (FBI) and international partners, released Mitigating Cyber Threats with Limited Resources: Guidance for Civil Society. The joint guidance provides civil society organizations and individuals with recommended actions and mitigations to reduce the risk of cyber intrusions. Additionally, the guide encourages software manufactures to actively implement and publicly commit to Secure by Design practices that are necessary to help protect vulnerable and high-risk communities.

Civil society, comprised of organizations and individuals such as– nonprofit, advocacy, cultural, faith-based, academic, think tanks, journalist, dissident, and diaspora organizations, communities involved in defending human rights and advancing democracy–are considered high-risk communities. Often these organizations and their employees are targeted by state-sponsored threat actors who seek to undermine democratic values and interests.  

CISA and partners encourage civil society organizations and software manufacturers to review and implement the mitigations and practices in the joint guide to mitigate the threat posed by malicious cyber actors to civil society organizations. To learn more about secure by design principles and practices, visit CISA’s Secure by Design webpage. For more on protecting civil society, visit CISA’s Cybersecurity Resources for High-Risk Communities webpage.

CISA and FBI Release Secure by Design Alert to Urge Manufacturers to Eliminate Directory Traversal Vulnerabilities

Thu, 05/02/2024 - 8:00am

Today, CISA and the Federal Bureau of Investigation (FBI) released a joint Secure by Design Alert, Eliminating Directory Traversal Vulnerabilities in Software. This Alert was crafted in response to recent well-publicized threat actor campaigns that exploited directory traversal vulnerabilities in software (e.g., CVE-2024-1708, CVE-2024-20345) to compromise users of the software—impacting critical infrastructure sectors, including the Healthcare and Public Health Sector.

Additionally, this Alert highlights the prevalence, and continued threat actor exploitation of, directory traversal defects. Currently, CISA has listed 55 directory traversal vulnerabilities in our Known Exploited Vulnerabilities (KEV) catalog. Approaches to avoid directory traversal vulnerabilities are known, yet threat actors continue to exploit these vulnerabilities which have impacted the operation of critical services, including hospital and school operations.

CISA and the FBI urge software manufacturer executives to require their organizations to conduct formal testing to determine their products’ susceptibility to directory traversal vulnerabilities.

For more information on recommended principles and best practices to achieve this goal, visit CISA’s Secure by Design page. To catch up on the publications in this series, visit Secure by Design Alerts.

CISA and Partners Release Fact Sheet on Defending OT Operations Against Ongoing Pro-Russia Hacktivist Activity

Wed, 05/01/2024 - 8:00am

Today, CISA, in collaboration with U.S. and international partners, published a joint fact sheet, Defending OT Operations Against Ongoing Pro-Russia Hacktivist Activity. This fact sheet provides information and mitigations associated with cyber operations conducted by pro-Russia hacktivists who seek to compromise industrial control systems (ICS) and small-scale operational technology (OT) systems in North American and European critical infrastructure sectors, including Water and Wastewater Systems, Dams, Energy, and Food and Agriculture Sectors.

The pro-Russia hacktivist activity appears mostly limited to unsophisticated techniques that manipulate ICS equipment to create nuisance effects. However, investigations have identified that these actors are capable of techniques that pose physical threats against insecure and misconfigured OT environments.

CISA and partners encourage OT operators in critical infrastructure sectors to apply the recommendations listed in the fact sheet to defend against this activity. To learn more about secure by design principles and practices, visit CISA's Secure by Design webpage. For more information and guidance on protection against the most common and impactful threats, tactics, techniques, and procedures, visit CISA’s Cross-Sector Cybersecurity Performance Goals.
