CISA Adds One Known Exploited Vulnerability to Catalog

All CISA Advisories
Actively Exploited

Overview

The Cybersecurity and Infrastructure Security Agency (CISA) has added a new vulnerability, CVE-2008-4128, to its Known Exploited Vulnerabilities Catalog. This vulnerability affects Cisco IOS and is associated with cross-site request forgery, which allows attackers to exploit vulnerable systems. It poses significant risks, particularly for federal agencies, as it can lead to total control over affected assets after exploitation. CISA's Binding Operational Directive 26-04 emphasizes the need for federal agencies to prioritize rapid remediation of such high-risk vulnerabilities. While this directive primarily applies to federal agencies, CISA encourages all organizations to adopt similar practices for managing vulnerabilities effectively. Agencies are also urged to check for any compromises before applying patches to mitigate risks.

Key Takeaways

  • Active Exploitation: This vulnerability is being actively exploited by attackers. Immediate action is recommended.
  • Affected Systems: Cisco IOS systems vulnerable to CVE-2008-4128
  • Action Required: Federal agencies should prioritize applying security updates for CVE-2008-4128 as per BOD 26-04.
  • Timeline: Newly disclosed

Original Article Summary

CISA has added one new vulnerability to its Known Exploited Vulnerabilities (KEV) Catalog, based on evidence of active exploitation. CVE-2008-4128 Cisco IOS Cross-Site Request Forgery Vulnerability This type of vulnerability is a frequent attack vector for malicious cyber actors and poses significant risks to the federal enterprise. Binding Operational Directive (BOD) 26-04: Prioritizing Security Updates Based on Risk establishes vulnerability management requirements for Federal Civilian Executive Branch (FCEB) agencies. BOD 26-04 reinforces the importance of the KEV Catalog and requires federal agencies to prioritize rapid remediation of high-risk vulnerabilities, specifically those identified by Common Vulnerabilities and Exposures (CVEs) listed in CISA’s KEV Catalog on publicly exposed assets that grant total control of the asset post-exploitation, while deferring action for lower-risk vulnerabilities. BOD 26-04 further establishes basic expectations for when agencies must check whether threat actors compromised the system before the patch was applied. While BOD 26-04 applies only to FCEB agencies, CISA encourages all organizations to adopt risk-based vulnerability management and prioritize remediation of KEV Catalog vulnerabilities. CISA will continue to add vulnerabilities to the catalog that meet the specified criteria. Aware of an exploited vulnerability not currently listed in the KEV Catalog? Submit it for potential addition through CISA’s KEV Nomination Form. Potential KEV additions must have a CVE ID, evidence of exploitation, and clear mitigation guidance.
