An exploit for the vulnerability allows unauthenticated attackers to escape a virtual file system sandbox to download system files and potentially achieve RCE.

Just like you should check the quality of the ingredients before you make a meal, it's critical to ensure the integrity of AI training data.

Today, Cisco released security updates to address ArcaneDoor—exploitation of Cisco Adaptive Security Appliances (ASA) devices and Cisco Firepower Threat Defense (FTD) software. A cyber threat actor could exploit vulnerabilities ( CVE-2024-20353, CVE-2024-20359, CVE-2024-20358) to take control of an affected system. Cisco has reported active exploitation of CVE 2024-20353 and CVE-2024-20359 and CISA has added these vulnerabilities to its Known Exploited Vulnerabilities Catalog. CISA strongly encourages users and administrators to apply the necessary updates, hunt for any malicious activity, report positive findings to CISA, and review the following articles for more information: Cisco Blog: ArcaneDoor - New espionage-focused campaign found targeting perimeter network devices Cisco Event Response: Attacks Against Cisco Firewall Platforms

CISA has added three new vulnerabilities to its Known Exploited Vulnerabilities Catalog, based on evidence of active exploitation. CVE-2024-20353 Cisco ASA and FTD Denial of Service Vulnerability CVE-2024-20359 Cisco ASA and FTD Privilege Escalation Vulnerability CVE-2024-4040 CrushFTP VFS Sandbox Escape 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.

A while back I got an email from Perry, one of our readers who was having a problem using my cvescan script, which I covered in a 3 part story back in 2021:
