NHS Warns of Active Exploitation of Critical Arcserve Vulnerabilities

The UK's National Health Service (NHS) has issued an urgent warning about the active exploitation of three critical vulnerabilities in Arcserve Unified Data Protection (UDP) software. The vulnerabilities, originally disclosed in March 2024, have been assigned the identifiers CVE-2024-0799, CVE-2024-0800, and CVE-2024-0801.

Why this matters: This warning highlights the critical importance of timely patching and proactive cybersecurity measures in safeguarding sensitive data, as the exploitation of these vulnerabilities can have far-reaching consequences for organizations and individuals alike. The incident also underscores the need for robust incident response plans to mitigate the impact of cyber attacks.

According to the NHS alert, these vulnerabilities pose significant risks if left unpatched, potentially leading to data theft, ransomware attacks, and sabotaged backups. The most severe of the three, CVE-2024-0799, is an authentication bypass vulnerability that allows attackers to perform privileged actions within the software. It has been assigned a critical CVSSv3 score of 9.8.

CVE-2024-0800, with a CVSSv3 score of 8.8, is a path traversal bug that enables attackers to upload malicious files with SYSTEM privileges. The third vulnerability, CVE-2024-0801, is a denial of service flaw that is still undergoing assessment.

In response to the active exploitation of these vulnerabilities, the NHS has "strongly encouraged" organizations to apply patches as set out in Arcserve's advisory. The Centre for Cybersecurity Belgium (CCB) has echoed this call to action, urging immediate patching to prevent potential attacks.

The CCB has also recommended that organizations upscale their monitoring and detection capabilities to identify any suspicious activity related to these vulnerabilities. This proactive approach aims to ensure a swift response in the event of an intrusion. As the CCB warns, "While patching appliances or software to the newest version may provide safety from future exploitation, it does not remediate historic compromise."

The exact timeline of the exploitation attempts remains unclear, but the NHS published its updated alert on May 9, 2024. This suggests that attackers have been actively targeting these vulnerabilities for some time, emphasizing the urgency for organizations to take immediate action.

Arcserve, a leading provider of data protection solutions, has acknowledged the severity of these vulnerabilities and has released patches to address them. The company is working closely with its customers to ensure the timely application of these critical updates.

The discovery of these vulnerabilities in Arcserve UDP software highlights the ongoing challenges faced by organizations in securing their data protection infrastructure. As cyber threats continue to evolve, it is crucial for businesses to remain vigilant, regularly update their systems, and have robust incident response plans in place. The active exploitation of the Arcserve vulnerabilities serves as a stark reminder of the importance of timely patching and proactive cybersecurity measures in safeguarding critical data assets.
