Overview of the Active Exploitation of Veeam CVE-2024-40711
A critical vulnerability in Veeam Backup and Replication software, CVE-2024-40711, is being actively exploited by ransomware groups, according to cybersecurity researchers and federal agencies. This vulnerability, which has a severity score of 9.8 on the CVSS scale, was initially disclosed and patched in September 2024. Despite the patch, several threat actors have leveraged the flaw in ransomware attacks over the past month.
The Cybersecurity and Infrastructure Security Agency (CISA) added the vulnerability to its Known Exploited Vulnerabilities catalog on October 17, 2024, indicating that it is actively used in malicious campaigns. This flaw allows unauthorized attackers to execute arbitrary code remotely, making it a critical concern for organizations utilizing Veeam’s enterprise backup solution.
Ransomware Attacks Linked to the Vulnerability
Cybersecurity firm Sophos X-Ops reported that it has tracked at least four ransomware attacks exploiting the CVE-2024-40711 vulnerability earlier this month. These attacks have been linked to the Akira and Fog ransomware variants. According to Sophos, attackers typically gain access through compromised VPN gateways that lack multi-factor authentication, allowing them to penetrate systems more easily.
Sophos X-Ops stated in a post on the social platform X (formerly Twitter) that these exploits show a clear trend of how ransomware groups are exploiting software vulnerabilities long after they are disclosed and patched, pointing to the slow pace of patch adoption in many organizations.
Vulnerability Details and the Importance of Timely Patching
Veeam disclosed CVE-2024-40711 along with several other vulnerabilities on September 4, 2024. The vulnerability affects Veeam Backup and Replication version 12.1.2.172 and earlier builds. Although Veeam issued a patch as part of its Backup and Replication v12.2 update on August 28, 2024, many systems remain unpatched. This gap has given ransomware actors a window to exploit the vulnerability.
According to Heidi Monroe Kroft, Senior Director of Corporate Communications and Global Public Relations at Veeam, the company immediately informed all affected customers about the vulnerability and the availability of the patch. However, the persistence of exposed systems highlights the challenges organizations face in applying patches in a timely manner.
Exposed Systems and Industry Impact
Cybersecurity researchers have observed that a significant number of Veeam Backup and Replication systems remain exposed to this vulnerability. Himaja Motheram, a security researcher at Censys, reported that there were 2,833 exposed instances as of September 6, 2024, a number that has only slightly decreased to 2,784 as of mid-October. The vast majority of these exposed systems are located in Europe, with several industries, including healthcare and finance, at heightened risk.
The National Health Service (NHS) Digital arm in the U.K. issued a cybersecurity alert on October 11, 2024, warning healthcare organizations to take immediate action to secure their Veeam systems. Given the critical nature of healthcare data, organizations that fail to patch their systems could face significant data breaches or ransomware attacks that could disrupt essential services.
Ransomware Groups Targeting Veeam’s Popularity
Veeam Backup and Replication is widely used across industries for virtual, physical, and cloud data backups, making it a prime target for ransomware groups. Attackers seek to exploit software that is prevalent across enterprise environments because of the high potential for disruption.
Caitlin Condon, Director of Vulnerability Intelligence at Rapid7, emphasized the popularity of Veeam in enterprise environments as a key reason for its frequent targeting by adversaries. “More than 20% of Rapid7’s incident response cases in 2024 have involved Veeam being accessed or exploited in some manner, typically after an attacker has gained an initial foothold in the target environment,” she noted.
According to Condon, ransomware groups have exploited vulnerabilities in Veeam software in the past, sometimes months or even years after the flaws were disclosed. This trend highlights the sustained threat posed by unpatched systems, particularly those running widely used enterprise solutions like Veeam.
Proof-of-Concept Exploits Released Shortly After Disclosure
Within days of Veeam’s initial disclosure of CVE-2024-40711, partial proof-of-concept exploit code was made publicly available. This accelerated the timeline for attackers to craft and launch exploits targeting unpatched systems. Vulnerability researchers at Censys and Rapid7 sounded the alarm shortly after the disclosure, warning organizations of the risks posed by delayed patch adoption.
Industry Responses to the Threat
In response to the ongoing threat posed by this vulnerability, various security organizations have urged enterprises to prioritize patching their Veeam Backup and Replication systems. The Cybersecurity and Infrastructure Security Agency (CISA) continues to monitor the situation, and security vendors like Sophos and Rapid7 are closely tracking ransomware activity related to the exploit.
However, Veeam has not disclosed how many of its customers have patched their systems or have been affected by ransomware attacks exploiting the flaw.
