CVE-2025-30412 is a critical security vulnerability classified under CWE-1390, affecting Acronis Cyber Protect versions 15 and 16 on both Linux and Windows platforms prior to builds 41800 and 39938 respectively. The flaw arises from improper authentication mechanisms within the software, which allows unauthenticated remote attackers to gain unauthorized access to sensitive data and perform unauthorized data manipulation. The vulnerability does not require any user interaction or privileges, making it remotely exploitable over the network with low attack complexity. The CVSS v3.0 score of 10 reflects the vulnerability’s severe impact on confidentiality, integrity, and availability, with a scope change indicating that the exploit can affect resources beyond the initially vulnerable component. Although no public exploits have been reported yet, the critical nature of the flaw and the widespread use of Acronis Cyber Protect in enterprise backup and cybersecurity solutions make this a high-risk issue. The vulnerability could lead to data breaches, loss of data integrity, and potential disruption of backup and recovery operations, severely impacting organizational security posture. The lack of available patches at the time of reporting necessitates immediate mitigation efforts to reduce exposure.

The impact of CVE-2025-30412 is extensive and severe for organizations worldwide relying on Acronis Cyber Protect for backup and cybersecurity. Successful exploitation can lead to unauthorized disclosure of sensitive data, including potentially critical backup data or system configurations, compromising confidentiality. Attackers can also manipulate data, undermining data integrity and trustworthiness of backups, which could result in corrupted recovery points or ransomware-like scenarios. The availability of backup services may be disrupted, affecting business continuity and disaster recovery capabilities. Given the critical role of Acronis Cyber Protect in protecting enterprise environments, this vulnerability could facilitate lateral movement within networks, data exfiltration, and sabotage of recovery processes. Organizations in sectors such as finance, healthcare, government, and critical infrastructure are particularly at risk due to the sensitive nature of their data and reliance on robust backup solutions.

1. Immediately monitor Acronis official channels for patches or updates addressing CVE-2025-30412 and apply them as soon as they become available. 2. Until patches are released, restrict network access to Acronis Cyber Protect management interfaces using firewalls and network segmentation to limit exposure to trusted administrators only. 3. Implement strict access controls and multi-factor authentication on management consoles to reduce the risk of unauthorized access. 4. Conduct thorough logging and monitoring of all access and activities related to Acronis Cyber Protect to detect anomalous behavior indicative of exploitation attempts. 5. Regularly audit backup data integrity and verify recovery points to identify any unauthorized data manipulation early. 6. Employ intrusion detection and prevention systems (IDS/IPS) tuned to detect suspicious activity targeting backup infrastructure. 7. Educate IT and security teams about this vulnerability and ensure incident response plans include scenarios involving backup system compromise. 8. Consider isolating backup servers from general network traffic and restrict administrative access to dedicated secure management networks.
