Acronis Local Privilege Escalation via Input Validation Bypass

CVE-2026-41952 represents a local privilege escalation vulnerability affecting Acronis DeviceLock DLP and Cyber Protect Cloud Agent on Windows systems. The vulnerability stems from improper input validation, allowing an authenticated local attacker to bypass security controls and escalate their privileges to system or administrator level. This is particularly concerning for organizations relying on Acronis solutions for data loss prevention and endpoint protection, as it undermines the security posture of systems that should be protecting sensitive data. Affected versions include DeviceLock DLP before build 9.0.93212 and Cyber Protect Cloud Agent before build 42183, making patching an immediate priority for Windows environments.

While this CVE currently has no mapped MITRE ATT&CK techniques, Casky's 754 security skills—powered by Claude AI's extended reasoning capabilities—would identify the underlying attack patterns through behavioral analysis of privilege escalation attempts. Practitioners using Casky would observe findings related to suspicious process creation patterns, unexpected privilege token elevation, and anomalous Windows API calls that typically precede local privilege escalation exploits. The platform's skill set would flag improper validation enforcement in system calls and detect attempts to manipulate input parameters destined for privileged operations. Although this specific CVE lacks active MITRE technique attribution, Casky's detection framework would surface the technical indicators of privilege escalation (T1134 family techniques) that security teams must monitor, enabling defenders to spot similar input validation bypasses before they're formally classified in threat intelligence frameworks.
