As of now, the vulnerability is in a deferred status, indicating that while it is recognized, further action may be pending. Nonetheless, proactive measures should be taken to safeguard systems against potential exploitation.
Vulnerability Details
The vulnerability allows for local privilege escalation due to DLL hijacking. Affected products include Acronis Cyber Protect Cloud Agent (Windows) prior to build 39378. The CVSS score of 6.3 indicates a medium severity level, primarily due to the high impact on confidentiality and integrity, while availability remains unaffected.
This vulnerability is classified under CWE-426, which pertains to the 'DLL hijacking' category. The publication date of this vulnerability was January 31, 2025, with the last modification on April 15, 2026.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of DLL files, allowing attackers to hijack them for privilege escalation. The attack vector is local, which means that an attacker must have local access to the system to exploit this vulnerability. The attack complexity is high, requiring low privileges and no user interaction.
The confidentiality impact is high as successful exploitation could lead to unauthorized access to sensitive information, while integrity impact is also high due to potential alterations to critical system components. However, there is no impact on availability.
Risk & Impact Analysis
The real-world risk associated with CVE-2025-24829 involves local privilege escalation that could allow attackers to gain elevated access rights to the system. If exploited, this vulnerability could facilitate further attacks, including data exfiltration and system compromise. Organizations should assess their exposure and the potential blast radius of this vulnerability.
Given the CVSS score of 6.3, organizations should address this vulnerability in their priority patch cycle. The deferred status does not diminish the urgency of remediation; proactive measures are essential to mitigate risks.
