The vulnerability identified as CVE-2022-30992 represents a critical open redirect flaw in Acronis Cyber Protect 15 versions prior to build 29240 across both Linux and Windows platforms. This security weakness allows malicious actors to manipulate query parameters in HTTP requests to redirect users to arbitrary external domains without proper validation or user consent. The issue stems from insufficient input sanitization within the application's URL handling mechanisms, creating a pathway for attackers to exploit the system's trust in legitimate internal redirects.
The technical implementation of this vulnerability resides in the application's failure to properly validate and sanitize user-supplied query parameters that are subsequently used to construct redirect URLs. When users interact with the affected system, they may encounter links or forms that accept user input containing redirect destinations. The system processes these inputs without adequate verification, allowing attackers to inject malicious URLs that bypass normal security controls. This flaw operates at the application layer and can be exploited through web-based interfaces where users are prompted to provide input that gets processed as part of redirect logic.
The operational impact of this vulnerability extends beyond simple redirection attacks and can facilitate more sophisticated social engineering campaigns. Attackers can leverage this weakness to create phishing pages that appear legitimate to users, potentially leading to credential theft, malware distribution, or data exfiltration. The vulnerability creates a trust relationship manipulation scenario where users are unknowingly directed from a trusted internal system to malicious external sites. This opens pathways for man-in-the-middle attacks, session hijacking, and other advanced persistent threat techniques that rely on user trust and behavior manipulation.
Organizations utilizing affected Acronis Cyber Protect versions face significant security risks including potential unauthorized access to sensitive systems and data. The vulnerability can be exploited through various attack vectors including email campaigns, compromised websites, or malicious advertisements that direct users to exploit the redirect functionality. Security teams should consider this vulnerability as a potential entry point for broader attacks and implement immediate mitigations while awaiting official patches. The flaw demonstrates poor input validation practices and highlights the importance of implementing proper security controls at all levels of application development and deployment.
The mitigation strategy for CVE-2022-30992 involves immediate deployment of the vendor-provided security patches and updates for Acronis Cyber Protect 15. Organizations should also implement network-level controls such as web application firewalls that can detect and block suspicious redirect patterns, while monitoring for anomalous traffic patterns that might indicate exploitation attempts. Additionally, security awareness training for users should emphasize the importance of verifying URLs and avoiding unexpected redirects. This vulnerability aligns with CWE-601 open redirect weaknesses and can be mapped to ATT&CK technique T1566.001 for credential harvesting through phishing. Regular security assessments and input validation reviews should be conducted to prevent similar issues in other applications and systems.
