CVE-2025-7379 is a medium-severity security vulnerability affecting ASUSTOR ADM's DataSync Center versions 1.1.0 before 1.1.0.r207 and 1.2.0 before 1.2.0.r206. The vulnerability is classified as CWE-352, indicating a Cross-Site Request Forgery (CSRF) issue. CSRF vulnerabilities allow attackers to trick authenticated users into submitting unwanted actions to a web application in which they are currently authenticated. This particular vulnerability involves a security bypass via Reverse Tabnabbing, a phishing technique where an attacker manipulates the content of the original browser tab after a user clicks a malicious link. Reverse Tabnabbing can lead to credential theft and other security risks by replacing the original tab's content with a malicious page, potentially deceiving users into entering sensitive information. The CVSS 4.0 score is 5.2 (medium), reflecting that the attack requires high attack complexity, privileges, and user interaction, with limited impact on confidentiality, integrity, and availability. The vulnerability affects network-accessible services (AV:N) and requires the attacker to have privileges and user interaction to exploit. No known exploits are currently reported in the wild, and no patches are linked yet. The vulnerability's presence in DataSync Center, a component likely used for file synchronization and backup on ASUSTOR NAS devices, means that exploitation could compromise user credentials and potentially allow unauthorized actions within the ADM environment.

For European organizations using ASUSTOR ADM devices, especially those leveraging DataSync Center for critical data synchronization and backup, this vulnerability poses a risk of credential theft and unauthorized actions through phishing attacks exploiting Reverse Tabnabbing. Compromise of credentials could lead to unauthorized access to sensitive data stored on NAS devices, disruption of data synchronization processes, and potential lateral movement within internal networks. Given the medium severity and the requirement for user interaction and privileges, the threat is more pronounced in environments where users frequently access ADM interfaces via web browsers and may be susceptible to phishing. The impact could be significant in sectors with high data sensitivity such as finance, healthcare, and government institutions. Additionally, since NAS devices often serve as centralized storage, any compromise could affect data integrity and availability, impacting business continuity.

1. Apply patches and updates from ASUSTOR as soon as they become available for DataSync Center and ADM to address this vulnerability. 2. Implement strict browser security policies to mitigate Reverse Tabnabbing, such as using rel="noopener noreferrer" on all external links to prevent malicious tab manipulation. 3. Educate users on phishing risks and the dangers of interacting with suspicious links, emphasizing caution when accessing ADM web interfaces. 4. Employ multi-factor authentication (MFA) on ADM accounts to reduce the risk of credential compromise leading to unauthorized access. 5. Restrict ADM web interface access to trusted networks or via VPN to limit exposure to external attackers. 6. Monitor ADM logs for unusual activities indicative of CSRF or phishing exploitation attempts. 7. Use Content Security Policy (CSP) headers to restrict the sources of executable scripts and reduce the attack surface for web-based attacks.
