CVE-2025-57452 is a vulnerability identified in the realme BackupRestore application, specifically version 15.1.12_2810c08_250314. The vulnerability arises from improper handling of URI schemes within the component com.coloros.pc.PcToolMainActivity. This flaw allows local attackers to craft malicious Android Debug Bridge (ADB) intents that can cause the application to crash and potentially execute cross-site scripting (XSS) attacks. The vulnerability is triggered locally, meaning an attacker must have local access to the device or system to exploit it. The improper URI scheme handling indicates that the application does not correctly validate or sanitize the input received via ADB intents, which can be manipulated to inject malicious scripts or cause denial of service through crashes. Although no known exploits are currently reported in the wild and no CVSS score has been assigned, the vulnerability poses a risk due to the potential for privilege escalation or data manipulation via XSS, which could compromise the integrity and availability of the BackupRestore app's functionality. The lack of patch information suggests that a fix may not yet be available, emphasizing the need for caution and mitigation.

For European organizations, the impact of this vulnerability depends largely on the deployment of realme devices running the affected BackupRestore app version within their environment. Organizations that use realme smartphones or devices for business operations, especially those relying on BackupRestore for data management, could face risks including application crashes leading to potential data loss or service disruption. The XSS potential could allow attackers with local access to execute scripts that might steal sensitive data or manipulate backup processes, undermining data integrity. While exploitation requires local access, in environments where devices are shared, or where attackers can gain physical or remote local access (e.g., through compromised endpoints), the threat becomes more significant. This vulnerability could also be leveraged as part of a multi-stage attack to escalate privileges or move laterally within a network. Given the increasing use of mobile devices in European enterprises and the sensitivity of backup data, the vulnerability could impact confidentiality, integrity, and availability of critical data.

European organizations should implement several specific measures to mitigate this vulnerability: 1) Restrict local access to devices running the realme BackupRestore app by enforcing strong physical security controls and device access policies. 2) Disable or tightly control ADB access on devices, as ADB intents are the attack vector; ensure ADB is only enabled when necessary and only for trusted users. 3) Monitor and audit ADB connections and intents for unusual or unauthorized activity to detect potential exploitation attempts. 4) Apply application whitelisting and runtime protections to prevent unauthorized code execution triggered by malicious intents. 5) Engage with realme or device vendors to obtain patches or updates addressing this vulnerability and prioritize timely deployment once available. 6) Educate users about the risks of connecting devices to untrusted computers or networks that could exploit ADB interfaces. 7) Consider network segmentation and endpoint protection strategies to limit the impact of compromised devices within organizational infrastructure.
