CVE-2025-8207 is a medium-severity vulnerability identified in version 3.6.23 of the Canara ai1 Mobile Banking App for Android. The root cause lies in the improper export of Android application components due to incorrect processing of the AndroidManifest.xml file, specifically related to the component com.canarabank.mobility. In Android applications, components such as activities, services, broadcast receivers, and content providers can be exported to allow interaction with other apps or system components. Improper export means that components intended to be private or restricted are accessible to other apps or users, potentially enabling unauthorized access or manipulation. This vulnerability requires local access, meaning an attacker must have physical or logical access to the device to exploit it. No user interaction or authentication is required beyond local access, and the attack complexity is low. The vulnerability affects confidentiality, integrity, and availability to a limited extent, as unauthorized access to exported components could lead to information leakage, unauthorized operations, or disruption of app functionality. The vendor was notified but did not respond, and no patches have been released. Although no known exploits are currently in the wild, the public disclosure increases the risk of exploitation. The CVSS 4.0 score is 4.8, reflecting a medium severity with low attack complexity but limited scope and impact. This vulnerability is particularly concerning for banking apps, as improper component exposure could be leveraged to bypass security controls or access sensitive banking functions on compromised devices.

For European organizations, especially financial institutions and their customers using the Canara ai1 Mobile Banking App, this vulnerability poses a moderate risk. Exploitation could allow attackers with local access to compromise the confidentiality of sensitive banking data or interfere with app operations, potentially leading to fraudulent transactions or data leakage. While the requirement for local access limits remote exploitation, the risk remains significant in scenarios where devices are lost, stolen, or compromised by malware. European banks and customers relying on this app may face reputational damage, regulatory scrutiny, and financial losses if this vulnerability is exploited. Additionally, the lack of vendor response and patch availability increases the window of exposure. Organizations with employees or customers using this app should be aware of the risk and consider mitigating controls to reduce potential impact.

1. Immediate mitigation should focus on limiting local access to devices running the vulnerable app version. This includes enforcing strong device authentication (PIN, biometrics), enabling device encryption, and educating users on securing their devices against theft or unauthorized access. 2. Organizations should monitor for any suspicious activity on devices with the app installed, including unusual app behavior or unauthorized access attempts. 3. Since no patch is currently available, consider restricting or disabling the use of the vulnerable app version within the organization until a fix is released. 4. Employ mobile device management (MDM) solutions to enforce app version control and restrict installation of vulnerable versions. 5. Encourage users to update the app promptly once a patched version is released. 6. Conduct security assessments of other banking apps to ensure similar improper export issues are not present. 7. For developers and security teams, review AndroidManifest.xml configurations to ensure components are explicitly marked as non-exported unless necessary, and implement least privilege principles for app components.
