CVE-2022-34910 is a medium-severity vulnerability identified in the A4N (Aremis 4 Nomad) Android application version 1.5.0. The vulnerability arises from the application's insecure handling of user credentials within its local database. Specifically, the application stores user passwords in cleartext without any encryption or hashing. This insecure storage practice exposes sensitive authentication data to potential attackers who gain access to the device. Since the database is local to the device, any attacker with physical or remote access to the device's storage can extract the stored passwords. This vulnerability is particularly concerning in scenarios where multiple users share the same device, as it allows an attacker to retrieve passwords of other users who have used the device. The CVSS 3.1 score of 4.1 reflects a medium severity, with a high impact on confidentiality but no impact on integrity or availability. The attack complexity is high, requiring local access and privileges (PR:H), and no user interaction is needed. The vulnerability is categorized under CWE-312, which relates to cleartext storage of sensitive information. No known exploits are currently reported in the wild, and no patches or vendor mitigations have been published as of the provided data. This vulnerability highlights poor security design in credential management within mobile applications, emphasizing the need for secure storage mechanisms such as encrypted databases or Android's Keystore system.

For European organizations, especially those whose employees or users utilize the A4N Android application on shared or corporate devices, this vulnerability poses a risk of credential compromise. Attackers with access to a device could extract stored passwords, potentially leading to unauthorized access to user accounts within the application or related systems if password reuse occurs. Although the vulnerability requires local access and elevated privileges, the risk increases in environments where devices are shared, lost, or stolen. This could lead to data breaches, unauthorized data access, and potential lateral movement within organizational networks if credentials are reused. The confidentiality of user credentials is directly impacted, which can undermine trust in the application and the organization's security posture. However, since the vulnerability does not affect data integrity or availability, the immediate operational impact is limited to information disclosure. The medium severity indicates that while exploitation is not trivial, the consequences of successful exploitation warrant attention, particularly in sectors handling sensitive or regulated data.

European organizations should implement several targeted mitigation strategies beyond generic advice: 1) Avoid using or deploying the vulnerable version (1.5.0) of the A4N application until a patched version is available. 2) Enforce strict device access controls, including strong authentication and encryption, to prevent unauthorized local access. 3) Limit device sharing among multiple users to reduce exposure risk. 4) Educate users about the risks of storing sensitive credentials on shared devices and encourage the use of unique, strong passwords to minimize damage from credential compromise. 5) Employ mobile device management (MDM) solutions to monitor and control application usage and enforce security policies. 6) Where possible, request or develop application updates that implement secure credential storage using Android's Keystore or encrypted databases. 7) Conduct regular audits of devices for unauthorized access or suspicious activity. 8) Encourage multi-factor authentication (MFA) for accounts accessed via the application to mitigate risks from password disclosure.
