CVE-2022-45483 is a vulnerability identified in the thisAAY Lazy Mouse product, specifically affecting versions up to and including 2.0.1. The vulnerability is classified under CWE-319, which pertains to the cleartext transmission of sensitive information. In this case, the Lazy Mouse device transmits data, including keypresses, without encryption, allowing an attacker positioned as a man-in-the-middle (MitM) between the server and the connected device to intercept and view all transmitted data in cleartext. The vulnerability does not require user interaction or authentication to be exploited, but it does require the attacker to have network access with the capability to intercept traffic (local network or otherwise). The CVSS v3.1 score is 5.9 (medium severity), with the vector indicating network attack vector (AV:N), high attack complexity (AC:H), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), high confidentiality impact (C:H), no integrity impact (I:N), and no availability impact (A:N). This means the primary risk is the exposure of sensitive information, such as keystrokes, which could include passwords, personal data, or other confidential inputs. The lack of encryption in data transmission is a fundamental security flaw, exposing users to eavesdropping and data theft if an attacker can position themselves on the communication path. No known exploits are currently reported in the wild, and no patches or fixes have been linked, indicating that users of affected versions remain vulnerable unless mitigations are applied or updates released by the vendor. The vulnerability is particularly concerning in environments where sensitive data entry occurs, such as corporate or governmental settings, as intercepted keystrokes can lead to credential theft or further compromise.

For European organizations, the impact of CVE-2022-45483 can be significant, especially in sectors handling sensitive or regulated data such as finance, healthcare, government, and critical infrastructure. The exposure of keystroke data can lead to credential compromise, unauthorized access, and potential data breaches. Given the vulnerability's nature, attackers could silently capture sensitive inputs without detection, undermining confidentiality. While the vulnerability does not affect data integrity or availability directly, the confidentiality breach alone can have cascading effects, including identity theft, fraud, and espionage. Organizations with remote or local network environments where Lazy Mouse devices are used are at risk, particularly if network segmentation and encryption are not enforced. The medium CVSS score reflects the requirement for the attacker to be in a MitM position, which may limit exploitation to local networks or compromised network segments. However, in environments with weak network security or where attackers can gain network access (e.g., via compromised Wi-Fi), the risk increases. The absence of known exploits suggests limited current active exploitation, but the vulnerability remains a latent risk. Compliance with European data protection regulations (e.g., GDPR) could be impacted if sensitive data is exposed due to this vulnerability, potentially leading to legal and financial consequences.

Implement network-level encryption such as VPNs or secure tunnels (e.g., TLS) to protect communication between Lazy Mouse devices and servers, mitigating the risk of MitM interception. Segment networks to isolate devices using Lazy Mouse from general user or guest networks, reducing attacker access to the communication path. Monitor network traffic for unusual patterns or unauthorized interception attempts, employing intrusion detection/prevention systems (IDS/IPS) capable of detecting MitM activities. Restrict physical and wireless network access to trusted personnel and devices to minimize the risk of attackers gaining a MitM position. Engage with the vendor (thisAAY) to obtain updates or patches addressing this vulnerability; if unavailable, consider discontinuing use of affected versions or replacing the product with alternatives that use encrypted communication. Educate users about the risks of using vulnerable devices on untrusted networks and encourage the use of secure input methods for sensitive data entry. Where possible, implement multi-factor authentication (MFA) to reduce the impact of credential compromise resulting from intercepted keystrokes. Regularly audit and inventory connected devices to identify and remediate use of vulnerable Lazy Mouse versions.
