CVE-2022-37193 is a high-severity vulnerability affecting the Chipolo ONE Bluetooth tracker (2020) and specifically the Chipolo iOS app version 4.13.0. The vulnerability is categorized as Incorrect Access Control (CWE-522), which allows an attacker who has previously obtained access credentials to evade access revocation mechanisms. In practical terms, once a malicious sharee has been granted access to a Chipolo device, they can continue to access the device even after the legitimate owner attempts to revoke their access. This indicates a failure in properly enforcing access control policies within the app or device firmware, allowing unauthorized continued access. The CVSS 3.1 base score is 7.4, reflecting a high severity due to the potential for complete confidentiality and integrity compromise without requiring user interaction or privileges, although the attack complexity is high and the attack vector is network-based (Bluetooth). The vulnerability does not impact availability. No known exploits are currently reported in the wild, and no patches or vendor advisories are listed, suggesting that mitigation may require updates from the vendor or cautious operational controls. This vulnerability highlights risks in Bluetooth device ecosystems where shared access is common, emphasizing the need for robust access revocation and credential management.

For European organizations, the impact of this vulnerability can be significant, especially for those using Chipolo Bluetooth trackers for asset management, personnel tracking, or security purposes. Unauthorized persistent access by malicious actors could lead to theft of location data, unauthorized tracking of personnel or assets, and potential privacy violations under GDPR regulations. The inability to revoke access effectively undermines trust in the device's security model and could expose organizations to espionage or insider threats. Additionally, compromised devices could be used as entry points for lateral movement within corporate environments if integrated with other systems. The confidentiality and integrity of tracking data are at risk, which could affect sectors such as logistics, healthcare, and manufacturing where asset tracking is critical. The lack of availability impact means operational disruption is less likely, but the privacy and security implications remain serious.

To mitigate this vulnerability, European organizations should: 1) Immediately audit and review all shared access permissions on Chipolo devices and revoke any unnecessary or suspicious sharees manually. 2) Avoid sharing access credentials until a vendor patch or update is available. 3) Monitor device usage and access logs for unusual or unauthorized activity. 4) Implement strict operational policies around Bluetooth device sharing and credential management, including multi-factor authentication if supported. 5) Segregate Bluetooth tracking devices from critical network infrastructure to limit potential lateral movement. 6) Engage with the vendor for updates or patches and apply them promptly once available. 7) Consider alternative asset tracking solutions with stronger access control mechanisms if the vulnerability cannot be remediated quickly. 8) Educate users about the risks of sharing device access and enforce least privilege principles.
