CVE-2022-24190: n/a in n/a
The /device/acceptBind end-point for Ourphoto App version 1.4.1 does not require authentication or authorization. The user_token header is not implemented or present on this end-point. An attacker can send a request to bind their account to any users picture frame, then send a POST request to accept their own bind request, without the end-users approval or interaction.
AI Analysis
Technical Summary
CVE-2022-24190 is a high-severity vulnerability affecting the Ourphoto App version 1.4.1. The vulnerability resides in the /device/acceptBind endpoint, which is designed to manage the binding process between user accounts and digital picture frames. Critically, this endpoint does not require any form of authentication or authorization, and the user_token header—normally used to verify the identity and permissions of the requester—is absent from this endpoint. This lack of access control allows an attacker to send a request to bind their own account to any victim's picture frame without the victim's consent or interaction. Subsequently, the attacker can send a POST request to accept their own bind request, effectively gaining control over the victim's device or account linkage. The vulnerability is classified under CWE-306 (Missing Authentication for Critical Function) and CWE-862 (Missing Authorization), highlighting the absence of proper security checks. The CVSS v3.1 base score is 7.5, indicating a high severity level, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), no impact on confidentiality (C:N), high impact on integrity (I:H), and no impact on availability (A:N). This means an unauthenticated attacker can remotely exploit this vulnerability to alter the integrity of user bindings without affecting confidentiality or availability. No known exploits have been reported in the wild as of the publication date (November 28, 2022), and no patches or vendor project details are provided, suggesting the product may be niche or less widely tracked. The vulnerability primarily threatens the integrity of user-device relationships, potentially allowing attackers to manipulate or hijack picture frame bindings, which could lead to unauthorized content display or privacy violations.
Potential Impact
For European organizations, especially those involved in consumer electronics retail, digital photo frame distribution, or IoT device management, this vulnerability poses a significant risk. Unauthorized binding of attacker accounts to user devices can lead to manipulation of displayed content, potentially exposing users to malicious or inappropriate images, misinformation, or phishing attempts via the device interface. While confidentiality is not directly impacted, the integrity compromise can erode user trust and brand reputation. Organizations managing large deployments of Ourphoto App or similar IoT devices could face operational disruptions if attackers exploit this flaw at scale. Additionally, privacy regulations such as GDPR in Europe could impose penalties if personal data or user consent mechanisms are circumvented due to this vulnerability. The lack of authentication also means attackers can exploit this remotely without needing physical access or user interaction, increasing the attack surface. The threat is particularly relevant for sectors with high consumer engagement in smart home devices, including retail chains, hospitality, and digital service providers integrating such devices into their offerings.
Mitigation Recommendations
Given the absence of vendor patches, European organizations should implement compensating controls immediately. First, network-level restrictions should be applied to limit access to the /device/acceptBind endpoint, such as firewall rules or API gateways enforcing authentication and authorization checks. Organizations should monitor network traffic for unusual POST requests to this endpoint and implement anomaly detection to flag suspicious binding activities. If possible, disable or restrict the use of the affected version of the Ourphoto App until a patch or update is available. For managed devices, enforce device-level access controls and consider isolating picture frames on segmented networks to reduce exposure. User education campaigns should inform customers about the risks of unauthorized device bindings and encourage vigilance. Additionally, organizations should engage with the vendor or community to seek updates or patches and participate in responsible disclosure programs to accelerate remediation. Logging and auditing of binding requests should be enhanced to enable forensic analysis in case of exploitation. Finally, integrating multi-factor authentication or token validation mechanisms at the application layer would mitigate unauthorized access if the vendor releases updates.
