CVE-2022-24187 in App
Summary
by MITRE • 11/29/2022
The user_id and device_id on the Ourphoto App version 1.4.1 /device/* end-points both suffer from insecure direct object reference vulnerabilities. Other end-users user_id and device_id values can be enumerated by incrementing or decrementing id numbers. The impact of this vulnerability allows an attacker to discover sensitive information such as end-user email addresses, and their unique frame_token value of all other Ourphoto App end-users.

The CVE-2022-24187 vulnerability represents a critical insecure direct object reference issue within the Ourphoto mobile application version 1.4.1, specifically affecting the /device/* endpoints. This vulnerability stems from inadequate input validation and access control mechanisms that allow unauthorized users to manipulate object references directly through the application programming interface. The flaw exists in how the application handles user_id and device_id parameters, which are exposed without proper authorization checks, creating a pathway for attackers to enumerate valid identifiers through simple numerical incrementation or decrementation techniques.
The technical implementation of this vulnerability falls under CWE-639, which describes insecure direct object reference conditions where applications fail to verify that the user has proper authorization to access specific resources. The vulnerability operates at the application layer and can be exploited through predictable parameter manipulation, allowing attackers to systematically discover valid user identifiers and device references. When an attacker successfully enumerates these identifiers, they gain access to sensitive user information including email addresses and frame_token values, which represent a significant privacy and security risk.
The operational impact of this vulnerability extends beyond simple information disclosure, as the stolen frame_token values could potentially enable further attacks including session hijacking, unauthorized device access, and cross-user data exposure. Attackers can leverage this information to impersonate legitimate users, access personal photo collections, and potentially gain control over connected devices. The vulnerability's exploitation requires minimal technical skill, making it particularly dangerous as it can be automated and scaled across large user bases. The enumeration process typically involves sending multiple requests with incrementally modified identifiers until valid responses are received, indicating successful access to target user accounts.
Mitigation strategies for CVE-2022-24187 should focus on implementing robust access control mechanisms and proper input validation at the application level. The primary remediation involves introducing proper authentication checks for all device endpoints, ensuring that users can only access their own resources or those they are explicitly authorized to access. This includes implementing server-side access control lists, proper session management, and parameter validation that prevents direct object reference manipulation. Additionally, organizations should consider implementing rate limiting and monitoring mechanisms to detect and prevent automated enumeration attempts. The vulnerability also aligns with ATT&CK technique T1078 which covers valid accounts and credential access, as it enables unauthorized access through legitimate user identifiers. Regular security testing and code reviews should be implemented to prevent similar issues in future releases, with particular attention to endpoint validation and access control implementation. The fix requires comprehensive testing to ensure that legitimate user functionality remains intact while preventing unauthorized access patterns.
