CVE-2024-52311 identifies an incorrect authorization vulnerability (CWE-863) in Amazon's data.all product version 1.0.0. The core issue lies in the handling of authentication tokens issued through Amazon Cognito: these tokens are not invalidated or revoked when a user logs out. Consequently, the tokens remain valid until their expiration time, allowing a previously authenticated user or potentially an attacker with access to the token to continue executing authorized API requests. This behavior violates the principle of session termination and can lead to unauthorized access to sensitive data or operations within data.all. The vulnerability has a CVSS 4.0 base score of 5.3, indicating a medium severity level, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:L), and no user interaction (UI:N). The impact affects confidentiality, integrity, and availability to a limited extent (VC:L, VI:L, VA:L). No patches or known exploits are currently available, but the flaw represents a significant risk in environments where token management is critical. The vulnerability is particularly relevant for organizations relying on data.all for data processing and API interactions, as it undermines secure session management practices.

For European organizations, this vulnerability could lead to unauthorized access to sensitive data and API functions within the data.all environment if tokens are intercepted or if users fail to properly log out. Since tokens remain valid post-logout, attackers or malicious insiders could exploit this to maintain persistent access without re-authentication, increasing the risk of data breaches and unauthorized data manipulation. This could affect compliance with GDPR and other data protection regulations, as unauthorized data access may lead to personal data exposure. The medium severity rating suggests moderate risk, but the impact could be amplified in sectors with high data sensitivity such as finance, healthcare, and government. Additionally, prolonged token validity could facilitate lateral movement within cloud environments, complicating incident response efforts.

Organizations should implement immediate measures to mitigate this vulnerability by enforcing token revocation or invalidation upon user logout within their data.all deployments. This may require configuration changes or updates to the authentication flow to explicitly revoke Cognito tokens. Additionally, reducing token lifetime and implementing refresh token rotation can limit the window of exposure. Monitoring and logging API usage to detect anomalous or unexpected token activity is critical for early detection of exploitation attempts. Where possible, multi-factor authentication (MFA) should be enforced to reduce the risk of token compromise. Organizations should also stay alert for official patches or updates from Amazon and apply them promptly once available. Finally, educating users on proper logout procedures and session management can help reduce risks associated with token persistence.
