Summary
by MITRE • 05/22/2023
Incorrect Permission Assignment for Critical Resource Vulnerability in Apache Software Foundation Apache InLong.This issue affects Apache InLong: from 1.2.0 through 1.6.0. The attacker can delete others' subscriptions, even if they are not the owner of the deleted subscription. Users are advised to upgrade to Apache InLong's 1.7.0 or cherry-pick [1] to solve it.

The CVE-2023-31453 vulnerability represents a critical authorization flaw within the Apache InLong platform, specifically targeting the permission assignment mechanism for essential system resources. This vulnerability exists in Apache InLong versions ranging from 1.2.0 through 1.6.0, creating a significant security risk that allows unauthorized users to manipulate subscription resources that belong to other users. The flaw fundamentally undermines the integrity of the access control system by permitting attackers to delete subscriptions without proper authentication or authorization, effectively bypassing the intended ownership restrictions that should protect user data and system resources.
The technical nature of this vulnerability stems from improper validation of user permissions when processing subscription deletion requests. When an attacker submits a deletion request for a subscription, the system fails to adequately verify whether the requesting user possesses the necessary privileges to perform this action. This misconfiguration creates a path for privilege escalation where any authenticated user can target and remove subscriptions owned by other users, effectively enabling unauthorized data manipulation and potential disruption of legitimate system operations. The vulnerability operates at the application level, specifically within the resource management and access control components that handle subscription lifecycle operations.
From an operational impact perspective, this vulnerability poses severe risks to organizations relying on Apache InLong for data processing and streaming operations. The ability to delete subscriptions without proper authorization creates opportunities for both accidental and intentional data loss, as subscribers may lose access to their data streams and processing pipelines. Attackers could exploit this flaw to disrupt service availability, interfere with business operations, or potentially gain insights into the system's usage patterns by removing specific subscription data. The vulnerability particularly impacts multi-tenant environments where multiple users or organizations share the same InLong instance, as it allows cross-user interference and potential data integrity violations.
The recommended mitigation strategy involves upgrading to Apache InLong version 1.7.0, which includes the necessary security patches to address the permission assignment flaw. Organizations unable to immediately upgrade should implement the cherry-pick solution referenced in the advisory, specifically the changes outlined in pull request #7949 from the Apache InLong repository. This patch implements proper permission validation checks that ensure users can only perform subscription deletion operations on resources they own or have explicit authorization to modify. The fix aligns with security best practices for access control and follows the principle of least privilege, ensuring that system operations require appropriate authentication and authorization before execution. Organizations should also conduct thorough security assessments to identify any potential exploitation attempts and implement monitoring for unauthorized subscription deletion activities.
This vulnerability maps to CWE-284, which describes improper access control issues in software systems, and aligns with ATT&CK technique T1078 for valid accounts and privilege escalation. The flaw represents a classic case of insufficient authorization checks that allows attackers to perform operations beyond their intended permissions. The impact extends beyond immediate data loss to include potential service disruption, compliance violations, and damage to system integrity. Organizations should implement comprehensive monitoring solutions to detect unauthorized access attempts and establish incident response procedures specifically addressing access control violations. The vulnerability underscores the critical importance of proper authorization mechanisms in distributed data processing systems where multiple users interact with shared resources and highlights the need for regular security assessments of enterprise data platforms.
