CVE-2026-121436 in Froxlor
Summary
by MITRE • 11/03/2026
Froxlor from 2.3.8 before 2.3.15 contains an information disclosure vulnerability that allows administrators with customers_see_all to view every account's API key and secret through an unscoped WHERE 1 query in api_keys.php. Attackers can read the super administrator's apikey and secret from the detail modal and replay them to the API to gain super administrator control.

The vulnerability identified in Froxlor versions prior to 2.3.15 represents a critical information disclosure flaw rooted in improper access control mechanisms within the application’s administrative interface. Specifically, the issue resides in the api_keys.php module, which is designed to manage API credentials for various user accounts. The core technical defect involves an unscoped SQL query that utilizes a WHERE clause of 1=1 or similar tautology, effectively bypassing any intended row-level security filters. This architectural oversight allows users possessing the customers_see_all permission level to retrieve database records belonging to all other customer accounts without restriction. Consequently, this flaw transforms what should be an isolated administrative view into a comprehensive data exfiltration vector for privileged insiders or compromised admin accounts with limited scope permissions that still retain broad visibility rights.
From a technical perspective, the exploitation of this vulnerability relies on the attacker leveraging their existing high-level privileges to access the API key management interface. By navigating to the relevant detail modal within the administrative dashboard, an authenticated user can extract sensitive cryptographic material, specifically the API keys and secrets associated with every account in the system. The absence of proper scoping means that the database query does not filter results based on the requesting user’s specific domain or customer ID. This lack of contextual validation allows for the systematic enumeration and extraction of credentials across the entire infrastructure. The retrieved super administrator API key and secret are particularly dangerous as they provide full programmatic access to the control panel, enabling actions such as creating new accounts, modifying DNS records, managing email configurations, and potentially executing further attacks against hosted services without triggering standard administrative audit logs associated with direct UI logins.
The operational impact of this vulnerability is severe, extending beyond simple data leakage into complete system compromise. Once an attacker obtains the super administrator API credentials through this information disclosure channel, they can replay these tokens to interact directly with the Froxlor application programming interface. This capability grants them equivalent privileges to a human super administrator but offers greater stealth and automation potential. The attacker can manipulate server configurations, exfiltrate sensitive customer data stored within associated services, or deploy malicious scripts under the guise of legitimate administrative tasks. Furthermore, because API keys are often used for automated integrations with third-party tools such as DNS providers or email servers, compromising these tokens may lead to secondary compromises in external ecosystems, affecting domain resolution integrity and communication security for all hosted customers.
This vulnerability aligns closely with CWE-200: Information Exposure and CWE-862: Missing Authorization, reflecting a failure to enforce proper access controls on sensitive data resources. In the context of the MITRE ATT&CK framework, this behavior corresponds to T1530: Data from Cloud Storage Object or Database, where an adversary accesses stored information without authorization. It also relates to T1078: Valid Accounts, as the attacker utilizes legitimate but overly privileged credentials to maintain access and escalate their influence within the environment. The scenario highlights a common pitfall in web application development where administrative functions are exposed via API endpoints that do not strictly validate the scope of the requesting user against the data being accessed.
To mitigate this vulnerability, immediate action is required by upgrading Froxlor to version 2.3.15 or later, which addresses the flawed query logic and enforces proper scoping on database operations within the api_keys.php module. Administrators should also review their permission structures to ensure that the customers_see_all privilege does not grant unnecessary access to sensitive credential data unless absolutely required for operational needs. Implementing strict role-based access control principles will help prevent such broad permissions from being assigned inadvertently. Additionally, organizations should rotate all API keys and secrets immediately upon discovering potential exposure, as previous credentials may have already been harvested by malicious actors. Regular security audits focusing on SQL query construction and authorization checks in administrative interfaces are essential to preventing similar flaws in future development cycles.
