CVE-2026-108046 in ALO Suite
Summary
by MITRE • 11/03/2026
Direct Object Reference (IDOR) vulnerability in Alosuite due to insufficient authorization checks when processing object identifiers. By modifying the identifier provided to the ‘/Companies/Edit/{id}’ endpoint, an attacker can access information associated with other companies or users without the appropriate authorization. The vulnerability allows unauthenticated remote attackers to enumerate valid object identifiers and retrieve information that should be restricted to authorized users, resulting in the unauthorized disclosure of application data.

The identified security flaw represents a classic Broken Access Control issue, specifically categorized under CWE-639 as an Insecure Direct Object Reference vulnerability within the Alosuite application ecosystem. This type of vulnerability arises when an application exposes internal implementation objects, such as database keys or file names, directly to users without performing adequate authorization checks on those identifiers. In this specific instance, the flaw is located in the endpoint responsible for editing company details, identified by the path /Companies/Edit/{id}. The core technical deficiency lies in the server-side logic which fails to validate whether the authenticated user requesting access to a specific resource actually owns that resource or possesses administrative privileges over it. Instead of verifying the relationship between the session identity and the requested object identifier, the application blindly trusts the input provided by the client side, allowing any actor who can reach this endpoint to manipulate the id parameter.
From an operational perspective, this vulnerability enables unauthenticated remote attackers to perform vertical privilege escalation in terms of data access, even if they do not have valid credentials for every target entity. By systematically iterating through sequential or predictable integer values assigned as object identifiers, an attacker can enumerate all existing companies and their associated sensitive information stored within the database. This process constitutes a form of automated enumeration that bypasses standard authentication mechanisms entirely. The impact is severe because it leads to the unauthorized disclosure of proprietary business data, potentially including financial records, contact details for employees or clients, internal operational metrics, and other confidential attributes protected by privacy regulations such as GDPR or HIPAA depending on the industry sector.
The attack vector aligns with several techniques documented in the MITRE ATT&CK framework. Specifically, it relates to T1078 Valid Accounts if the attacker uses stolen credentials for some entities but accesses others, though more critically it maps to T1592 Gather Victim Host Information or T1615 Object Discovery when enumerating identifiers. Furthermore, since the vulnerability allows access to restricted data without proper authorization checks, it falls squarely under the ATT&CK technique T1078 Valid Accounts if combined with credential stuffing, but primarily represents a failure in Access Control logic which is often exploited via T1190 Exploit Public-Facing Application. The lack of server-side validation means that client-side security controls are easily bypassed using simple HTTP request manipulation tools or automated scripts, making this vulnerability highly exploitable by low-skilled threat actors as well as sophisticated adversaries seeking to exfiltrate large volumes of data for competitive advantage or ransomware preparation.
To mitigate this vulnerability, the development team must implement robust server-side authorization checks that verify the relationship between the current user session and the requested resource identifier before processing any requests. This involves ensuring that every access control decision is made based on secure system state rather than client-supplied input. Additionally, implementing random or non-sequential identifiers for internal objects can significantly reduce the efficiency of enumeration attacks by making it computationally expensive to guess valid IDs. It is also recommended to enforce strict role-based access controls where only users with specific permissions can view or edit company data belonging to other entities. Regular security testing using dynamic application security scanning tools and manual penetration tests focusing on broken object level authorization will help identify similar flaws across the entire application surface before they can be exploited in production environments.
