CVE-2026-23550 Scanner

Modular DS is an advanced digital management system used for managing websites and related digital assets efficiently. It is popular among businesses and developers who require streamlined processes for handling multiple websites simultaneously. The software is often used by IT departments in organizations where digital presence is critical. Modular DS offers features such as backup, monitoring, and modular connectors to enhance usability. It is especially valued in environments demanding robust website update and monitoring capabilities. The system integrates seamlessly with WordPress as a plugin, augmenting its functionalities with additional tools and controls.

Privilege escalation is a critical vulnerability that occurs when unauthorized users gain elevated access to resources that are typically protected. This type of vulnerability commonly arises due to broken access control mechanisms where incorrect privilege assignments allow attackers to exploit systems. In the context of Modular DS, it means that attackers can escalate their privileges to access sensitive data or perform unauthorized actions. This vulnerability can be particularly damaging as it compromises the security of sensitive information stored or managed by the software. Due diligence is required to ensure that access control mechanisms are robustly implemented to reduce risk.

The vulnerability in Modular DS arises from incorrect privilege assignments allowing attackers to escalate their access. The vulnerable endpoints involve API calls where parameters can be manipulated to gain unauthorized access. Specifically, endpoints such as '/index.php/api/modular-connector/login/' on the WordPress platform are at risk. The vulnerability can be exploited by crafting specific GET requests that bypass normal authentication checks. When successfully exploited, the server responds with a status code of 302, indicating potential unauthorized access due to incorrect configuration. This technical misconfiguration allows malicious actors to impersonate other users or perform actions usually restricted to privileged accounts.

Exploiting this vulnerability can have several detrimental effects on affected systems. Unauthorized users may gain access to blocked functionalities, leading to potential data breaches or modifications. Sensitive information could be disclosed, tampered with, or deleted, disrupting operations and leading to data integrity issues. The organization may face reputational damage and regulatory penalties if customer or sensitive company data is compromised. Furthermore, attackers with escalated privileges might deploy malware or further exploit the system for other vulnerabilities, exacerbating the security situation. Protecting against privilege escalation attacks is vital to maintaining a secure IT infrastructure.
