CVE-2023-22952 Scanner

SugarCRM is a customer relationship management software used by businesses to manage customer relationships and interactions. Organizations in various sectors like sales, marketing, and customer support implement SugarCRM for improving business operations. Its usage spans from small businesses to large enterprises aiming to optimize workflow and data handling. Many companies favor SugarCRM for its customization capabilities and ability to tailor to specific business needs. The solution aids in engaging customers, enhancing communication, and streamlining internal procedures. As a cloud-based or on-premise platform, it provides flexibility in data management and integration with other tools.

The vulnerability in question is a Remote Code Execution (RCE) flaw. This vulnerability allows attackers to execute arbitrary code on vulnerable systems. The SugarCRM platform, lacking sufficient input validation, is susceptible to this exploit. Malicious actors can craft inputs to inject and execute PHP code, achieving unauthorized actions. Detected in SugarCRM versions before 12.0. Hotfix 91155, this issue exposes systems to significant security risks. This vulnerability enables potential system access and control by unauthorized users if not patched timely.

The vulnerability exists due to missing input validation in the EmailTemplates module within SugarCRM. Exploits can inject malicious PHP code via crafted requests targeting this module. Attackers typically use the `/index.php` endpoint to leverage the code injection flaw. Vulnerable parameters include those associated with file uploads and user authentication actions. The pattern of attack involves posting filenames and actions that trick the system into executing unauthorized PHP scripts. Identifying the executed payload confirms a successful attack, indicating the presence of the vulnerability.

If exploited, this vulnerability can lead to severe consequences for affected systems. Exploiting it could allow attackers to gain unauthorized access to sensitive data or escalate privileges. It's possible to execute code that modifies, deletes, or exfiltrates important data. Additionally, attackers might install backdoors for persistent access or launch further attacks from compromised systems. Such vulnerabilities undermine trust in affected systems and may lead to data breaches, financial loss, or reputational damage. Ensuring systems are patched accordingly is crucial to prevent potential exploits.
