CVE-2023-22952 Scanner

SugarCRM is a widely used customer relationship management (CRM) software that helps businesses manage sales, marketing, and customer support. Organizations of various sizes use SugarCRM to streamline their workflows and improve customer engagement. The software provides extensive customization options, allowing businesses to tailor it to their needs. SugarCRM is available in both cloud-based and self-hosted versions, making it flexible for different deployment requirements. Due to its extensive use in managing sensitive customer data, security vulnerabilities in SugarCRM can pose significant risks. Ensuring the security of SugarCRM installations is crucial for maintaining data integrity and operational security.

The CVE-2023-22952 vulnerability in SugarCRM is a Remote Code Execution (RCE) flaw that allows attackers to inject arbitrary PHP code into the system. This occurs due to improper input validation in the EmailTemplates module. Attackers can exploit this flaw by sending a specially crafted HTTP request containing malicious code. When executed, this can lead to unauthorized command execution on the server. The vulnerability allows unauthenticated attackers to gain control over the affected system. This can result in data theft, service disruption, or even full system compromise.

The vulnerability is exploited through an HTTP POST request to the /index.php endpoint, using the AttachFiles action within the EmailTemplates module. The attacker uploads a file with embedded PHP code, which is then executed by the server. The request bypasses authentication and injects malicious commands that run with the privileges of the web server. The uploaded file is stored in the cache/images/ directory, from where it can be accessed and executed. The flaw arises from insufficient validation of file inputs, enabling unauthorized uploads. Attackers leverage this weakness to execute arbitrary code remotely.

When exploited, this vulnerability allows attackers to take full control of the SugarCRM instance. Attackers can execute system commands, steal sensitive data, and modify application behavior. Unauthorized access can lead to privilege escalation, enabling attackers to gain administrative control. The compromised system can be used for launching further attacks on the internal network. In severe cases, attackers can deploy backdoors, making it difficult to detect and remove the threat. The impact of exploitation includes financial loss, reputational damage, and legal consequences for affected organizations.
