CVE-2025-25034 Scanner

SugarCRM is a widely adopted customer relationship management (CRM) platform used by organizations to manage sales, marketing, and customer support interactions. It is deployed by businesses ranging from small startups to large enterprises to centralize customer data, automate workflows, and enhance client engagement. The software's flexibility and extensive customization options make it a critical tool for driving revenue and improving customer retention.

The vulnerability CVE-2025-25034 is a critical Remote Code Execution (RCE) flaw stemming from improper validation of PHP serialized input in the SugarRestSerialize.php script. This issue arises when the application unserializes user-supplied data without adequate sanitization, allowing attackers to inject malicious PHP objects. The root cause is the lack of type checking and whitelisting for serialized payloads, which enables arbitrary code execution.

Specifically, the vulnerable endpoint is the SugarRest API's serialization handler, which processes POST requests containing serialized PHP data. The parameter 'data' in the request body is passed directly to the unserialize() function without validation. An attacker can craft a payload that instantiates arbitrary PHP classes, leading to code execution via magic methods like __destruct or __wakeup.

If exploited, an unauthenticated attacker can execute arbitrary commands on the server, potentially gaining full control over the SugarCRM instance. This could lead to data breaches, theft of sensitive customer information, and further lateral movement within the network. The high CVSS score of 9.3 underscores the severity and ease of exploitation.
