CVE-2024-46366 in Krayin CRM
Summary
by MITRE • 09/27/2024
A Client-side Template Injection (CSTI) vulnerability in Webkul Krayin CRM 1.3.0 allows remote attackers to execute arbitrary client-side template code by injecting a malicious payload during the lead creation process. This can lead to privilege escalation when the payload is executed, granting the attacker elevated permissions within the CRM system.

The vulnerability CVE-2024-46366 represents a critical client-side template injection flaw in Webkul Krayin CRM version 1.3.0 that fundamentally compromises the application's security model. This issue arises from insufficient input validation and sanitization during the lead creation process, where user-supplied data is directly incorporated into client-side templates without proper escaping or encoding mechanisms. The vulnerability classifies under CWE-79 as a client-side cross-site scripting issue, but extends beyond typical XSS scenarios by enabling full template code execution. Attackers can craft malicious payloads that, when processed by the client-side template engine, execute arbitrary JavaScript code within the context of authenticated users. This creates a dangerous attack surface where legitimate user sessions become compromised, allowing threat actors to manipulate the application behavior and potentially escalate privileges.
The technical exploitation of this vulnerability occurs when an attacker submits crafted input during lead creation that contains malicious template syntax or JavaScript code. The application fails to properly sanitize this input before rendering it within client-side templates, enabling the execution of arbitrary code in the victim's browser context. This type of injection can leverage various template engines such as Handlebars, Mustache, or similar frameworks that support dynamic template rendering. The attack vector is particularly dangerous because it operates entirely on the client-side, making it difficult to detect through traditional server-side security controls. The vulnerability's impact extends beyond simple data theft or session hijacking, as successful exploitation can lead to privilege escalation within the CRM system, potentially allowing attackers to gain administrative access or perform unauthorized operations.
The operational consequences of CVE-2024-46366 are severe for organizations using Webkul Krayin CRM, as it provides attackers with a powerful foothold for lateral movement and persistent access within the system. When executed successfully, the injected code can intercept user credentials, modify CRM data, create new user accounts, or even establish backdoor access for continued exploitation. The vulnerability affects the core business processes of CRM systems, potentially compromising sensitive customer information, sales data, and business intelligence. Organizations may face regulatory compliance issues and significant financial losses due to data breaches resulting from this vulnerability. The attack can be executed remotely without requiring any special privileges or access to the server infrastructure, making it particularly attractive to threat actors seeking to exploit enterprise applications at scale.
Mitigation strategies for CVE-2024-46366 must address both the immediate vulnerability and implement comprehensive security controls to prevent similar issues. Organizations should immediately upgrade to the latest version of Webkul Krayin CRM where the vulnerability has been patched, as this represents the most effective remediation approach. Additionally, implementing proper input validation and output encoding mechanisms can prevent template injection attacks by ensuring all user-supplied data is properly escaped before being processed by client-side template engines. The principle of least privilege should be enforced through proper access controls and session management, limiting the damage that can be caused by successful exploitation. Network segmentation and monitoring solutions can help detect anomalous behavior patterns that may indicate exploitation attempts. Security teams should also consider implementing Content Security Policy headers to restrict the execution of inline scripts and prevent the execution of unauthorized code. Regular security assessments and penetration testing should be conducted to identify and remediate similar vulnerabilities in other applications within the organization's attack surface. The vulnerability aligns with ATT&CK technique T1059.007 for Command and Scripting Interpreter and T1548.005 for Abuse of Functionality, highlighting the need for comprehensive defensive measures across multiple security domains.
