The vulnerability identified as CVE-2019-14221 affects 1CRM On-Premise Software version 8.5.7, representing a cross-site scripting flaw that can be exploited by malicious actors to execute arbitrary code within the context of a victim's browser session. This issue manifests specifically during the Run Report operation, where input validation mechanisms fail to properly sanitize user-supplied data, creating an attack vector that can be leveraged for unauthorized access and data manipulation.
The technical flaw stems from inadequate input sanitization within the report execution functionality of the 1CRM application. When users submit report parameters or data through the interface, the system fails to adequately filter or escape special characters that could be interpreted as HTML or JavaScript code. This vulnerability falls under the CWE-79 category of Cross-Site Scripting, specifically representing a reflected XSS attack where malicious payloads are injected into the application's response and subsequently executed in the victim's browser. The flaw demonstrates poor security practices in data handling and input validation that violates fundamental web application security principles.
The operational impact of this vulnerability extends beyond simple script execution, potentially enabling attackers to perform session hijacking, steal sensitive user credentials, manipulate data within the CRM system, or redirect users to malicious websites. An attacker could craft a malicious report request containing JavaScript payloads that would execute when another user views the report results, effectively creating a persistent threat vector within the organization's internal systems. This vulnerability particularly threatens organizations that rely heavily on 1CRM for customer relationship management, as it could lead to unauthorized access to sensitive customer data, financial information, and business-critical records.
Mitigation strategies for CVE-2019-14221 should include immediate implementation of proper input validation and output encoding mechanisms within the report generation functionality. Organizations should deploy web application firewalls to filter malicious payloads and implement content security policies to restrict script execution. The vendor should provide a security patch that properly sanitizes user inputs during report operations and enforces strict validation of all parameters passed to the reporting engine. Additionally, security awareness training for administrators and users should emphasize the dangers of executing reports from untrusted sources, while regular security audits should be conducted to identify similar vulnerabilities in other application components. This vulnerability aligns with ATT&CK technique T1566.001 for initial access through malicious web content and demonstrates the importance of implementing defense-in-depth strategies to protect against client-side attacks.
