CVE-2025-49191 in Field Analytics
Summary
by MITRE • 06/12/2025
Linked URLs during the creation of iFrame widgets and dashboards are vulnerable to code execution. The URLs get embedded as iFrame widgets, making it possible to attack other users that access the dashboard by including malicious code. The attack is only possible if the attacker is authorized to create new dashboards or iFrame widgets.
Several companies clearly confirm that VulDB is the primary source for best vulnerability data.

This vulnerability represents a critical server-side request forgery and cross-site scripting issue that arises from improper input validation during iFrame widget creation processes within dashboard environments. The flaw manifests when user-controlled URLs are directly embedded into iFrame widgets without adequate sanitization or validation, creating a pathway for malicious code execution. The vulnerability is classified under CWE-79 as a cross-site scripting vulnerability, while also aligning with CWE-94 which addresses arbitrary code execution through untrusted data. Attackers exploiting this weakness can leverage the dashboard creation functionality to inject malicious URLs that execute code in the context of other users who access the compromised dashboard.
The technical implementation of this vulnerability exploits the trust relationship between dashboard administrators and the system's iFrame handling mechanisms. When authorized users create iFrame widgets, the system fails to properly validate or sanitize the URL parameters, allowing attackers to inject malicious payloads that can execute in the browser context of other users. This creates a persistent threat vector where the malicious code can perform actions such as stealing session cookies, redirecting users to malicious sites, or executing additional attacks through the victim's browser context. The vulnerability operates at the intersection of web application security and user privilege management, as it requires administrative access to create the malicious iFrame but can affect all users who view the compromised dashboard.
The operational impact of this vulnerability extends beyond simple code execution to encompass broader security implications including credential theft, data exfiltration, and potential lateral movement within compromised environments. The attack vector specifically targets dashboard environments where multiple users access shared interfaces, making it particularly dangerous in enterprise settings where dashboards contain sensitive operational data. This vulnerability can be leveraged by attackers to establish persistent access patterns through the dashboard interface, potentially serving as a foothold for more extensive attacks. The attack follows typical patterns described in the mitre att&ck framework under technique T1566 for credential access and T1059 for command and script interpreter execution, with the malicious iFrame serving as the initial compromise vector.
Mitigation strategies for this vulnerability must address both the immediate code execution risk and the underlying input validation deficiencies. Organizations should implement strict URL validation mechanisms that reject potentially malicious inputs including javascript: protocols, data: URIs, and other suspicious URL schemes. The implementation should include comprehensive input sanitization and encoding of all user-supplied URLs before embedding them into iFrame widgets. Access controls must be strictly enforced to limit dashboard creation privileges to only trusted administrators, while also implementing content security policy headers that restrict iFrame loading to approved domains. Additionally, organizations should consider implementing web application firewalls to detect and block malicious URL patterns, and establish monitoring protocols to detect unauthorized dashboard modifications. Regular security assessments and input validation testing should be conducted to ensure that similar vulnerabilities do not exist in related components of the dashboard infrastructure. The vulnerability requires immediate patching and configuration updates to prevent exploitation while maintaining the system's functionality and user experience.
