CVE-2025-49191 is a medium-severity vulnerability affecting all versions of SICK AG's SICK Field Analytics product. The vulnerability arises from improper restriction of rendered UI layers or frames (CWE-1021) during the creation of iFrame widgets and dashboards. Specifically, when users create dashboards or iFrame widgets, linked URLs are embedded as iFrames without sufficient validation or sanitization. This flaw enables an authorized attacker—someone with permission to create new dashboards or iFrame widgets—to embed malicious code within these iFrames. When other users access the compromised dashboards, the malicious code executes in their browsers, potentially leading to unauthorized actions such as session hijacking, credential theft, or further client-side attacks. The attack requires that the attacker be authenticated with privileges to create dashboards or widgets, and user interaction is necessary to trigger the malicious code execution (i.e., the victim must access the compromised dashboard). The vulnerability has a CVSS 3.1 base score of 4.8, reflecting network attack vector, low attack complexity, high privileges required, user interaction required, and partial impact on confidentiality and integrity but no impact on availability. No known exploits are currently reported in the wild, and no patches have been released yet. The vulnerability affects all versions of the product, indicating a need for immediate mitigation and monitoring until a fix is available.

For European organizations using SICK Field Analytics, this vulnerability poses a risk primarily to the confidentiality and integrity of data accessed through the dashboards. Since the product is used for industrial analytics, often in manufacturing, logistics, or process monitoring, unauthorized code execution could lead to exposure of sensitive operational data or manipulation of displayed information. This could undermine decision-making processes or leak proprietary information. The requirement for attacker authorization to create dashboards limits the attack surface to insider threats or compromised accounts with elevated privileges. However, if exploited, the vulnerability could facilitate lateral movement within the organization or enable targeted phishing attacks by injecting malicious content into dashboards viewed by multiple users. The lack of impact on availability reduces the risk of operational downtime, but the potential for data leakage and integrity compromise remains significant. European organizations with critical infrastructure or manufacturing operations relying on SICK Field Analytics should consider this vulnerability a moderate risk that requires prompt attention to prevent escalation.

1. Restrict dashboard and iFrame widget creation privileges strictly to trusted and trained personnel to minimize the risk of malicious dashboard creation. 2. Implement strong authentication and authorization controls, including multi-factor authentication (MFA) for users with dashboard creation rights, to reduce the risk of account compromise. 3. Monitor user activity logs for unusual dashboard or widget creation patterns that could indicate exploitation attempts. 4. Employ Content Security Policy (CSP) headers on dashboards to restrict the execution of unauthorized scripts and limit the impact of malicious iFrame content. 5. Educate users to avoid interacting with suspicious or unexpected dashboards, especially those created recently or by unfamiliar users. 6. Until an official patch is released, consider disabling the ability to create or embed iFrame widgets if feasible, or isolate the analytics environment from sensitive networks. 7. Regularly check for vendor updates or advisories from SICK AG and apply patches promptly once available. 8. Conduct internal security reviews and penetration tests focusing on dashboard creation and embedding functionalities to identify and remediate similar weaknesses.
