CVE-2025-48739 in TheHive
Summary
by MITRE • 05/23/2025
A Server-Side Request Forgery (SSRF) vulnerability in StrangeBee TheHive 5.2.0 before 5.2.16, 5.3.0 before 5.3.11, 5.4.0 before 5.4.10, and 5.5.0 before 5.5.1 allows remote authenticated attackers with admin permissions (allowing them to access specific API endpoints) to manipulate URLs to direct requests to unexpected hosts or ports. This allows the attacker to use a TheHive server as a proxy to reach internal or otherwise restricted resources. This could be exploited to access other servers on the internal network.

The vulnerability CVE-2025-48739 represents a critical Server-Side Request Forgery flaw within the StrangeBee TheHive platform across multiple versions, specifically affecting releases before the mentioned patched versions. This vulnerability resides in the platform's handling of URL parameters within specific API endpoints, creating a pathway for malicious exploitation that can bypass network segmentation and access internal resources. The flaw fundamentally stems from insufficient input validation and sanitization of user-supplied URL data, allowing attackers to manipulate the application's behavior and redirect requests to unintended destinations. TheHive is a widely used incident response platform designed for security operations teams, making this vulnerability particularly concerning as it provides attackers with a means to extend their reach beyond the initial compromised access point.
The technical implementation of this SSRF vulnerability allows authenticated administrators to leverage specific API endpoints that process URL parameters without proper validation. Attackers can manipulate these parameters to direct the application server to make requests to internal network resources that would normally be inaccessible from the external network. This occurs because the application fails to properly validate or restrict the URLs being processed, enabling the attacker to specify arbitrary hosts or ports that the server will attempt to reach. The vulnerability specifically affects versions 5.2.0 through 5.2.15, 5.3.0 through 5.3.10, 5.4.0 through 5.4.9, and 5.5.0 through 5.5.0, indicating a widespread issue across the platform's version history. According to CWE-918, this vulnerability maps directly to Server-Side Request Forgery, which is classified as a critical security weakness that allows attackers to manipulate the server into making unintended requests.
The operational impact of this vulnerability is severe and multifaceted, as it provides attackers with a sophisticated means to conduct internal reconnaissance and potentially escalate their privileges within the network environment. An attacker with administrative access can leverage this vulnerability to probe internal services, databases, or other sensitive systems that reside behind network firewalls or security boundaries. The platform's role as an incident response tool means that the attacker could potentially access sensitive case data, system configurations, or other internal resources that would normally be protected. This vulnerability also aligns with ATT&CK technique T1566.002, which involves server-side request forgery, and could enable further exploitation through techniques such as internal network scanning and lateral movement. The ability to use the compromised TheHive server as a proxy significantly reduces the attacker's need for direct access to internal systems and can make detection more challenging.
Mitigation strategies for this vulnerability should focus on immediate patching of affected versions to the latest releases that contain the necessary security fixes. Organizations should implement strict input validation and sanitization for all URL parameters processed by the application, ensuring that only expected and safe URLs are accepted. Network segmentation and firewall rules should be enforced to limit the server's ability to communicate with internal resources, even if the vulnerability is exploited. Additionally, implementing API endpoint monitoring and logging can help detect suspicious request patterns that may indicate exploitation attempts. Security teams should also consider implementing web application firewalls to filter potentially malicious requests and establish network access controls that restrict outbound connections from the TheHive server to only necessary internal resources. The vulnerability's classification under CWE-918 and its alignment with ATT&CK techniques emphasize the need for comprehensive security measures that address both the immediate technical flaw and broader network security posture to prevent exploitation and maintain the integrity of the security operations environment.
