CVE-2025-55007 in Knowage-Server
Summary
by MITRE • 09/01/2025
Knowage is an open source analytics and business intelligence suite. Prior to version 8.1.37, Knowage is vulnerable to server-side request forgery. The vulnerability allows attackers to send requests to arbitrary hosts/paths. Since the attacker is not able to read the response, the impact of this vulnerability is limited. However, an attacker could be able to leverage this vulnerability to scan the internal network. This issue has been patched in version 8.1.37.

The CVE-2025-55007 vulnerability affects Knowage, an open source analytics and business intelligence suite that provides organizations with data visualization, reporting, and dashboard capabilities. This vulnerability represents a significant security weakness in the software's request handling mechanisms, specifically within its server-side processing functions. The flaw exists in versions prior to 8.1.37, indicating that the software development team identified and addressed this issue through a targeted patch release. The vulnerability's presence in the analytics platform raises concerns about potential exposure of internal network infrastructure during routine business intelligence operations.
The technical implementation of this vulnerability stems from insufficient input validation and sanitization within the Knowage application's request processing pipeline. Attackers can exploit this weakness by crafting malicious requests that force the application to make outbound connections to arbitrary network destinations. This type of vulnerability maps directly to CWE-918, which describes server-side request forgery vulnerabilities where applications process untrusted input to make network requests. The flaw essentially allows attackers to manipulate the application's network behavior without proper authorization, creating a pathway for unauthorized communication with internal systems.
The operational impact of this vulnerability, while limited compared to other SSRF variants, remains substantial for enterprise environments. Although attackers cannot directly read response data from the forged requests, they can leverage this capability to perform network reconnaissance activities against internal systems. This reconnaissance capability enables attackers to map internal network topology, identify active services, and potentially discover vulnerable internal hosts that may not be directly exposed to external networks. The vulnerability essentially transforms the Knowage platform into a potential reconnaissance tool for attackers seeking to understand internal network structures. This aligns with ATT&CK technique T1018, which covers discovery of network endpoints and T1046, which covers network service scanning.
Organizations utilizing Knowage versions prior to 8.1.37 should prioritize immediate patch deployment to mitigate this vulnerability. The remediation approach involves upgrading to version 8.1.37 or later, which contains the necessary code changes to properly validate and sanitize all external request parameters. Network administrators should also implement additional monitoring measures to detect unusual outbound network activity that might indicate exploitation attempts. Security teams should review application logs for any suspicious outbound requests and consider implementing network segmentation to limit the potential impact of successful exploitation attempts. The patch addresses the core issue by strengthening input validation mechanisms and ensuring that all external request destinations are properly verified against a trusted whitelist of acceptable endpoints.
