Kanboard, a project management software utilizing the Kanban methodology, has a medium-severity vulnerability identified as CVE-2025-55011. This vulnerability allows a malicious actor to exploit the createTaskFile method in the API, which fails to validate the task_id parameter and does not check for path traversal. As a result, an attacker could potentially write files to any location on the system that the application user controls. The impact, however, is somewhat limited as the filenames are hashed and lack any file extension.
The vulnerability was discovered prior to version 1.2.47, and it has been patched in this version. With a CVSS score of 6.4, the severity is classified as medium, indicating that organizations should address this in their priority patch cycle.
Risk to organizations includes potential unauthorized file creation, which could lead to data exposure or system compromise if not addressed. While there is currently no confirmed public exploit, the nature of this vulnerability necessitates immediate attention to safeguard against its potential misuse.
Organizations using Kanboard should prioritize patching immediately to mitigate the risks associated with this vulnerability.
Vulnerability Details
CVE-2025-55011 affects Kanboard versions prior to 1.2.47. The vulnerability arises from a lack of validation in the createTaskFile method of the API, specifically regarding the task_id parameter and path traversal checks. The CVSS score varies, with a primary score of 5.3 from NVD and a secondary score of 6.4 from GitHub. The CWE classification for this vulnerability is CWE-22, indicating improper limitation of a pathname to a restricted directory.
Technical Analysis
Root cause analysis reveals that the createTaskFile method does not verify the validity of the task_id parameter. As a consequence, an attacker can utilize this oversight to execute path traversal attacks, allowing file creation in arbitrary locations within the server. The attack vector is network-based, requiring low complexity and minimal privileges, making it relatively easy for attackers to exploit if they can send requests to the API.
The attack complexity is low, meaning that no special conditions need to be met for the exploitation to succeed. No user interaction is necessary, and the impact on confidentiality and integrity is classified as low, while availability is not impacted.
Risk & Impact Analysis
The deployment of this vulnerability in real-world scenarios poses a significant risk to organizations utilizing Kanboard. The potential for malicious actors to write files on the server could lead to unauthorized access or data leaks, especially in environments where sensitive information is handled. Organizations should be wary of the implications, particularly in cases where the application is publicly accessible.
The urgency for organizations to respond is underscored by the CVSS score of 6.4, indicating a medium-level threat. Given the exploitability and potential impact, it is advisable to schedule remediation in the next patch cycle, ensuring that any potential for exploitation is mitigated.
In summary, organizations using Kanboard must take proactive measures to patch the vulnerability, ensuring that their systems remain secure against possible attacks.
