CVE-2024-50620 is a security vulnerability identified in CIPPlanner CIPAce, a project and document management software, affecting versions prior to 9.17. The flaw resides in the unrestricted upload functionality within the rich text editor and document management components, where authorized users can upload files with dangerous types, specifically executable files. Normally, file upload controls restrict executable content to prevent malicious code execution. However, in this case, the software fails to properly validate or restrict file types during image insertion in the rich text editor and during file uploads on the document management page. If these executable files are stored in directories with execution permissions or outside shared directories that restrict execution, an attacker could execute arbitrary code on the server hosting CIPPlanner CIPAce. This could lead to unauthorized system access, data compromise, or further network penetration. The vulnerability requires the attacker to be an authenticated user, which limits exploitation to insiders or compromised accounts. No public exploits have been reported yet, and no official CVSS score has been assigned. The lack of patch links suggests that remediation may require vendor intervention or configuration changes. The vulnerability highlights the importance of strict file validation, secure storage practices, and least privilege principles in web application design.

For European organizations, the impact of CVE-2024-50620 can be significant, particularly for those using CIPPlanner CIPAce in critical project management or document handling workflows. Successful exploitation could allow attackers to execute arbitrary code on servers, potentially leading to data breaches, disruption of business operations, or lateral movement within the network. Confidentiality could be compromised if sensitive project or document data is accessed or exfiltrated. Integrity and availability of the system could also be affected if malicious payloads modify or delete data or disrupt service availability. The requirement for authentication reduces the risk from external attackers but raises concerns about insider threats or compromised credentials. Organizations in sectors such as manufacturing, engineering, or public infrastructure that rely on CIPPlanner CIPAce may face operational disruptions and reputational damage. Additionally, regulatory compliance risks arise if personal or sensitive data is exposed due to this vulnerability.

To mitigate CVE-2024-50620, organizations should implement the following specific measures: 1) Immediately restrict file upload types in CIPPlanner CIPAce to exclude executable formats such as .exe, .bat, .cmd, .sh, and script files, especially in the rich text editor and document management components. 2) Configure the storage directories to disallow execution permissions, ensuring uploaded files cannot be run as executables regardless of their type. 3) Apply the latest patches or updates from the CIPPlanner vendor as soon as they become available. 4) Enforce strict authentication and access controls to limit upload capabilities to trusted users only. 5) Monitor file upload logs and server activity for unusual or unauthorized executable file uploads. 6) Conduct regular security audits and penetration testing focused on file upload functionalities. 7) Educate users about the risks of uploading unauthorized file types and implement multi-factor authentication to reduce the risk of account compromise. 8) If immediate patching is not possible, consider isolating the CIPPlanner server in a segmented network zone with limited access to critical infrastructure.
