CVE-2024-50619 is a security vulnerability identified in the My Account and User Management components of CIPPlanner CIPAce software versions prior to 9.17. The vulnerability allows a low-privileged authenticated user to escalate their access rights by manipulating client-side user ID parameters to access other users' accounts and by modifying information related to disabled user roles to elevate their system privileges. Specifically, the flaw arises because the application fails to properly validate user identity and role information on the server side, enabling attackers to tamper with client requests to gain unauthorized access. This vulnerability impacts both confidentiality—by exposing other users' account information—and integrity—by allowing unauthorized privilege changes. Exploitation requires the attacker to be authenticated but does not require additional user interaction, making it a direct threat once credentials are obtained. No CVSS score has been assigned yet, and there are no known exploits in the wild. The vulnerability affects enterprise environments using CIPPlanner CIPAce for user and account management, potentially impacting operational security and data privacy. The lack of patch links suggests that fixes may not yet be publicly available, emphasizing the need for vigilance and interim controls.

For European organizations, this vulnerability poses a significant risk to the confidentiality and integrity of user data managed within CIPPlanner CIPAce. Unauthorized access to other users' accounts can lead to data breaches, exposure of sensitive information, and potential disruption of business processes. Privilege escalation could allow attackers to perform unauthorized administrative actions, potentially leading to further compromise of systems and data. Organizations in sectors such as critical infrastructure, utilities, and manufacturing that rely on CIPPlanner CIPAce for operational planning and user management are particularly vulnerable. The impact extends to regulatory compliance risks under GDPR due to unauthorized data access. Additionally, the ability to escalate privileges without requiring additional user interaction increases the likelihood of successful exploitation once credentials are compromised. This could facilitate lateral movement within networks and increase the attack surface for more damaging intrusions.

To mitigate this vulnerability, European organizations should first verify their use of CIPPlanner CIPAce and identify affected versions prior to 9.17. Until an official patch is released, organizations should implement strict access controls and monitor user activity for anomalous behavior, especially focusing on unusual account access patterns and role modifications. Enforce strong authentication mechanisms and consider multi-factor authentication to reduce the risk of credential compromise. Limit the number of users with privileges to modify roles and audit these changes regularly. Employ network segmentation to isolate critical systems running CIPPlanner CIPAce and restrict access to trusted personnel only. Additionally, validate and sanitize all client-supplied data on the server side to prevent tampering. Prepare to deploy patches promptly once available and conduct thorough testing to ensure the vulnerability is fully remediated. Finally, raise user awareness about the risks of credential theft and encourage secure password practices.
