CVE-2024-50618 is a security vulnerability identified in the Authentication component of CIPPlanner CIPAce software versions prior to 9.17. The vulnerability arises from the use of single-factor authentication for internal accounts, which allows attackers who obtain the secret (e.g., password or token) associated with these accounts to bypass the intended protection mechanisms. Essentially, if the system is configured to permit login via internal accounts using only one authentication factor, an attacker who compromises this secret can gain full authentication privileges, effectively bypassing any additional security controls that might otherwise be in place. This vulnerability highlights a fundamental weakness in relying solely on single-factor authentication, especially in environments where internal accounts have elevated privileges or access to sensitive functions. Although no known exploits are currently reported in the wild, the risk remains significant because the attack vector depends on secret compromise, which can occur through phishing, insider threats, or other credential theft methods. The lack of a CVSS score indicates that the vulnerability is newly published and not yet fully assessed, but the potential impact on confidentiality, integrity, and availability is considerable. CIPPlanner CIPAce is typically used in industrial planning and critical infrastructure contexts, making the vulnerability particularly relevant for organizations managing such environments. The absence of patch links suggests that a fix may not yet be publicly available, emphasizing the need for immediate mitigations and monitoring.

For European organizations, especially those in critical infrastructure, manufacturing, and industrial planning sectors, this vulnerability could lead to unauthorized access to sensitive systems and data. Attackers exploiting this flaw could gain full authentication rights, potentially allowing them to manipulate planning data, disrupt operations, or exfiltrate confidential information. The impact on confidentiality is high due to possible data exposure; integrity is at risk because attackers could alter critical planning information; and availability could be affected if attackers disrupt system operations. The reliance on single-factor authentication increases the risk of compromise, particularly in environments where internal accounts have broad privileges. This vulnerability could also undermine trust in industrial control systems and planning software, leading to operational delays and financial losses. European organizations with less mature identity and access management practices may be more vulnerable, and the lack of multi-factor authentication enforcement exacerbates the risk. Additionally, regulatory compliance issues may arise if sensitive data is exposed or systems are compromised due to inadequate authentication controls.

1. Immediately review and disable single-factor authentication for internal accounts in CIPPlanner CIPAce configurations where possible. 2. Enforce multi-factor authentication (MFA) for all internal and privileged accounts to add an additional layer of security beyond the compromised secret. 3. Implement strict access controls and least privilege principles to limit the scope of internal accounts and reduce potential damage from compromise. 4. Monitor authentication logs for unusual login attempts or patterns indicative of credential compromise, such as multiple failed attempts or logins from unexpected locations. 5. Segment networks to isolate CIPPlanner CIPAce systems from broader enterprise networks, reducing the attack surface. 6. Educate users and administrators on phishing and credential theft risks to minimize secret compromise. 7. Stay alert for vendor patches or updates addressing this vulnerability and apply them promptly once available. 8. Consider deploying endpoint detection and response (EDR) tools to detect suspicious activities related to authentication bypass attempts. 9. Conduct regular security audits and penetration tests focusing on authentication mechanisms within CIPPlanner CIPAce environments. 10. Maintain an incident response plan tailored to authentication compromise scenarios to enable rapid containment and remediation.
