Threat & Defense at a Glance

What attackers do: exploitation maps to Exploitation for Privilege Escalation (T1068) and 2 other techniques. What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

AC-3 Access Enforcement good match

prevent

AC-3 requires enforcement of approved authorizations, directly preventing client-side tampering with user IDs from granting unauthorized access to other accounts or privilege escalation.

AC-6 Least Privilege good match

prevent

AC-6 enforces least privilege, blocking low-privileged users from elevating their own privileges or modifying disabled user roles.

SI-10 Information Input Validation good match

prevent

SI-10 validates information inputs on the server side, mitigating client-side tampering with user IDs and role information to prevent unauthorized modifications.

MITRE ATT&CK Enterprise TechniquesAI

change their account information. A low-privileged authenticated user can elevate his or her system privileges by modifying the information of a user role that is disabled in the client.

Deeper analysisAI

CVE-2024-50619 consists of vulnerabilities in the My Account and User Management components of CIPPlanner CIPAce versions prior to 9.17. These flaws allow attackers to escalate their access levels through improper privilege management (CWE-269). The issue carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to network accessibility, low attack complexity, and significant impacts on confidentiality, integrity, and availability.

A low-privileged authenticated user can exploit these vulnerabilities over the network without user interaction. By tampering with the client-side user ID, they can gain unauthorized access to other users' accounts and modify their information. Separately, the attacker can elevate their own system privileges by altering details of a disabled user role within the client.

The vendor has published a public notification of resolution at https://cipplanner.com/cve-2024-50619-cve-public-notification-of-resolution/, which addresses the vulnerabilities in CIPAce version 9.17 and later. Security practitioners should upgrade affected installations to mitigate the risks.
