CVE-2024-38499 in CA Client Automation
Summary
by MITRE • 12/17/2024
CA Client Automation (ITCM) allows non-admin/non-root users to encrypt a string using CAF CLI and SD_ACMD CLI. This would allow the non admin user to access the critical encryption keys which further causes the exploitation of stored credentials. This fix doesn't allow a non-admin/non-root user to execute "caf encrypt"/"sd_acmd encrypt" commands.

The vulnerability identified as CVE-2024-38499 affects CA Client Automation (ITCM) systems where unauthorized users can exploit command line interfaces to perform encryption operations. This represents a significant security weakness in the privilege management architecture of the platform. The flaw specifically exists within the CAF CLI and SD_ACMD CLI interfaces which permit unprivileged users to execute encryption commands that should typically be restricted to administrative or root-level accounts. The vulnerability stems from inadequate access controls and privilege separation mechanisms within the encryption functionality of the software.
The technical implementation of this vulnerability allows non-administrative users to invoke encryption functions through command line interfaces that are not properly gated by authentication or authorization checks. When users execute the "caf encrypt" or "sd_acmd encrypt" commands, they gain access to encryption key material that should remain protected and restricted to authorized personnel only. This access to critical encryption keys enables attackers to decrypt stored credentials that were previously protected by the encryption mechanisms. The flaw creates an attack vector where privilege escalation occurs through legitimate system interfaces that are not properly secured against unauthorized usage.
The operational impact of this vulnerability extends beyond simple unauthorized access to encryption keys. Attackers can leverage this weakness to extract sensitive information from systems that rely on the encryption mechanisms for credential protection. This creates a cascading security risk where compromised encryption keys can be used to decrypt other protected data within the system. The vulnerability undermines the fundamental security model of the platform by allowing users to bypass intended access controls and potentially gain access to confidential information that should remain protected. Organizations using CA Client Automation may face unauthorized data access, credential theft, and potential system compromise through this vulnerability.
The fix for CVE-2024-38499 involves implementing proper access controls that prevent non-administrative and non-root users from executing encryption commands through the affected CLI interfaces. This remediation aligns with security best practices outlined in the CWE (Common Weakness Enumeration) framework, specifically addressing CWE-284 which covers improper access control and CWE-310 which deals with cryptographic weaknesses. The solution should enforce strict privilege checks before allowing encryption operations to proceed, ensuring that only authorized administrative users can execute these commands. Organizations should also consider implementing additional monitoring and logging of encryption-related activities to detect potential exploitation attempts. The mitigation strategy should be consistent with ATT&CK framework techniques related to privilege escalation and credential access, particularly focusing on T1078 for valid accounts and T1552 for credentials from password stores. Regular security assessments of CLI interfaces and privilege management systems should be conducted to prevent similar vulnerabilities from emerging in other components of the automation platform.
