In June 2025, multiple critical vulnerabilities were disclosed. These include CVE-2025-32975, an authentication bypass; CVE-2025-32976, a 2FA bypass; CVE-2025-32977, malicious backup upload; and CVE-2025-32978, license replacement leading to denial of service. The vulnerabilities were discovered during a third-party assessment. As of March 20, 2026, active exploitation has been reported, making immediate patching critical. Versions affected include KACE SMA versions 13.0.385, 13.1.81, 13.2.183, 14.0.341, and 14.1.101. Successful exploitation can lead to complete system compromise, impacting enterprise security and operations.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003e\u003cstrong\u003eUnauthenticated Request (CVE-2025-32975):\u003c/strong\u003e An attacker sends a crafted request to the KACE SMA server, exploiting the improper authentication handling in the SSO mechanism.\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eAuthentication Bypass:\u003c/strong\u003e The server fails to properly validate the request, allowing the attacker to bypass authentication and impersonate a legitimate user, gaining unauthorized access to the system.\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003e2FA Bypass (CVE-2025-32976):\u003c/strong\u003e If the attacker has valid credentials, they exploit a logic flaw in the two-factor authentication implementation to bypass TOTP-based 2FA requirements.\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003ePrivilege Escalation:\u003c/strong\u003e Using the bypassed authentication, the attacker gains access to administrative privileges within the KACE SMA.\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eMalicious Backup Upload (CVE-2025-32977):\u003c/strong\u003e An unauthenticated attacker uploads a malicious backup file to the system, exploiting weaknesses in the cryptographic signature validation process.\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eSystem Compromise:\u003c/strong\u003e The malicious backup content is processed, compromising the system\u0026rsquo;s integrity and potentially allowing the attacker to execute arbitrary code.\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eLicense Replacement (CVE-2025-32978):\u003c/strong\u003e The attacker uses a web interface intended for license renewal to replace valid system licenses with expired or trial licenses.\u003c/li\u003e\n\u003cli\u003e\u003cstrong\u003eDenial of Service:\u003c/strong\u003e The replacement of valid licenses causes a denial of service, disrupting normal operations and preventing legitimate users from accessing the system.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of these vulnerabilities allows attackers to gain complete control over the KACE SMA, leading to the compromise of managed endpoints.
