A conceptual example might look like this:<\/p>\n<pre><code class=\"\" data-line=\"\">POST \/KACE_SMA\/validate_2FA HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/json\nCookie: Authenticated_User_Session=...\n{\n&quot;user&quot;: &quot;attacker&quot;,\n&quot;pass&quot;: &quot;attacker_password&quot;,\n&quot;2FA_token&quot;: &quot;bypassed_value&quot;\n}<\/code><\/pre>\n<p>In the above request, the attacker uses their valid credentials but provides a manipulated or <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-49151-unauthenticated-attackers-can-forge-json-web-tokens-in-microsens-nmp-web\/\"  data-wpil-monitor-id=\"64553\">bypassed<\/a> 2FA token. Due to the logic flaw in the 2FA validation process, the SMA may grant elevated <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-25268-unauthenticated-adjacent-attacker-accessing-api-endpoint\/\"  data-wpil-monitor-id=\"77741\">access to the attacker<\/a> despite the invalid 2FA token.<br \/>\nTo mitigate this vulnerability, apply the vendor-provided patch as soon as possible. If this is not immediately possible, consider implementing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary countermeasure. However, these should not be seen as a long-term solution, as they may not fully prevent exploitation of the vulnerability.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Overview In this blog post, we will delve into the details of a critical vulnerability, CVE-2025-32976, that affects Quest KACE Systems Management Appliance (SMA).
