Specifically, verification stops at the first NULL byte encountered in the email address referenced in the client certificate. An attacker can exploit this vulnerability by using a specially crafted certificate with a null byte, which could <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-26210-deepseek-xss-vulnerability-allows-potential-system-compromise\/\"  data-wpil-monitor-id=\"86670\">potentially allow<\/a> them to bypass the configured ACLs.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-4236646708\" class=\"ameeb-content ameeb-entity-placement\"><div class=\"poptin-embedded\" data-id=\"f6b387694f681\"><\/div>\r\n\r\n\r\n\r\n\r\n\r\n<\/div>\n<p>A <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-9791-critical-vulnerability-in-tenda-ac20-16-03-08-05-leading-to-potential-system-compromise\/\"  data-wpil-monitor-id=\"84986\">potential exploitation of this vulnerability<\/a> might look like the following, where the attacker uses a specially crafted certificate with a NULL byte in the email address:<\/p>\n<pre><code class=\"\" data-line=\"\">openssl req -new -newkey rsa:2048 -days 365 -nodes -x509 -keyout server.key -out server.crt -subj \/C=US\/ST=Denial\/L=Springfield\/O=Dis\/CN=www.example.com\/emailAddress=attacker\\0@example.com<\/code><\/pre>\n<p>In this example, the email address `attackerIn this example, the email address `attacker\\0@example.com` includes a NULL byte (`\\0`), which could cause the verification process to stop, allowing the attacker to potentially bypass the ACLs@example.com` includes a NULL byte (`In this example, the email address `attacker\\0@example.com` includes a NULL byte (`\\0`), which could cause the verification process to stop, allowing the attacker to potentially bypass the ACLs`), which could cause the verification process to stop, <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-55743-serious-vulnerability-in-unopim-allows-potential-system-compromise\/\"  data-wpil-monitor-id=\"89704\">allowing the attacker to potentially<\/a> bypass the ACLs.
