ZKTeco ZKBioSecurity 3.0 contains hardcoded credentials in the bundled Apache Tomcat server that allow unauthenticated attackers to access the manager application. Attackers can authenticate with hardcoded credentials stored in tomcat-users.xml to upload malicious WAR archives containing JSP applications and execute arbitrary code with SYSTEM privileges.
AnalysisAI
Critical hardcoded credentials vulnerability in ZKTeco ZKBioSecurity 3.0's bundled Apache Tomcat server that allows unauthenticated remote attackers to upload malicious WAR files and execute arbitrary code with SYSTEM privileges. Multiple public exploits are available (Exploit-DB, Packet Storm), making this a high-risk vulnerability for organizations using this biometric security management software.
Technical ContextAI
The vulnerability stems from hardcoded credentials in the tomcat-users.xml configuration file of the bundled Apache Tomcat server within ZKTeco ZKBioSecurity (CPE: cpe:2.3:a:zkteco_inc.:zkteco_zkbiosecurity:*:*:*:*:*:*:*:*). This is a classic CWE-798 (Use of Hard-coded Credentials) issue where default credentials are embedded in the application distribution. The affected version 3.0.1.0_R_230 includes a Tomcat manager application accessible with these static credentials, allowing attackers to deploy arbitrary Java web applications (WAR files) containing malicious JSP code.
RemediationAI
No specific patch information is available in the provided references. Immediate actions include: 1) Disable or restrict network access to the Tomcat manager application, 2) Change the default credentials in tomcat-users.xml if possible, 3) Consider upgrading to a newer version of ZKBioSecurity if available, 4) Implement network segmentation to limit exposure of the management interface. Contact ZKTeco for vendor-specific patches or updates. The VulnCheck advisory (https://www.vulncheck.com/advisories/zkteco-zkbiosecurity-hardcoded-credentials-remote-code-execution) may contain additional remediation details.
