Introduction ============ Multiple critical vulnerabilities were identified in JDA Connect. The vulnerabilities were discovered during a black box security assessment and therefore the vulnerability list should not be considered exhaustive.
Affected Software and Versions ============================== - Tested with JDA Connect (most recent version at the date of July 2017) - All vulnerabilities are fixed as of patch 2017.2 CVE === No CVEs have been assigned yet. Author ====== The vulnerabilities were discovered by Xiaoran Wang from Google Security Team. Credit ====== The author would like to thank John Vrankovich from JDA for coordinating the security fixes promptly and diligently. Vulnerability Overview ====================== CNT-01 - Privileged remote command execution through open CORS policies CNT-02 - No CSRF protection on hawtio web portal CNT-03 - Unauthenticated JMX service listening on all interfaces Vulnerability Details ===================== ---------------------------------------------------------------------------- CNT-01 - Privileged remote command execution through open CORS policies ---------------------------------------------------------------------------- Severity: CRITICAL The hawtio admin web portal running on port 8181 has a insecure wide open “Access-Control-Allow-Origin” setting and it allows any arbitrary origin to access its data by echoing back “Access-Control-Allow-Origin: attacker-supplied-origin” and “Access-Control-Allow-Credentials: true”. This allows the attacker to communicate with the vulnerable website from an attacker’s website as if they were on the same origin. This enables the attacker to take send and receive any request this website accepts because it’s cookie authenticated. Example requests include dumping heap memory, reading/writing JVM options, reading/writing object values, installing arbitrary features/bundles, and the servlet handler runs as root. ---------------------------------------------------------------------------- CNT-02 - No CSRF protection on hawtio web portal ---------------------------------------------------------------------------- Severity: HIGH The hawtio admin web portal running on port 8181 does not have any CSRF protection, leading to the same results as the previous vulnerability, such as installing arbitrary packages, reading/writing JVM memory, etc. ---------------------------------------------------------------------------- CNT-03 - Unauthenticated JMX service listening on all interfaces ---------------------------------------------------------------------------- Severity: HIGH The JDA Connect Java daemon has a JMX server that listens on all interfaces without authentication. Using tools like jconsole, one could read and write the values of objects in the entire application, possibly leading to arbitrary command execution. For example, the Java process is started with the following options. -Dcom.sun.management.jmxremote.port=1616 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false _______________________________________________ Sent through the Full Disclosure mailing list https://nmap.org/mailman/listinfo/fulldisclosure Web Archives & RSS: http://seclists.org/fulldisclosure/
