CVE-2006-0616

Vulnerability

CVE-2006-0616 is an unspecified vulnerability in the Sun Java JDK and JRE 5.0 Update 4 and earlier. It is one of several issues in the Java Reflection API that allow an untrusted Java applet to bypass the Java sandbox security restrictions [2]. The exact vector is not disclosed, but it involves the reflection APIs [2]. Affected versions include JDK and JRE 5.0 Update 4 and earlier, as well as SDK and JRE 1.4.2_09 and earlier, and SDK and JRE 1.3.1_17 and earlier for related issues [2].

Exploitation

An attacker can exploit this vulnerability by convincing a user to run a specially crafted Java applet [2]. No authentication is required, and the attack can be launched remotely. Web browsers with Java support may automatically run applets from untrusted websites, providing a vector for exploitation [2]. The attacker crafts an applet that uses the reflection APIs to elevate its privileges beyond the sandbox restrictions [3].

Impact

Successful exploitation allows the attacker to bypass Java sandbox restrictions and execute arbitrary code with the privileges of the user running the applet [2][3]. This can lead to access to local files, arbitrary network connections, and full control over the user's machine [3].

Mitigation

Sun addressed the fourth issue (CVE-2006-0616) in JDK and JRE 5.0 Update 5 and later [2]. For related issues, updates are available in JDK/JRE 1.4.2_10 and later, and 1.3.1_17 and later [2]. Gentoo Linux recommends upgrading to >=dev-java/sun-jdk-1.4.2.10 or >=dev-java/sun-jre-bin-1.4.2.10 [3]. No workaround is available; users should apply the appropriate patches.
