Vulnerability details

Advisory: SB2013011001 - Remote code execution in Oracle Java SE

Vulnerable component: Oracle Java SE

CVE-ID: CVE-2013-0422

CVSSv3 score: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H/E:H/RL:O/RC:C

CWE-ID: CWE-399 - Resource Management Errors

Description:

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The weakness exists due to errors involving Java Management Extensions (JMX) MBean components. A remote attacker can create specially crafted Web site containing a malicious Java applet, trick the victim into opening it, invoke the setSecurityManager() function and execute arbitrary code outside the sandbox with privileges of the current user.

Successful exploitation of the vulnerability results in arbitrary code execution on the vulnerable system.

Note: the vulnerability was being actively exploited.

Public Exploits:

- Java Applet JMX - Remote Code Execution (Metasploit) (1) [Exploit-DB]

About zero-day vulnerabilities

Zero-day vulnerability is an undisclosed vulnerability in software that hackers can exploit to compromise computer programs, gain unauthorized access to sensitive data, penetrate networks, etc. We consider vulnerability a zero-day when there is no solution provided from software vendor and the vulnerability is being actively exploited by malicious actors.

Zero-day candidate is a potential zero-day vulnerability in software which might have been used in targeted attacks, however there is no evidence to support this suggestion.
