Vulnerability details

Advisory: SB2013030101 - Remote code execution in Oracle Java SE

Vulnerable component: Oracle Java SE

CVE-ID: CVE-2013-1493

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-119 - Memory corruption

Description:

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

The weakness exists due to multiple integer and buffer overflows in the color management (CMM) functionality within the 2D component. A remote attacker can create specially crafted Web page, trick the victim into visiting it, trigger memory corruption using an image with crafted raster parameters and execute arbitrary code 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.

Known APT campaigns:

Sun Shop Campaign

The campaign was first detected on May 20, 2013.

Public Exploits:

- Java CMM - Remote Code Execution (Metasploit) [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.
