CVE-2015-2545 is a vulnerability discovered in 2015 and corrected with Microsoft’s update MS15-099. The vulnerability affects Microsoft Office versions 2007 SP3, 2010 SP2, 2013 SP1 and 2013 RT SP1.

The error enables an attacker to execute arbitrary code using a specially crafted EPS image file. The exploit uses PostScript and can evade Address Space Layout Randomization (ASLR) and Data Execution Prevention (DEP) protection methods.

The exploit was discovered in the wild in August 2015, when it was used in a targeted attack by the Platinum group, presumably against targets in India. Over the following months, there was significant growth in the number of threat actors using the vulnerability as a primary tool for initial penetration, with both the attack groups and their targets located in South-East and Central Asia and the Far East.

In this research paper, we discuss examples of attacks using the CVE-2015-2545 vulnerability undertaken by some of these groups.
