What is CVE-2011-10015?

Cytel Studio, specifically version 9.0 and earlier, is vulnerable to a stack-based buffer overflow that can be exploited by opening a specially crafted .CY3 file. This vulnerability arises from the application's failure to perform proper bounds checking when copying user-controlled strings into a fixed-size stack buffer of 256 bytes. Successful exploitation can lead to arbitrary code execution, potentially allowing an attacker to gain control of the affected system.

Affected Version(s)

Studio * <= 9.0

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
