CVE-2011-10015

39
FAUCET Score

CVE-2011-10015 describes a critical stack-based buffer overflow in Cytel Studio version 9.0 and earlier. This vulnerability allows arbitrary code execution when a user opens a specially crafted .CY3 file, due to the application's failure to perform proper bounds checking when copying user-controlled data into a fixed-size buffer. With a CVSS score of 9.3 (CRITICAL), it presents a significant risk, requiring user interaction but with low attack complexity. Exploit code is publicly available via a Metasploit module, though there is no evidence of active exploitation or significant community discussion.
