Detailsinfo

A vulnerability classified as critical has been found in Cytel Studio up to 9.0. Affected is an unknown code of the component CY3 File Handler. The manipulation with an unknown input leads to a stack-based overflow vulnerability. CWE is classifying the issue as CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Cytel Studio version 9.0 and earlier is vulnerable to a stack-based buffer overflow triggered by parsing a malformed .CY3 file. The vulnerability occurs when the application copies user-controlled strings into a fixed-size stack buffer (256 bytes) without proper bounds checking. Exploitation allows arbitrary code execution when the crafted file is opened.

The weakness was presented by Luigi Auriemma. The advisory is available at raw.githubusercontent.com. This vulnerability is traded as CVE-2011-10015 since 08/12/2025. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Successful exploitation requires user interaction by the victim. Technical details are unknown but a public exploit is available.

The exploit is shared for download at exploit-db.com. It is declared as proof-of-concept.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The vulnerability is also documented in the vulnerability database at Exploit-DB (17930). If you want to get best quality of vulnerability data, you may have to visit VulDB.
