CVE-2012-10055 | BDVDB-2026-289448 Detail
ComSndFTPFTP Server
Description#
ComSndFTP FTP Server version 1.3.7 Beta contains a format string vulnerability in its handling of the USER command. By sending a specially crafted username containing format specifiers, a remote attacker can overwrite a hardcoded function pointer in memory (specifically WSACleanup from Ws2_32.dll). This allows the attacker to redirect execution flow and bypass DEP protections using a ROP chain, ultimately leading to arbitrary code execution. The vulnerability is exploitable without authentication and affects default configurations.

CAPEC-135 Format String Injection
Weaknesses#
- CWE-134 Use of Externally-Controlled Format String
