CVE-2012-10055

46
FAUCET Score

CVE-2012-10055 describes a critical format string vulnerability in ComSndFTP FTP Server version 1.3.7 Beta. An unauthenticated remote attacker can exploit a specially crafted USER command to overwrite a hardcoded function pointer, specifically WSACleanup, in memory. This allows for arbitrary code execution by redirecting execution flow and bypassing DEP protections using a ROP chain. With a CVSS score of 9.3 (CRITICAL) and an EPSS score indicating high exploitability, this vulnerability poses a significant risk due to its network-based attack vector and low attack complexity. Exploit modules are available in Metasploit, and there is substantial community discussion, though it is not listed on the KEV catalog or Hot List.
