{"cve":"CVE-2012-10055","nvd":{"published":"2025-08-13T21:15:29.840","modified":"2026-06-16T23:38:45.447","status":"Deferred","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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":9.3},"cvss_v3":null,"cwes":["CWE-134"],"references":["https://raw.githubusercontent.com/rapid7/metasploit-framework/master/modules/exploits/windows/ftp/comsnd_ftpd_fmtstr.rb","https://web.archive.org/web/20120317214524/http://ftp.comsnd.com/","https://www.exploit-db.com/exploits/19024","https://www.exploit-db.com/exploits/19177","https://www.vulncheck.com/advisories/comsndftp-user-format-string-rce"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:06:45.861874017+00:00"},"epss":{"cve":"CVE-2012-10055","score":0.02371,"percentile":0.83838,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
