This reduces the effectiveness\\n          and could allow exploitation in semi-reasonable amount of time.\", \"disclosure_date\": \"2010-11-01\", \"fullname\": \"exploit/linux/ftp/proftp_telnet_iac\", \"is_install_path\": true, \"mod_time\": \"2026-05-14 11:43:36 +0000\", \"name\": \"ProFTPD 1.3.2rc3 - 1.3.3b Telnet IAC Buffer Overflow (Linux)\", \"needs_cleanup\": null, \"notes\": {\"Reliability\": [\"unreliable-session\"], \"SideEffects\": [\"ioc-in-logs\"], \"Stability\": [\"crash-service-down\"]}, \"path\": \"/modules/exploits/linux/ftp/proftp_telnet_iac.rb\", \"platform\": \"Linux\", \"post_auth\": false, \"rank\": 500, \"ref_name\": \"linux/ftp/proftp_telnet_iac\", \"references\": [\"CVE-2010-4221\", \"OSVDB-68985\", \"BID-44562\"], \"rport\": 21, \"session_types\": false, \"targets\": [\"Automatic Targeting\", \"Debug\", \"ProFTPD 1.3.3a Server (Debian) - Squeeze Beta1\", \"ProFTPD 1_3_3a Server (Debian) - Squeeze Beta1 (Debug)\", \"ProFTPD 1.3.2c Server (Ubuntu 10.04)\"], \"type\": \"exploit\"}", "creation_timestamp": "2026-09-08T06:48:20.073089Z"}, {"uuid": "3f81ef7c-8fc5-404f-9e36-b21acaf79526", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2010-4221", "type": "seen", "source": "https://t.me/GithubRedTeam/101682", "content": "\ud83d\udea8 GitHub \u76d1\u63a7\u6d88\u606f\u63d0\u9192\n\n\ud83d\udea8 \u53d1\u73b0\u5173\u952e\u8bcd\uff1a #RCE #CVE\n\n\ud83d\udce6 \u9879\u76ee\u540d\u79f0\uff1a cve-2010-4221-lab\n\ud83d\udc64 \u9879\u76ee\u4f5c\u8005\uff1a diegslva\n\ud83d\udee0 \u5f00\u53d1\u8bed\u8a00\uff1a Python\n\u2b50 Star\u6570\u91cf\uff1a 0  |  \ud83c\udf74 Fork\u6570\u91cf\uff1a 0\n\ud83d\udcc5 \u66f4\u65b0\u65f6\u95f4\uff1a 2026-09-08 14:50:44\n\n\ud83d\udcdd \u9879\u76ee\u63cf\u8ff0\uff1a\nFrom patch to RCE: hand-built exploit for CVE-2010-4221 (ProFTPD TELNET IAC stack overflow), with the full failure-driven journey documented\n\n\ud83d\udd17 \u70b9\u51fb\u8bbf\u95ee\u9879\u76ee\u5730\u5740", "creation_timestamp": "2026-09-09T05:00:05.752159Z"}, {"uuid": "a32ba39d-c1ff-486d-a157-02a1304440d5", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2010-4221", "type": "published-proof-of-concept", "source": "https://t.me/GithubRedTeam/101682", "content": "\ud83d\udea8 GitHub \u76d1\u63a7\u6d88\u606f\u63d0\u9192\n\n\ud83d\udea8 \u53d1\u73b0\u5173\u952e\u8bcd\uff1a #RCE #CVE\n\n\ud83d\udce6 \u9879\u76ee\u540d\u79f0\uff1a cve-2010-4221-lab\n\ud83d\udc64 \u9879\u76ee\u4f5c\u8005\uff1a diegslva\n\ud83d\udee0 \u5f00\u53d1\u8bed\u8a00\uff1a Python\n\u2b50 Star\u6570\u91cf\uff1a 0  |  \ud83c\udf74 Fork\u6570\u91cf\uff1a 0\n\ud83d\udcc5 \u66f4\u65b0\u65f6\u95f4\uff1a 2026-09-08 14:50:44\n\n\ud83d\udcdd \u9879\u76ee\u63cf\u8ff0\uff1a\nFrom patch to RCE: hand-built exploit for CVE-2010-4221 (ProFTPD TELNET IAC stack overflow), with the full failure-driven journey documented\n\n\ud83d\udd17 \u70b9\u51fb\u8bbf\u95ee\u9879\u76ee\u5730\u5740", "creation_timestamp": "2026-09-10T00:00:50.432989Z"}]}
