When creating .htaccess files, the inHTUsername field is passed unsanitized to a system() call that invokes the system’s htpasswd binary. By injecting shell metacharacters into the username field, an authenticated attacker can execute arbitrary system commands. Exploitation requires a valid ZPanel account—such as one in the default Users, Resellers, or Administrators groups—but no elevated privileges.", "aliases": [ { "alias": "CVE-2013-10053" } ], "fixed_packages": [], "affected_packages": [], "references": [ { "reference_url": "https://api.first.org/data/v1/epss?cve=CVE-2013-10053", "reference_id": "", "reference_type": "", "scores": [ { "value": "0.79731", "scoring_system": "epss", "scoring_elements": "0.99123", "published_at": "2026-06-14T12:55:00Z" }, { "value": "0.79731", "scoring_system": "epss", "scoring_elements": "0.99122", "published_at": "2026-06-13T12:55:00Z" }, { "value": "0.79731", "scoring_system": "epss", "scoring_elements": "0.99119", "published_at": "2026-06-11T12:55:00Z" } ], "url": "https://api.first.org/data/v1/epss?cve=CVE-2013-10053" }, { "reference_url": "https://web.archive.org/web/20130617014355/http://forums.zpanelcp.com/showthread.php?27898-Serious-Remote-Execution-Exploit-in-Zpanel-10-0-0-2", "reference_id": "showthread.php?27898-Serious-Remote-Execution-Exploit-in-Zpanel-10-0-0-2", "reference_type": "", "scores": [ { "value": "8.7", "scoring_system": "cvssv4", "scoring_elements": "CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N" }, { "value": "Track*", "scoring_system": "ssvc", "scoring_elements": "SSVCv2/E:P/A:N/T:T/P:M/B:A/M:M/D:R/2025-08-04T16:04:07Z/" } ], "url": "https://web.archive.org/web/20130617014355/http://forums.zpanelcp.com/showthread.php?27898-Serious-Remote-Execution-Exploit-in-Zpanel-10-0-0-2" }, { "reference_url": "https://www.vulncheck.com/advisories/zpanel-htpasswd-module-username-command-execution", "reference_id": "zpanel-htpasswd-module-username-command-execution", "reference_type": "", "scores": [ { "value": "8.7", "scoring_system": "cvssv4", "scoring_elements": "CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N" }, { "value": "Track*", "scoring_system": "ssvc", "scoring_elements": "SSVCv2/E:P/A:N/T:T/P:M/B:A/M:M/D:R/2025-08-04T16:04:07Z/" } ], "url": "https://www.vulncheck.com/advisories/zpanel-htpasswd-module-username-command-execution" }, { "reference_url": "https://raw.githubusercontent.com/rapid7/metasploit-framework/master/modules/exploits/unix/webapp/zpanel_username_exec.rb", "reference_id": "zpanel_username_exec.rb", "reference_type": "", "scores": [ { "value": "8.7", "scoring_system": "cvssv4", "scoring_elements": "CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N" }, { "value": "Track*", "scoring_system": "ssvc", "scoring_elements": "SSVCv2/E:P/A:N/T:T/P:M/B:A/M:M/D:R/2025-08-04T16:04:07Z/" } ], "url": "https://raw.githubusercontent.com/rapid7/metasploit-framework/master/modules/exploits/unix/webapp/zpanel_username_exec.rb" }, { "reference_url": "https://github.com/zpanel/zpanelx", "reference_id": "zpanelx", "reference_type": "", "scores": [ { "value": "8.7", "scoring_system": "cvssv4", "scoring_elements": "CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N" }, { "value": "Track*", "scoring_system": "ssvc", "scoring_elements": "SSVCv2/E:P/A:N/T:T/P:M/B:A/M:M/D:R/2025-08-04T16:04:07Z/" } ], "url": "https://github.com/zpanel/zpanelx" } ], "weaknesses": [ { "cwe_id": 78, "name": "Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')", "description": "The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component." } ], "exploits": [ { "date_added": null, "description": "This module exploits a vulnerability found in ZPanel's htpasswd module.
