An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-34234 exists.\n\nAffected product: Ctrlpanel-gg panel. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-34234/ (Markdown: https://insights.sbomify.com/CVE-2026-34234/index.md)","id":"CVE-2026-34234","markdown":"https://insights.sbomify.com/CVE-2026-34234/index.md","name":"CVE-2026-34234","record":{"aliases":["GHSA-jmhr-q9q5-fqwh"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"CtrlPanel billing software","requires_auth":"none","summary":"Unauthenticated attackers can execute arbitrary commands on CtrlPanel servers via the installer script due to missing lock checks and unsanitized input.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"},{"id":"CWE-284","name":"Improper Access Control"}],"description":"CtrlPanel is open-source billing software for hosting providers. In versions 1.1.1 and prior, the web-based installer (public/installer/index.php) is vulnerable to unauthenticated Remote Code Execution (RCE) because it performs the install.lock check only after including and executing form handler files, leaving installer endpoints reachable on already-installed instances. The handlers also pass unsanitized user input directly into shell commands, allowing an attacker to submit crafted requests that execute arbitrary commands on the server. The vulnerability stems from two combined weaknesses: (1) premature form handler execution before the lock file gate, and (2) unsafe use of user input in shell command construction. This issue is reported to be actively exploited in the wild. The issue has been fixed in version 1.2.0.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-06-04","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":1,"refs":[{"date":"2026-06-04T13:54:37Z","kind":"github_poc","ref":"https://github.com/rootdirective-sec/CVE-2026-34234-Lab","stars":0,"title":null},{"date":null,"kind":"nuclei","ref":"http/cves/2026/CVE-2026-34234.yaml","stars":null,"title":"CtrlPanel \u003c= 1.1.1 - Remote Code Execution"}],"tier":"weaponised"},"has_fix":false,"headline":"CtrlPanel: Unauthenticated RCE using installer script","id":"CVE-2026-34234","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"PJSIP: Heap OOB read in VPX unpacketizer","id":"CVE-2026-34235"},"packages":[],"prev":{"headline":"CtrlPanel has Missing Authentication Checks in Datatable Admin Endpoints","id":"CVE-2026-34233"},"products":["panel"],"published":"2026-05-19","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"yes","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-05-20","vendors":["Ctrlpanel-gg"]},"summary":"Unauthenticated attackers can execute arbitrary commands on CtrlPanel servers via the installer script due to missing lock checks and unsanitized input.","url":"https://insights.sbomify.com/CVE-2026-34234/"}
