{"id":"CVE-2023-36474","summary":"Interactsh server settings make users vulnerable to Subdomain Takeover","details":"Interactsh is an open-source tool for detecting out-of-band interactions. Domains configured with interactsh server prior to version 1.0.0 were vulnerable to subdomain takeover for a specific subdomain, i.e `app.` Interactsh server used to create cname entries for `app` pointing to `projectdiscovery.github.io` as default, which intended to used for hosting interactsh web client using GitHub pages. This is a security issue with a self-hosted interactsh server in which the user may not have configured a web client but still have a CNAME entry pointing to GitHub pages, making them vulnerable to subdomain takeover. This allows a threat actor to host / run arbitrary client side code (cross-site scripting) in a user's browser when browsing the vulnerable subdomain. Version 1.0.0 fixes this issue by making CNAME optional, rather than default.","aliases":["GHSA-m36x-mgfh-8g78","GO-2022-0372"],"modified":"2026-08-12T03:30:37.824707486Z","published":"2023-06-28T21:20:22.455Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-79"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/36xxx/CVE-2023-36474.json"},"references":[{"type":"WEB","url":"https://labs.detectify.com/2014/10/21/hostile-subdomain-takeover-using-herokugithubdesk-more/"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/36xxx/CVE-2023-36474.json"},{"type":"ADVISORY","url":"https://github.com/projectdiscovery/interactsh/security/advisories/GHSA-m36x-mgfh-8g78"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-36474"},{"type":"REPORT","url":"https://github.com/projectdiscovery/interactsh/issues/136"},{"type":"FIX","url":"https://github.com/projectdiscovery/interactsh/pull/155"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/projectdiscovery/interactsh","events":[{"introduced":"0"},{"fixed":"18f2f6453d0eff62eaacd8ab371238e92c54fc9a"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.0.0"}],"source":["AFFECTED_FIELD","CPE_RANGE"],"cpe":"cpe:2.3:a:projectdiscovery:interactsh:*:*:*:*:*:*:*:*"}}],"versions":["v0.0.7","v0.0.5","v0.0.6","v0.0.4","v0.0.3","v0.0.2"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2023-36474.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:H/A:N"}]}
