{"id":"UBUNTU-CVE-2023-36325","details":"i2p before 2.3.0 (Java) allows de-anonymizing the public IPv4 and IPv6 addresses of i2p hidden services (aka eepsites) via a correlation attack across the IPv4 and IPv6 addresses that occurs when a tunneled, replayed message has a behavior discrepancy (it may be dropped, or may result in a Wrong Destination response). An attack would take days to complete.","modified":"2025-10-24T05:02:07Z","published":"2024-10-09T06:15:00Z","upstream":["CVE-2023-36325"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-36325"},{"type":"REPORT","url":"https://xeiaso.net/blog/CVE-2023-36325"},{"type":"REPORT","url":"https://geti2p.net/en/blog/post/2023/06/25/new_release_2.3.0"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2023-36325"}],"affected":[{"package":{"name":"i2p","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/i2p@0.9.34-1ubuntu3?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.9.30-4","0.9.32-2","0.9.34-1ubuntu1","0.9.34-1ubuntu3"],"ecosystem_specific":{"binaries":[{"binary_name":"i2p","binary_version":"0.9.34-1ubuntu3"},{"binary_name":"i2p-router","binary_version":"0.9.34-1ubuntu3"},{"binary_version":"0.9.34-1ubuntu3","binary_name":"libjbigi-jni"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-36325.json"}},{"package":{"name":"i2p","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/i2p@0.9.44-3?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.9.41-2","0.9.42-1","0.9.44-1","0.9.44-2","0.9.44-3"],"ecosystem_specific":{"binaries":[{"binary_name":"i2p","binary_version":"0.9.44-3"},{"binary_name":"i2p-router","binary_version":"0.9.44-3"},{"binary_name":"libjbigi-jni","binary_version":"0.9.44-3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-36325.json"}},{"package":{"name":"i2p","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/i2p@0.9.48-1?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.9.48-1"],"ecosystem_specific":{"binaries":[{"binary_name":"i2p","binary_version":"0.9.48-1"},{"binary_name":"i2p-router","binary_version":"0.9.48-1"},{"binary_name":"libjbigi-jni","binary_version":"0.9.48-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-36325.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N"},{"type":"Ubuntu","score":"medium"}]}
