{"id":"UBUNTU-CVE-2020-22083","details":"** DISPUTED ** jsonpickle through 1.4.1 allows remote code execution during deserialization of a malicious payload through the decode() function. Note: It has been argued that this is expected and clearly documented behaviour. pickle is known to be capable of causing arbitrary code execution, and must not be used with un-trusted data.","modified":"2020-12-17T16:15:00Z","published":"2020-12-17T16:15:00Z","withdrawn":"2025-06-23T15:53:43Z","references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2020-22083"},{"type":"REPORT","url":"https://gist.github.com/j0lt-github/bb543e77a1a10c33cb56cf23d0837874"},{"type":"REPORT","url":"https://github.com/j0lt-github/python-deserialization-attack-payload-generator"},{"type":"REPORT","url":"https://github.com/jsonpickle/jsonpickle/issues/332"},{"type":"REPORT","url":"https://versprite.com/blog/application-security/into-the-jar-jsonpickle-exploitation/"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2020-22083"}],"affected":[{"package":{"name":"jsonpickle","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/jsonpickle"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.8.0-1build1","0.9.2-1"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2020/UBUNTU-CVE-2020-22083.json"}},{"package":{"name":"jsonpickle","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/jsonpickle"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.9.5-0ubuntu1","0.9.5-1"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2020/UBUNTU-CVE-2020-22083.json"}},{"package":{"name":"jsonpickle","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/jsonpickle"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.9.5-1","1.2-1"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2020/UBUNTU-CVE-2020-22083.json"}},{"package":{"name":"jsonpickle","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/jsonpickle"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.2-1","2.0.0+dfsg1-1"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2020/UBUNTU-CVE-2020-22083.json"}},{"package":{"name":"jsonpickle","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/jsonpickle"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.0.0+dfsg1-1","3.0.2+dfsg-1","3.0.3+dfsg-1"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2020/UBUNTU-CVE-2020-22083.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
