{"id":"CVE-2017-15708","url":"https://www.cyber-defence.io/tools/cve/CVE-2017-15708","generatedAt":"2026-10-28T20:07:30.241Z","title":"In Apache Synapse, by default no authentication is required for Java Remote Method Invocation (RMI).","description":"In Apache Synapse, by default no authentication is required for Java Remote Method Invocation (RMI). So Apache Synapse 3.0.1 or all previous releases (3.0.0, 2.1.0, 2.0.0, 1.2, 1.1.2, 1.1.1) allows remote code execution attacks that can be performed by injecting specially crafted serialized objects. And the presence of Apache Commons Collections 3.2.1 (commons-collections-3.2.1.jar) or previous versions in Synapse distribution makes this exploitable. To mitigate the issue, we need to limit RMI access to trusted users only. Further upgrading to 3.0.1 version will eliminate the risk of having said Commons Collection version. In Synapse 3.0.1, Commons Collection has been updated to 3.2.2 version.","published":"2017-12-11T15:29:00.000Z","lastModified":"2026-06-17T01:08:08.000Z","status":"Modified","sourceIdentifier":"security@apache.org","cvss":{"version":"3.1","score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-74"],"affected":["apache/synapse","oracle/financial services market risk measurement and management","oracle/peoplesoft enterprise peopletools"],"epss":{"score":0.1788,"percentile":0.9716,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"urgent","text":"EPSS puts the probability of exploitation in the next 30 days at 17.9%, higher than 97% of all known CVEs.
