{"cve":"CVE-2017-5641","nvd":{"published":"2017-12-28T15:29:00.303","modified":"2026-06-17T01:20:54.510","status":"Modified","description":"Previous versions of Apache Flex BlazeDS (4.7.2 and earlier) did not restrict which types were allowed for AMF(X) object deserialization by default. During the deserialization process code is executed that for several known types has undesired side-effects. Other, unknown types may also exhibit such behaviors. One vector in the Java standard library exists that allows an attacker to trigger possibly further exploitable Java deserialization of untrusted data. Other known vectors in third party libraries can be used to trigger remote code execution.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-502"],"references":["http://mail-archives.apache.org/mod_mbox/flex-dev/201703.mbox/%3C6B86C8D0-6E36-48F5-AC81-4AB3978F6746%40c-ware.de%3E","http://www.securityfocus.com/bid/97383","http://www.securitytracker.com/id/1038273","https://issues.apache.org/jira/browse/FLEX-35290","https://support.hpe.com/hpsc/doc/public/display?docLocale=en_US&docId=emr_na-hpesbhf03823en_us"],"products":["apache:flex_blazeds","hp:xp_command_view_advanced_edition"],"source":"nvd","synced_at":"2026-10-19T20:47:56.471723566+00:00"},"epss":{"cve":"CVE-2017-5641","score":0.20747,"percentile":0.97537,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-w8v7-prhw-xjpw","url":"https://osv.dev/vulnerability/GHSA-w8v7-prhw-xjpw","summary":"Apache Flex BlazeDS unsafe deserialization","modified":"2024-02-16T08:00:32.866084Z","packages":[{"ecosystem":"Maven","name":"org.apache.flex.blazeds:flex-messaging-core","purl":"pkg:maven/org.apache.flex.blazeds/flex-messaging-core","ranges":["<4.7.3"],"fixed":["4.7.3"]},{"ecosystem":"Maven","name":"org.apache.flex.blazeds:flex-messaging-remoting","purl":"pkg:maven/org.apache.flex.blazeds/flex-messaging-remoting","ranges":["<4.7.3"],"fixed":["4.7.3"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
