{"cve":"CVE-2022-24823","nvd":{"published":"2022-05-06T12:15:08.163","modified":"2026-06-17T04:32:35.967","status":"Modified","description":"Netty is an open-source, asynchronous event-driven network application framework. The package `io.netty:netty-codec-http` prior to version 4.1.77.Final contains an insufficient fix for CVE-2021-21290. When Netty's multipart decoders are used local information disclosure can occur via the local system temporary directory if temporary storing uploads on the disk is enabled. This only impacts applications running on Java version 6 and lower. Additionally, this vulnerability impacts code running on Unix-like systems, and very old versions of Mac OSX and Windows as they all share the system temporary directory between all users. Version 4.1.77.Final contains a patch for this vulnerability. As a workaround, specify one's own `java.io.tmpdir` when starting the JVM or use DefaultHttpDataFactory.setBaseDir(...) to set the directory to something that is only readable by the current user.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":5.5},"cwes":["CWE-668","CWE-378","CWE-379"],"references":["https://github.com/netty/netty/commit/185f8b2756a36aaa4f973f1a2a025e7d981823f1","https://github.com/netty/netty/security/advisories/GHSA-269q-hmxg-m83q","https://github.com/netty/netty/security/advisories/GHSA-5mcr-gq6c-3hq2","https://security.netapp.com/advisory/ntap-20220616-0004/","https://www.oracle.com/security-alerts/cpujul2022.html"],"products":["netapp:active_iq_unified_manager","netapp:oncommand_workflow_automation","netapp:snapcenter","netty:netty","oracle:financial_services_crime_and_compliance_management_studio"],"source":"nvd","synced_at":"2026-10-19T21:31:59.322382750+00:00"},"epss":{"cve":"CVE-2022-24823","score":0.01044,"percentile":0.64149,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-269q-hmxg-m83q","url":"https://osv.dev/vulnerability/GHSA-269q-hmxg-m83q","summary":"Local Information Disclosure Vulnerability in io.netty:netty-codec-http","modified":"2026-08-07T08:11:54.278779720Z","packages":[{"ecosystem":"Maven","name":"io.netty:netty-codec-http","purl":"pkg:maven/io.netty/netty-codec-http","ranges":["<4.1.77.Final"],"fixed":["4.1.77.Final"]}]}],"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).
