NOTE: the previous information is from the April 2013 CPU. Oracle has not commented on claims from the original researcher that this vulnerability allows remote attackers to bypass permission checks by the MethodHandles method and modify arbitrary public final fields using reflection and type confusion, as demonstrated using integer and double fields to disable the security manager.","published":"2013-04-17T18:55:07.000Z","lastModified":"2026-06-16T23:53:20.000Z","status":"Analyzed","sourceIdentifier":"secalert_us@oracle.com","cvss":{"version":"3.1","score":3.7,"severity":"LOW","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N"},"cwe":["CWE-284"],"affected":["oracle/jre","canonical/ubuntu linux","opensuse/opensuse"],"epss":{"score":0.85215,"percentile":0.99715,"date":"2026-10-30","history":[]},"kev":{"listed":true,"dateAdded":"2022-05-25","dueDate":"2022-06-15","knownRansomwareCampaignUse":"Unknown","notes":"Apply updates per vendor instructions.\nhttps://nvd.nist.gov/vuln/detail/CVE-2013-2423"},"exploits":{"count":1,"verified":true,"firstPublished":"2013-04-23","source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[{"edbId":24976,"kind":"exploit","title":"Java Applet - Reflection Type Confusion Remote Code Execution (Metasploit)","url":"https://www.exploit-db.com/exploits/24976","sourceUrl":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/multiple/remote/24976.rb","file":"exploits/multiple/remote/24976.rb","published":"2013-04-23","added":"2013-04-23","updated":"2013-04-23","author":"Metasploit","type":"remote","platform":"multiple","port":null,"verified":true,"codes":["CVE-2013-2423","OSVDB-92348"],"tags":"Metasploit Framework (MSF)","aliases":null,"applicationUrl":null,"screenshotUrl":null,"referenceUrl":null}]},"verdict":{"level":"urgent","text":"Known to be exploited in the wild (CISA KEV, CISA remediation deadline 15 June 2022).
