An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2013-0422 in the wild since at least 25 May 2022, including in ransomware campaigns.\n\nAffected product: Canonical Ubuntu Linux. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2013-0422/ (Markdown: https://insights.sbomify.com/CVE-2013-0422/index.md)","id":"CVE-2013-0422","markdown":"https://insights.sbomify.com/CVE-2013-0422/index.md","name":"CVE-2013-0422","record":{"aliases":["GHSA-r293-6mhc-29xx"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Java Runtime Environment","requires_auth":"none","summary":"Remote attackers can execute arbitrary code by bypassing Java security checks via JMX and Reflection API flaws, requiring an upgrade to Java 7 Update 11.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"oracle","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"opensuse","vendor":"opensuse"},{"product":"jdk","vendor":"oracle"},{"product":"jre","vendor":"oracle"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"Multiple vulnerabilities in Oracle Java 7 before Update 11 allow remote attackers to execute arbitrary code by (1) using the public getMBeanInstantiator method in the JmxMBeanServer class to obtain a reference to a private MBeanInstantiator object, then retrieving arbitrary Class references using the findClass method, and (2) using the Reflection API with recursion in a way that bypasses a security check by the java.lang.invoke.MethodHandles.Lookup.checkSecurityManager method due to the inability of the sun.reflect.Reflection.getCallerClass method to skip frames related to the new reflection API, as exploited in the wild in January 2013, as demonstrated by Blackhole and Nuclear Pack, and a different vulnerability than CVE-2012-4681 and CVE-2012-3174. NOTE: some parties have mapped the recursive Reflection API issue to CVE-2012-3174, but CVE-2012-3174 is for a different vulnerability whose details are not public as of 20130114.  CVE-2013-0422 covers both the JMX/MBean and Reflection API issues.  NOTE: it was originally reported that Java 6 was also vulnerable, but the reporter has retracted this claim, stating that Java 6 is not exploitable because the relevant code is called in a way that does not bypass security checks.  NOTE: as of 20130114, a reliable third party has claimed that the findClass/MBeanInstantiator vector was not fixed in Oracle Java 7 Update 11.  If there is still a vulnerable condition, then a separate CVE identifier might be created for the unfixed issue.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2013-01-10","github_poc":0,"max_poc_stars":null,"metasploit":1,"nuclei":0,"refs":[{"date":"2013-01-10","kind":"metasploit","ref":"exploit/multi/browser/java_jre17_jmxbean","stars":null,"title":"Java Applet JMX Remote Code Execution"},{"date":"2013-01-11","kind":"exploitdb","ref":"24045","stars":null,"title":"Java Applet JMX - Remote Code Execution (Metasploit) (1)"}],"tier":"exploited"},"has_fix":true,"headline":"Oracle JRE Remote Code Execution","id":"CVE-2013-0422","indexable":true,"kev":{"dateAdded":"2022-05-25","dueDate":"2022-06-15","knownRansomwareCampaignUse":"Known","product":"Java Runtime Environment (JRE)","requiredAction":"Apply updates per vendor instructions.","vendorProject":"Oracle","vulnerabilityName":"Oracle JRE Remote Code Execution Vulnerability"},"kind":"cve","links":{"ecosystem":null,"product":"canonical:ubuntu_linux","products":["canonical:ubuntu_linux","opensuse:opensuse","oracle:jdk","oracle:jre"],"type":"security_feature_bypass","year":"2013"},"n_packages":0,"n_references":19,"next":{"headline":"Other in n/a","id":"CVE-2013-0423"},"packages":[],"prev":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2013-0421"},"products":["n/a"],"published":"2013-01-10","related":[{"cvss_score":9.8,"headline":"SaltStack Salt Authentication Bypass","id":"CVE-2020-11651","kev_date_added":"2021-11-03","published":"2020-04-30"},{"cvss_score":9.8,"headline":"OpenSMTPD Remote Code Execution","id":"CVE-2020-7247","kev_date_added":"2022-03-25","published":"2020-01-29"},{"cvss_score":9.8,"headline":"Exim Out-of-bounds Write","id":"CVE-2019-16928","kev_date_added":"2022-03-03","published":"2019-09-27"},{"cvss_score":9.8,"headline":"Exim Buffer Overflow","id":"CVE-2018-6789","kev_date_added":"2021-11-03","published":"2018-02-08"},{"cvss_score":9.8,"headline":"Oracle Java SE and Java SE Embedded Remote Code Execution","id":"CVE-2015-2590","kev_date_added":"2022-03-03","published":"2015-07-16"},{"cvss_score":9.8,"headline":"Oracle Java SE Runtime Environment (JRE) Arbitrary Code Execution","id":"CVE-2011-3544","kev_date_added":"2022-03-03","published":"2011-10-19"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"open","licence":"CC0 1.0","name":"CISA KEV"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"attribution","licence":"BSD-3-Clause","name":"Metasploit"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":"yes","exploitation":"active","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-10-22","vendors":["n/a"]},"summary":"Remote attackers can execute arbitrary code by bypassing Java security checks via JMX and Reflection API flaws, requiring an upgrade to Java 7 Update 11.","url":"https://insights.sbomify.com/CVE-2013-0422/"}
