An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-36938 in the wild and no public exploit code.\n\nAffected product: Facebook Redex. 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-2022-36938/ (Markdown: https://insights.sbomify.com/CVE-2022-36938/index.md)","id":"CVE-2022-36938","markdown":"https://insights.sbomify.com/CVE-2022-36938/index.md","name":"CVE-2022-36938","record":{"aliases":["GHSA-2prh-76mq-h4gx"],"analysis":{"component_type":"developer_tool","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Android APK optimizer","requires_auth":"none","summary":"An out-of-bounds read in Redex's DexLoader allows remote code execution when processing malicious Android APK files.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"facebook","cpe":[{"product":"redex","vendor":"facebook"}],"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-1284","name":"Improper Validation of Specified Quantity in Input"},{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"DexLoader function get_stringidx_fromdex() in Redex prior to commit 3b44c64 can load an out of bound address when loading the string index table, potentially allowing remote code execution during processing of a 3rd party Android APK file.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Memory corruption in Redex","id":"CVE-2022-36938","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2022"},"n_packages":0,"n_references":1,"next":{"headline":"Path traversal in SSZipArchive","id":"CVE-2022-36943"},"packages":[],"prev":{"headline":"HHVM 4.172.0 and all prior versions use TLS 1.0 for secure connections when handling tls:// URLs in the stream extension.","id":"CVE-2022-36937"},"products":["Redex"],"published":"2022-11-10","related":[],"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":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-05-01","vendors":["Facebook"]},"summary":"An out-of-bounds read in Redex's DexLoader allows remote code execution when processing malicious Android APK files.","url":"https://insights.sbomify.com/CVE-2022-36938/"}
