An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-46427 exists.\n\nAffected product: Gpac Gpac. 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-2023-46427/ (Markdown: https://insights.sbomify.com/CVE-2023-46427/index.md)","id":"CVE-2023-46427","markdown":"https://insights.sbomify.com/CVE-2023-46427/index.md","name":"CVE-2023-46427","record":{"aliases":["DEBIAN-CVE-2023-46427","GHSA-q8g7-2p5j-49jv","UBUNTU-CVE-2023-46427"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"GPAC media library","requires_auth":"none","summary":"Remote attackers can execute arbitrary code, cause denial of service, or read sensitive information via a null pointer dereference in GPAC.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"gpac","vendor":"gpac"}],"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-476","name":"NULL Pointer Dereference"}],"description":"An issue was discovered in gpac version 2.3-DEV-rev588-g7edc40fee-master, allows remote attackers to execute arbitrary code, cause a denial of service (DoS), and obtain sensitive information via null pointer deference in gf_dash_setup_period component in media_tools/dash_client.c.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"Null dereference in n/a","id":"CVE-2023-46427","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"gpac:gpac","products":["gpac:gpac"],"type":"null_dereference","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"File upload in n/a","id":"CVE-2023-46428"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2023-46426"},"products":["n/a"],"published":"2024-03-09","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2023-46932","kev_date_added":null,"published":"2023-12-09"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2022-36190","kev_date_added":null,"published":"2022-08-17"},{"cvss_score":9.8,"headline":"Null dereference in n/a","id":"CVE-2021-28300","kev_date_added":null,"published":"2021-04-14"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2020-11558","kev_date_added":null,"published":"2020-04-05"},{"cvss_score":9.1,"headline":"Memory corruption in n/a","id":"CVE-2020-19751","kev_date_added":null,"published":"2021-09-07"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2023-46426","kev_date_added":null,"published":"2024-03-09"}],"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":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-08-28","vendors":["n/a"]},"summary":"Remote attackers can execute arbitrary code, cause denial of service, or read sensitive information via a null pointer dereference in GPAC.","url":"https://insights.sbomify.com/CVE-2023-46427/"}
