An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-29451 in the wild and no public exploit code.\n\nAffected product: Zabbix Zabbix. 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-2023-29451/ (Markdown: https://insights.sbomify.com/CVE-2023-29451/index.md)","id":"CVE-2023-29451","markdown":"https://insights.sbomify.com/CVE-2023-29451/index.md","name":"CVE-2023-29451","record":{"aliases":["DEBIAN-CVE-2023-29451","GHSA-5q7w-vc8g-r5vx"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Zabbix monitoring server","requires_auth":"high_privilege","summary":"A crafted string triggers a buffer overrun in the JSON parser, crashing the Zabbix Server or Proxy.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Zabbix","cpe":[{"product":"zabbix","vendor":"zabbix"}],"cvss":{"score":4.7,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Specially crafted string can cause a buffer overrun in the JSON parser library leading to a crash of the Zabbix Server or a Zabbix Proxy.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Denial of service caused by a bug in the JSON parser","id":"CVE-2023-29451","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"zabbix:zabbix","products":["zabbix:zabbix"],"type":"denial_of_service","year":"2023"},"n_packages":0,"n_references":2,"next":{"headline":"Remove possibility to add html into Geomap attribution field","id":"CVE-2023-29452"},"packages":[],"prev":{"headline":"Unauthorized limited filesystem access from preprocessing","id":"CVE-2023-29450"},"products":["Zabbix"],"published":"2023-07-13","related":[{"cvss_score":9.1,"headline":"Zabbix Frontend Authentication Bypass","id":"CVE-2022-23131","kev_date_added":"2022-02-22","published":"2022-01-13"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2007-0640","kev_date_added":null,"published":"2007-01-31"},{"cvss_score":9.9,"headline":"SQL injection in user.get API","id":"CVE-2024-42327","kev_date_added":null,"published":"2024-11-27"},{"cvss_score":9.9,"headline":"Remote code execution within ping script","id":"CVE-2024-22116","kev_date_added":null,"published":"2024-08-09"},{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2013-3738","kev_date_added":null,"published":"2020-02-17"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2013-5743","kev_date_added":null,"published":"2019-12-11"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2016-10134","kev_date_added":null,"published":"2017-02-16"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-02-13","vendors":["Zabbix"]},"summary":"A crafted string triggers a buffer overrun in the JSON parser, crashing the Zabbix Server or Proxy.","url":"https://insights.sbomify.com/CVE-2023-29451/"}
