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-2009-4501 exists.\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-2009-4501/ (Markdown: https://insights.sbomify.com/CVE-2009-4501/index.md)","id":"CVE-2009-4501","markdown":"https://insights.sbomify.com/CVE-2009-4501/index.md","name":"CVE-2009-4501","record":{"aliases":["DEBIAN-CVE-2009-4501","GHSA-m4jh-qvf3-23v6"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Zabbix Server","requires_auth":"none","summary":"Remote attackers can crash Zabbix Server by sending requests with missing separators, causing a null pointer dereference.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"zabbix","vendor":"zabbix"}],"cvss":{"score":5,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:N/C:N/I:N/A:P","version":"2.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"The zbx_get_next_field function in libs/zbxcommon/str.c in Zabbix Server before 1.6.8 allows remote attackers to cause a denial of service (crash) via a request that lacks expected separators, which triggers a NULL pointer dereference, as demonstrated using the Command keyword.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2009-12-14","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2009-12-14","kind":"exploitdb","ref":"10432","stars":null,"title":"Zabbix Server - Multiple Vulnerabilities"}],"tier":"weaponised"},"has_fix":true,"headline":"Null dereference in n/a","id":"CVE-2009-4501","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"zabbix:zabbix","products":["zabbix:zabbix"],"type":"null_dereference","year":"2009"},"n_packages":0,"n_references":4,"next":{"headline":"Command injection in n/a","id":"CVE-2009-4502"},"packages":[],"prev":{"headline":"Null dereference in n/a","id":"CVE-2009-4500"},"products":["n/a"],"published":"2009-12-31","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)"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-17","vendors":["n/a"]},"summary":"Remote attackers can crash Zabbix Server by sending requests with missing separators, causing a null pointer dereference.","url":"https://insights.sbomify.com/CVE-2009-4501/"}
