It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-49643 in the wild and no public exploit code.\n\nAffected product: 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-2025-49643/ (Markdown: https://insights.sbomify.com/CVE-2025-49643/index.md)","id":"CVE-2025-49643","markdown":"https://insights.sbomify.com/CVE-2025-49643/index.md","name":"CVE-2025-49643","record":{"aliases":["DEBIAN-CVE-2025-49643","GHSA-728r-qj99-48p2","UBUNTU-CVE-2025-49643"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Zabbix monitoring system","requires_auth":"none","summary":"An authenticated Zabbix user can cause server CPU exhaustion via crafted requests to imgstore.php, leading to denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Zabbix","cpe":[{"product":"frontend","vendor":"zabbix"}],"cvss":{"score":6,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:A/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-405","name":"Asymmetric Resource Consumption (Amplification)"}],"description":"An authenticated Zabbix user (including Guest) is able to cause disproportionate CPU load on the webserver by sending specially crafted parameters to /imgstore.php, leading to potential denial of service.","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":"Frontend DoS vulnerability due to asymmetric resource consumption","id":"CVE-2025-49643","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Missing Authorization for Interactive Sessions","id":"CVE-2025-49651"},"packages":[],"prev":{"headline":"Agent builds for AIX vulnerable to library loading hijacking","id":"CVE-2025-49642"},"products":["Zabbix"],"published":"2025-12-01","related":[{"cvss_score":9.6,"headline":"Leak of zbx_session cookie when using a scheduled report that includes a dashboard with a URL widget.","id":"CVE-2023-32725","kev_date_added":null,"published":"2023-12-18"},{"cvss_score":6.8,"headline":"Frontend arbitrary file read in oauth.authorize action","id":"CVE-2025-27232","kev_date_added":null,"published":"2025-12-01"},{"cvss_score":6.3,"headline":"Insufficient validation of Action form input fields","id":"CVE-2023-29457","kev_date_added":null,"published":"2023-07-13"},{"cvss_score":5.7,"headline":"Inefficient URL schema validation","id":"CVE-2023-29456","kev_date_added":null,"published":"2023-07-13"},{"cvss_score":5.4,"headline":"Persistent XSS in the user form","id":"CVE-2023-29454","kev_date_added":null,"published":"2023-07-13"},{"cvss_score":5.4,"headline":"Reflected XSS in several fields of graph form","id":"CVE-2023-29455","kev_date_added":null,"published":"2023-07-13"}],"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":"2025-12-01","vendors":["Zabbix"]},"summary":"An authenticated Zabbix user can cause server CPU exhaustion via crafted requests to imgstore.php, leading to denial of service.","url":"https://insights.sbomify.com/CVE-2025-49643/"}
