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-2023-4043 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.eclipse.parsson:project (Maven): affected all versions; fixed in 1.0.5\n- org.eclipse.parsson:project (Maven): affected all versions; fixed in 1.0.5\n- org.eclipse.parsson:project (Maven): affected from 1.1.0; fixed in 1.1.4\n- org.eclipse.parsson:project (Maven): affected from 1.1.0; fixed in 1.1.4\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-2023-4043/ (Markdown: https://insights.sbomify.com/CVE-2023-4043/index.md)","id":"CVE-2023-4043","markdown":"https://insights.sbomify.com/CVE-2023-4043/index.md","name":"CVE-2023-4043","record":{"aliases":["GHSA-g8p6-p27c-52fx"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Java JSON library","requires_auth":"none","summary":"Attackers can cause denial of service by sending JSON with numbers that trigger excessive processing time in the Parsson library.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"eclipse","cpe":[{"product":"parsson","vendor":"eclipse"}],"cvss":{"score":5.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-834","name":"Excessive Iteration"},{"id":"CWE-20","name":"Improper Input Validation"}],"description":"In Eclipse Parsson before versions 1.1.4 and 1.0.5, Parsing JSON from untrusted sources can lead malicious actors to exploit the fact that the built-in support for parsing numbers with large scale in Java has a number of edge cases where the input text of a number can lead to much larger processing time than one would expect.\n\nTo mitigate the risk, parsson put in place a size limit for the numbers as well as their scale.","ecosystems":["Maven"],"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":"Parsson DoS when parsing numbers from untrusted sources","id":"CVE-2023-4043","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"denial_of_service","year":"2023"},"n_packages":4,"n_references":2,"next":{"headline":"Information disclosure in Firefox","id":"CVE-2023-4045"},"packages":[{"ecosystem":"Maven","fixed":["1.0.5"],"introduced":["0"],"last_affected":[],"package":"org.eclipse.parsson:project","purl":null,"source":"GHSA-g8p6-p27c-52fx"},{"ecosystem":"Maven","fixed":["1.0.5"],"introduced":["0"],"last_affected":[],"package":"org.eclipse.parsson:project","purl":"pkg:maven/org.eclipse.parsson/project","source":"GHSA-g8p6-p27c-52fx"},{"ecosystem":"Maven","fixed":["1.1.4"],"introduced":["1.1.0"],"last_affected":[],"package":"org.eclipse.parsson:project","purl":null,"source":"GHSA-g8p6-p27c-52fx"},{"ecosystem":"Maven","fixed":["1.1.4"],"introduced":["1.1.0"],"last_affected":[],"package":"org.eclipse.parsson:project","purl":"pkg:maven/org.eclipse.parsson/project","source":"GHSA-g8p6-p27c-52fx"}],"prev":{"headline":"Ghostscript: incomplete fix for cve-2020-16305","id":"CVE-2023-4042"},"products":["Parsson"],"published":"2023-11-03","related":[{"cvss_score":8.6,"headline":"Eclipse Parsson stack overflow with deeply nested objects","id":"CVE-2023-7272","kev_date_added":null,"published":"2024-07-17"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"2024-09-05","vendors":["Eclipse Foundation"]},"summary":"Attackers can cause denial of service by sending JSON with numbers that trigger excessive processing time in the Parsson library.","url":"https://insights.sbomify.com/CVE-2023-4043/"}
