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-2023-52428 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- com.nimbusds:nimbus-jose-jwt (Maven): affected all versions; fixed in 9.37.2\n- com.nimbusds:nimbus-jose-jwt (Maven): affected all versions; fixed in 9.37.2\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-2023-52428/ (Markdown: https://insights.sbomify.com/CVE-2023-52428/index.md)","id":"CVE-2023-52428","markdown":"https://insights.sbomify.com/CVE-2023-52428/index.md","name":"CVE-2023-52428","record":{"aliases":["CLEANSTART-2026-CO70761","CLEANSTART-2026-PS45852","CLEANSTART-2026-ZP61425","CLSA-2024-1723507378","CLSA-2024-1733443230","CLSA-2026-1778633125","CLSA-2026-1780966316","ECHO-e311-61b2-06ba","GHSA-gvpg-vgmx-xg6w","MINI-393q-rj29-63jj","MINI-3r3v-5w7w-qvh9","MINI-8p3r-jq4c-v7px","MINI-f3f9-p6fh-39f8","MINI-g98j-rvxq-7mg4","MINI-gjxh-3433-8vx8","MINI-mhqx-w394-7x97","MINI-p64x-mf7f-2vhr","RHLW-2026-0a6fc4430620d7b4","ROOT-APP-MAVEN-CVE-2023-52428"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Java JWT library","requires_auth":"none","summary":"An attacker can cause denial of service via resource consumption by sending a large JWE p2c header value to the Connect2id Nimbus JOSE+JWT library.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"nimbus_jose\\+jwt","vendor":"connect2id"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"In Connect2id Nimbus JOSE+JWT before 9.37.2, an attacker can cause a denial of service (resource consumption) via a large JWE p2c header value (aka iteration count) for the PasswordBasedDecrypter (PBKDF2) component.","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":"Denial of Service in Connect2id Nimbus JOSE+JWT","id":"CVE-2023-52428","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"denial_of_service","year":"2023"},"n_packages":2,"n_references":3,"next":{"headline":"Integer overflow in n/a","id":"CVE-2023-52429"},"packages":[{"ecosystem":"Maven","fixed":["9.37.2"],"introduced":["0"],"last_affected":[],"package":"com.nimbusds:nimbus-jose-jwt","purl":null,"source":"GHSA-gvpg-vgmx-xg6w"},{"ecosystem":"Maven","fixed":["9.37.2"],"introduced":["0"],"last_affected":[],"package":"com.nimbusds:nimbus-jose-jwt","purl":"pkg:maven/com.nimbusds/nimbus-jose-jwt","source":"GHSA-gvpg-vgmx-xg6w"}],"prev":{"headline":"Denial of service in n/a","id":"CVE-2023-52427"},"products":["n/a"],"published":"2024-02-11","related":[{"cvss_score":7.5,"headline":"Nimbus JOSE+JWT missing overflow check","id":"CVE-2017-12972","kev_date_added":null,"published":"2017-08-20"},{"cvss_score":7.5,"headline":"Improper Verification of Cryptographic Signature in Nimbus JOSE+JWT","id":"CVE-2017-12974","kev_date_added":null,"published":"2017-08-20"},{"cvss_score":3.1,"headline":"Nimbus JOSE+JWT vulnerable to padding oracle attack","id":"CVE-2017-12973","kev_date_added":null,"published":"2017-08-20"}],"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-10-30","vendors":["n/a"]},"summary":"An attacker can cause denial of service via resource consumption by sending a large JWE p2c header value to the Connect2id Nimbus JOSE+JWT library.","url":"https://insights.sbomify.com/CVE-2023-52428/"}
