An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2017-12973 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 4.39\n- com.nimbusds:nimbus-jose-jwt (Maven): affected all versions; fixed in 4.39\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-2017-12973/ (Markdown: https://insights.sbomify.com/CVE-2017-12973/index.md)","id":"CVE-2017-12973","markdown":"https://insights.sbomify.com/CVE-2017-12973/index.md","name":"CVE-2017-12973","record":{"aliases":["GHSA-jfmq-4g4m-99rh"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Java JWT library","requires_auth":"none","summary":"Attackers can exploit a padding oracle vulnerability in Nimbus JOSE+JWT to decrypt AES-CBC data by improperly handling invalid HMACs.","user_interaction":"required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"nimbus_jose\\+jwt","vendor":"connect2id"}],"cvss":{"score":3.1,"severity":"low","source":"nvd","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N","version":"3.0"},"cwes":[{"id":"CWE-354","name":"Improper Validation of Integrity Check Value"}],"description":"Nimbus JOSE+JWT before 4.39 proceeds improperly after detection of an invalid HMAC in authenticated AES-CBC decryption, which allows attackers to conduct a padding oracle attack.","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":"Nimbus JOSE+JWT vulnerable to padding oracle attack","id":"CVE-2017-12973","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"other","year":"2017"},"n_packages":2,"n_references":3,"next":{"headline":"Improper Verification of Cryptographic Signature in Nimbus JOSE+JWT","id":"CVE-2017-12974"},"packages":[{"ecosystem":"Maven","fixed":["4.39"],"introduced":["0"],"last_affected":[],"package":"com.nimbusds:nimbus-jose-jwt","purl":null,"source":"GHSA-jfmq-4g4m-99rh"},{"ecosystem":"Maven","fixed":["4.39"],"introduced":["0"],"last_affected":[],"package":"com.nimbusds:nimbus-jose-jwt","purl":"pkg:maven/com.nimbusds/nimbus-jose-jwt","source":"GHSA-jfmq-4g4m-99rh"}],"prev":{"headline":"Nimbus JOSE+JWT missing overflow check","id":"CVE-2017-12972"},"products":["n/a"],"published":"2017-08-20","related":[{"cvss_score":7.5,"headline":"Denial of Service in Connect2id Nimbus JOSE+JWT","id":"CVE-2023-52428","kev_date_added":null,"published":"2024-02-11"},{"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"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-17","vendors":["n/a"]},"summary":"Attackers can exploit a padding oracle vulnerability in Nimbus JOSE+JWT to decrypt AES-CBC data by improperly handling invalid HMACs.","url":"https://insights.sbomify.com/CVE-2017-12973/"}
