An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of GHSA-mmwx-rj87-vfgr in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- dnsjava:dnsjava (Maven): affected from 3.5.0; fixed in 3.6.0\n- dnsjava:dnsjava (Maven): affected from 3.5.0; fixed in 3.6.0\n- org.jitsi:dnssecjava (Maven): affected all versions up to 2.0.0; no fix listed\n- org.jitsi:dnssecjava (Maven): affected all versions up to 2.0.0; no fix listed\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/GHSA-mmwx-rj87-vfgr/ (Markdown: https://insights.sbomify.com/GHSA-mmwx-rj87-vfgr/index.md)","id":"GHSA-mmwx-rj87-vfgr","markdown":"https://insights.sbomify.com/GHSA-mmwx-rj87-vfgr/index.md","name":"GHSA-mmwx-rj87-vfgr","record":{"aliases":[],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Java DNS library","requires_auth":"none","summary":"Attackers can cause CPU exhaustion in applications using dnsjava's ValidatingResolver by sending specially crafted DNSSEC responses.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"### Impact\nUsers using the `ValidatingResolver` for DNSSEC validation can run into CPU exhaustion with specially crafted DNSSEC-signed zones.\n\n### Patches\nUsers should upgrade to dnsjava v3.6.0\n\n### Workarounds\nAlthough not recommended, only using a non-validating resolver, will remove the vulnerability.\n\n### References\nhttps://www.athene-center.de/en/keytrap","ecosystems":["Maven"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":true,"headline":"DNSJava affected by KeyTrap - NSEC3 closest encloser proof can exhaust CPU resources","id":"GHSA-mmwx-rj87-vfgr","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":"Maven","product":null,"products":[],"type":"denial_of_service","year":"2024"},"n_packages":4,"n_references":null,"packages":[{"ecosystem":"Maven","fixed":["3.6.0"],"introduced":["3.5.0"],"last_affected":[],"package":"dnsjava:dnsjava","purl":null,"source":"GHSA-mmwx-rj87-vfgr"},{"ecosystem":"Maven","fixed":["3.6.0"],"introduced":["3.5.0"],"last_affected":[],"package":"dnsjava:dnsjava","purl":"pkg:maven/dnsjava/dnsjava","source":"GHSA-mmwx-rj87-vfgr"},{"ecosystem":"Maven","fixed":[],"introduced":["0"],"last_affected":["2.0.0"],"package":"org.jitsi:dnssecjava","purl":null,"source":"GHSA-mmwx-rj87-vfgr"},{"ecosystem":"Maven","fixed":[],"introduced":["0"],"last_affected":["2.0.0"],"package":"org.jitsi:dnssecjava","purl":"pkg:maven/org.jitsi/dnssecjava","source":"GHSA-mmwx-rj87-vfgr"}],"products":null,"published":"2024-07-22","related":[],"sources":[{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":"Attackers can cause CPU exhaustion in applications using dnsjava's ValidatingResolver by sending specially crafted DNSSEC responses.","url":"https://insights.sbomify.com/GHSA-mmwx-rj87-vfgr/"}
