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-2024-45244 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/hyperledger/fabric (Go): affected all versions; no fix listed\n- github.com/hyperledger/fabric (Go): affected all versions up to 2.5.9; no fix listed\n- github.com/hyperledger/fabric (Go): affected all versions up to 2.5.9; no fix listed\n- hyperledger-fabric-orderer (Bitnami): affected all versions; fixed in 2.5.10\n- hyperledger-fabric-peer (Bitnami): affected all versions; fixed in 2.5.10\n- hyperledger-fabric-tools (Bitnami): affected all versions; fixed in 2.5.10\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-2024-45244/ (Markdown: https://insights.sbomify.com/CVE-2024-45244/index.md)","id":"CVE-2024-45244","markdown":"https://insights.sbomify.com/CVE-2024-45244/index.md","name":"CVE-2024-45244","record":{"aliases":["BIT-hyperledger-fabric-orderer-2024-45244","BIT-hyperledger-fabric-peer-2024-45244","BIT-hyperledger-fabric-tools-2024-45244","GHSA-48gg-32q2-4r6m","GO-2024-3099"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Hyperledger Fabric","requires_auth":"none","summary":"Attackers can bypass timestamp verification in Hyperledger Fabric, potentially replaying requests or manipulating transaction ordering.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"fabric","vendor":"hyperledger"}],"cvss":{"score":5.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-294","name":"Authentication Bypass by Capture-replay"}],"description":"Hyperledger Fabric through 3.0.0 and 2.5.x through 2.5.9 do not verify that a request has a timestamp within the expected time window.","ecosystems":["Bitnami","Go"],"exploits":{"exploitdb":0,"first_seen":"2024-06-23","github_poc":2,"max_poc_stars":3,"metasploit":0,"nuclei":0,"refs":[{"date":"2024-07-28T19:19:42Z","kind":"github_poc","ref":"https://github.com/shanker-sec/hlf-time-oracle","stars":3,"title":"Chaincode for blockchain Hyperledger Fabric provides accurate time to other chaincodes.
