An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2004-0230 exists.\n\nAffected product: Juniper Junos. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2004-0230/ (Markdown: https://insights.sbomify.com/CVE-2004-0230/index.md)","id":"CVE-2004-0230","markdown":"https://insights.sbomify.com/CVE-2004-0230/index.md","name":"CVE-2004-0230","record":{"aliases":["DEBIAN-CVE-2004-0230","GHSA-58p6-7f25-xqv3","ROOT-OS-DEBIAN-12-CVE-2004-0230","ROOT-OS-DEBIAN-13-CVE-2004-0230"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel TCP","requires_auth":"none","summary":"Remote attackers can disrupt persistent TCP connections by injecting RST packets, exploiting large window sizes to guess sequence numbers.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"junos","vendor":"juniper"},{"product":"network_data_loss_prevention","vendor":"mcafee"},{"product":"windows_2000","vendor":"microsoft"},{"product":"windows_98","vendor":"microsoft"},{"product":"windows_98se","vendor":"microsoft"},{"product":"windows_server_2003","vendor":"microsoft"},{"product":"windows_xp","vendor":"microsoft"},{"product":"netbsd","vendor":"netbsd"},{"product":"openpgp","vendor":"openpgp"},{"product":"solaris","vendor":"oracle"},{"product":"openserver","vendor":"xinuos"},{"product":"unixware","vendor":"xinuos"}],"cvss":{"score":5,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:N/C:N/I:N/A:P","version":"2.0"},"cwes":[],"description":"TCP, when using a large Window Size, makes it easier for remote attackers to guess sequence numbers and cause a denial of service (connection loss) to persistent TCP connections by repeatedly injecting a TCP RST packet, especially in protocols that use long-lived connections, such as BGP.","ecosystems":[],"exploits":{"exploitdb":7,"first_seen":"2004-03-05","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2004-03-05","kind":"exploitdb","ref":"24030","stars":null,"title":"Multiple Vendor -
