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-2018-5764 in the wild and no public exploit code.\n\nAffected product: Canonical Ubuntu Linux. 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-2018-5764/ (Markdown: https://insights.sbomify.com/CVE-2018-5764/index.md)","id":"CVE-2018-5764","markdown":"https://insights.sbomify.com/CVE-2018-5764/index.md","name":"CVE-2018-5764","record":{"aliases":["ALPINE-CVE-2018-5764","DEBIAN-CVE-2018-5764","DLA-1247-1","DLA-2833-1","GHSA-qp2v-jrh4-vgj2","MGASA-2018-0103","SUSE-SU-2018:0172-1","SUSE-SU-2018:0174-1","UBUNTU-CVE-2018-5764"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"rsync file transfer","requires_auth":"none","summary":"Remote attackers can bypass argument sanitization in rsyncd by using multiple --protect-args flags, potentially exposing sensitive data or enabling further attacks.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"debian_linux","vendor":"debian"},{"product":"rsync","vendor":"samba"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[],"description":"The parse_arguments function in options.c in rsyncd in rsync before 3.1.3 does not prevent multiple --protect-args uses, which allows remote attackers to bypass an argument-sanitization protection mechanism.","ecosystems":["SUSE:Linux Enterprise Desktop 12 SP2","SUSE:Linux Enterprise Desktop 12 SP3","SUSE:Linux Enterprise Server 11 SP4","SUSE:Linux Enterprise Server 12 SP2","SUSE:Linux Enterprise Server 12 SP3","SUSE:Linux Enterprise Server for Raspberry Pi 12 SP2","SUSE:Linux Enterprise Server for SAP Applications 11 SP4","SUSE:Linux Enterprise Server for SAP Applications 12 SP2","SUSE:Linux Enterprise Server for SAP Applications 12 SP3"],"exploits":{"exploitdb":0,"first_seen":"2025-09-10","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2025-09-10T09:14:54Z","kind":"github_poc","ref":"https://github.com/waleedadam360-web/SyncShield","stars":0,"title":"SyncShield -
