It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-0438 in the wild and no public exploit code.\n\nAffected product: Cisco Umbrella. 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-2018-0438/ (Markdown: https://insights.sbomify.com/CVE-2018-0438/index.md)","id":"CVE-2018-0438","markdown":"https://insights.sbomify.com/CVE-2018-0438/index.md","name":"CVE-2018-0438","record":{"aliases":["GHSA-5jrx-2w68-hx2j"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Cisco Umbrella Roaming Client","requires_auth":"low_privilege","summary":"Local authenticated attackers can elevate privileges to Administrator by placing executables in restricted directories due to improper file system permissions.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"umbrella_enterprise_roaming_client","vendor":"cisco"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-269","name":"Improper Privilege Management"},{"id":"CWE-20","name":"Improper Input Validation"}],"description":"A vulnerability in the Cisco Umbrella Enterprise Roaming Client (ERC) could allow an authenticated, local attacker to elevate privileges to Administrator.

An attacker could exploit this vulnerability by placing an executable file within the restricted directory, which when executed by the ERC client, would run with Administrator privileges.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2018-09-06","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2018-09-06","kind":"exploitdb","ref":"45339","stars":null,"title":"Cisco Umbrella Roaming Client 2.0.168 - Local Privilege Escalation"}],"tier":"poc_unverified"},"has_fix":null,"headline":"Cisco Umbrella Enterprise Roaming Client Privilege Escalation Vulnerability","id":"CVE-2018-0438","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2018"},"n_packages":0,"n_references":3,"next":{"headline":"Cisco Meeting Server Cross-Site Request Forgery Vulnerability","id":"CVE-2018-0439"},"packages":[],"prev":{"headline":"Cisco Umbrella Enterprise Roaming Client and Enterprise Roaming Module Privilege Escalation Vulnerability","id":"CVE-2018-0437"},"products":["Cisco Umbrella"],"published":"2018-10-05","related":[{"cvss_score":7.8,"headline":"Cisco Umbrella Enterprise Roaming Client and Enterprise Roaming Module Privilege Escalation Vulnerability","id":"CVE-2018-0437","kev_date_added":null,"published":"2018-10-05"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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)"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-11-26","vendors":["Cisco"]},"summary":"Local authenticated attackers can elevate privileges to Administrator by placing executables in restricted directories due to improper file system permissions.","url":"https://insights.sbomify.com/CVE-2018-0438/"}
