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-2019-1839 in the wild and no public exploit code.\n\nAffected product: Cisco Remote PHY. 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-2019-1839/ (Markdown: https://insights.sbomify.com/CVE-2019-1839/index.md)","id":"CVE-2019-1839","markdown":"https://insights.sbomify.com/CVE-2019-1839/index.md","name":"CVE-2019-1839","record":{"aliases":["GHSA-6hf6-gmp8-5xw9"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Cisco Remote PHY","requires_auth":"high_privilege","summary":"Authenticated local attackers can execute arbitrary commands as root on Cisco Remote PHY devices due to improper input sanitization.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"cbr-8_firmware","vendor":"cisco"},{"product":"remote_phy_120_firmware","vendor":"cisco"},{"product":"remote_phy_220_firmware","vendor":"cisco"},{"product":"remote_phy_shelf_7200_firmware","vendor":"cisco"}],"cvss":{"score":6.7,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"},{"id":"CWE-20","name":"Improper Input Validation"}],"description":"A vulnerability in Cisco Remote PHY Device Software could allow an authenticated, local attacker to execute commands on the underlying Linux shell of an affected device with root privileges. The vulnerability occurs because the affected software improperly sanitizes user-supplied input. An attacker who has valid administrator access to an affected device could exploit this vulnerability by supplying various CLI commands with crafted arguments. A successful exploit could allow the attacker to run arbitrary commands as the root user, allowing complete compromise of the system.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Cisco Remote PHY Device Software Command Injection Vulnerability","id":"CVE-2019-1839","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2019"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco Prime Network Registrar Denial of Service Vulnerability","id":"CVE-2019-1840"},"packages":[],"prev":{"headline":"Cisco Application Policy Infrastructure Controller Web-Based Management Interface Cross-Site Scripting Vulnerability","id":"CVE-2019-1838"},"products":["Cisco Remote PHY"],"published":"2019-08-21","related":[],"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)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-11-20","vendors":["Cisco"]},"summary":"Authenticated local attackers can execute arbitrary commands as root on Cisco Remote PHY devices due to improper input sanitization.","url":"https://insights.sbomify.com/CVE-2019-1839/"}
