An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2019-1830 in the wild and no public exploit code.\n\nAffected product: Cisco Wireless Lan Controller Software. 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-2019-1830/ (Markdown: https://insights.sbomify.com/CVE-2019-1830/index.md)","id":"CVE-2019-1830","markdown":"https://insights.sbomify.com/CVE-2019-1830/index.md","name":"CVE-2019-1830","record":{"aliases":["GHSA-w2qg-wq7x-rcmg"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Wireless LAN Controller","requires_auth":"high_privilege","summary":"An authenticated administrator can cause a denial of service on Cisco Wireless LAN Controllers by configuring a malicious Locally Significant Certificate URL.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"wireless_lan_controller_software","vendor":"cisco"}],"cvss":{"score":4.9,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"A vulnerability in Locally Significant Certificate (LSC) management for the Cisco Wireless LAN Controller (WLC) could allow an authenticated, remote attacker to cause the device to unexpectedly restart, which causes a denial of service (DoS) condition. The attacker would need to have valid administrator credentials. The vulnerability is due to incorrect input validation of the HTTP URL used to establish a connection to the LSC Certificate Authority (CA). An attacker could exploit this vulnerability by authenticating to the targeted device and configuring a LSC certificate. An exploit could allow the attacker to cause a DoS condition due to an unexpected restart of the device.","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 Wireless LAN Controller Locally Significant Certificate Denial of Service Vulnerability","id":"CVE-2019-1830","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:wireless_lan_controller_software","products":["cisco:wireless_lan_controller_software"],"type":"denial_of_service","year":"2019"},"n_packages":0,"n_references":2,"next":{"headline":"Cisco Email Security Appliance Content Filter Bypass Vulnerability","id":"CVE-2019-1831"},"packages":[],"prev":{"headline":"Cisco Aironet Series Access Points Command Injection Vulnerability","id":"CVE-2019-1829"},"products":["Cisco Wireless LAN Controller (WLC)"],"published":"2019-04-18","related":[{"cvss_score":10,"headline":"Hardcoded credentials in n/a","id":"CVE-2007-2036","kev_date_added":null,"published":"2007-04-16"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2016-1363","kev_date_added":null,"published":"2016-04-21"},{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2015-6314","kev_date_added":null,"published":"2016-01-15"},{"cvss_score":9,"headline":"Privilege escalation in n/a","id":"CVE-2010-2842","kev_date_added":null,"published":"2010-09-10"},{"cvss_score":9,"headline":"Privilege escalation in n/a","id":"CVE-2010-2843","kev_date_added":null,"published":"2010-09-10"},{"cvss_score":9,"headline":"Privilege escalation in n/a","id":"CVE-2010-3033","kev_date_added":null,"published":"2010-09-10"},{"cvss_score":8.6,"headline":"Denial of service in Cisco Wireless LAN Controller (WLC)","id":"CVE-2018-0443","kev_date_added":null,"published":"2018-10-17"}],"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":"partial"},"state":"PUBLISHED","updated":"2024-11-21","vendors":["Cisco"]},"summary":"An authenticated administrator can cause a denial of service on Cisco Wireless LAN Controllers by configuring a malicious Locally Significant Certificate URL.","url":"https://insights.sbomify.com/CVE-2019-1830/"}
