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-1999-0160 in the wild and no public exploit code.\n\nAffected product: Cisco Ios. 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-1999-0160/ (Markdown: https://insights.sbomify.com/CVE-1999-0160/index.md)","id":"CVE-1999-0160","markdown":"https://insights.sbomify.com/CVE-1999-0160/index.md","name":"CVE-1999-0160","record":{"aliases":["GHSA-rx39-mff5-f3vv"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["security_bypass","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco IOS router","requires_auth":"none","summary":"Attackers can bypass PPP CHAP authentication to establish unauthorized connections on Cisco IOS devices.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ios","vendor":"cisco"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"AV:N/AC:L/Au:N/C:P/I:P/A:P","version":"2.0"},"cwes":[],"description":"Some classic Cisco IOS devices have a vulnerability in the PPP CHAP authentication to establish unauthorized PPP connections.","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":"Auth bypass in n/a","id":"CVE-1999-0160","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:ios","products":["cisco:ios"],"type":"auth_bypass","year":"1999"},"n_packages":0,"n_references":1,"next":{"headline":"Security feature bypass in n/a","id":"CVE-1999-0161"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-1999-0159"},"products":["n/a"],"published":"1999-09-29","related":[{"cvss_score":9.8,"headline":"Cisco IOS and IOS XE Software DHCP Remote Code Execution","id":"CVE-2017-12240","kev_date_added":"2022-03-03","published":"2017-09-28"},{"cvss_score":9.8,"headline":"Cisco IOS and IOS XE Remote Code Execution","id":"CVE-2017-3881","kev_date_added":"2022-03-25","published":"2017-03-17"},{"cvss_score":8.8,"headline":"Cisco IOS, XR, and XE Software Buffer Overflow","id":"CVE-2018-0167","kev_date_added":"2022-03-03","published":"2018-03-28"},{"cvss_score":8.8,"headline":"Cisco IOS and IOS XE Software SNMP Remote Code Execution","id":"CVE-2017-6736","kev_date_added":"2022-03-03","published":"2017-07-17"},{"cvss_score":8.8,"headline":"Cisco IOS and IOS XE Software SNMP Remote Code Execution","id":"CVE-2017-6737","kev_date_added":"2022-03-03","published":"2017-07-17"},{"cvss_score":8.8,"headline":"Cisco IOS and IOS XE Software SNMP Remote Code Execution","id":"CVE-2017-6738","kev_date_added":"2022-03-03","published":"2017-07-17"},{"cvss_score":8.8,"headline":"Cisco IOS and IOS XE Software SNMP Remote Code Execution","id":"CVE-2017-6739","kev_date_added":"2022-03-03","published":"2017-07-17"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-01","vendors":["n/a"]},"summary":"Attackers can bypass PPP CHAP authentication to establish unauthorized connections on Cisco IOS devices.","url":"https://insights.sbomify.com/CVE-1999-0160/"}
