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-1999-1129 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-1999-1129/ (Markdown: https://insights.sbomify.com/CVE-1999-1129/index.md)","id":"CVE-1999-1129","markdown":"https://insights.sbomify.com/CVE-1999-1129/index.md","name":"CVE-1999-1129","record":{"aliases":["GHSA-29q9-4h2h-9p7g"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Catalyst switch","requires_auth":"none","summary":"Remote attackers can inject frames into other VLANs by forging trunking tags, bypassing network segmentation on Cisco Catalyst switches.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"catalyst_2900_vlan","vendor":"cisco"},{"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":"Cisco Catalyst 2900 Virtual LAN (VLAN) switches allow remote attackers to inject 802.1q frames into another VLAN by forging the VLAN identifier in the trunking tag.","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":"Missing authorization in n/a","id":"CVE-1999-1129","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:ios","products":["cisco:ios"],"type":"missing_authorization","year":"1999"},"n_packages":0,"n_references":4,"next":{"headline":"Information disclosure in n/a","id":"CVE-1999-1130"},"packages":[],"prev":{"headline":"Internet Explorer 3.01 on Windows 95 allows remote malicious web sites to execute arbitrary commands via a .isp file, which is automatically","id":"CVE-1999-1128"},"products":["n/a"],"published":"2001-09-12","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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-01","vendors":["n/a"]},"summary":"Remote attackers can inject frames into other VLANs by forging trunking tags, bypassing network segmentation on Cisco Catalyst switches.","url":"https://insights.sbomify.com/CVE-1999-1129/"}
