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-2020-10136 in the wild and no public exploit code.\n\nAffected product: Cisco Nx-Os. 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-2020-10136/ (Markdown: https://insights.sbomify.com/CVE-2020-10136/index.md)","id":"CVE-2020-10136","markdown":"https://insights.sbomify.com/CVE-2020-10136/index.md","name":"CVE-2020-10136","record":{"aliases":["GHSA-8gxc-83hw-9578"],"analysis":{"component_type":"operating_system","fix_type":"configuration_change","impacts":["security_bypass","other"],"network_reachable":"yes","non_default_config":false,"product_category":"IP-in-IP protocol","requires_auth":"none","summary":"Remote attackers can bypass access controls and route arbitrary traffic by exploiting IP-in-IP encapsulation flaws, affecting systems with this protocol enabled.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"certcc","cpe":[{"product":"nx-os","vendor":"cisco"},{"product":"ucs_manager","vendor":"cisco"},{"product":"unified_computing_system","vendor":"cisco"},{"product":"saros","vendor":"digi"},{"product":"x3220nr_firmware","vendor":"hp"},{"product":"tcp\\/ip","vendor":"treck"}],"cvss":{"score":5.3,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-290","name":"Authentication Bypass by Spoofing"}],"description":"IP-in-IP protocol specifies IP Encapsulation within IP standard (RFC 2003, STD 1) that decapsulate and route IP-in-IP traffic is vulnerable to spoofing, access-control bypass and other unexpected behavior due to the lack of validation to verify network packets before decapsulation and routing.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2025-01-21","github_poc":1,"max_poc_stars":12,"metasploit":0,"nuclei":0,"refs":[{"date":"2025-01-21T19:41:35Z","kind":"github_poc","ref":"https://github.com/PapayaJackal/ipeeyoupeewepee","stars":12,"title":"Scanner and attack suite for hosts that forward unauthenticated packets via IPIP and GRE protocols.
