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-2020-27636 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2020-27636/ (Markdown: https://insights.sbomify.com/CVE-2020-27636/index.md)","id":"CVE-2020-27636","markdown":"https://insights.sbomify.com/CVE-2020-27636/index.md","name":"CVE-2020-27636","record":{"aliases":["GHSA-hwcm-7pc9-m9x2"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"MPLAB Net IDE","requires_auth":"none","summary":"An attacker can predict TCP Initial Sequence Numbers in MPLAB Net, potentially allowing session hijacking or connection spoofing.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"mplab_network_creator","vendor":"microchip"}],"cvss":{"score":9.1,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-330","name":"Use of Insufficiently Random Values"}],"description":"In Microchip MPLAB Net 3.6.1, TCP ISNs are improperly random.","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":"Weak cryptography in n/a","id":"CVE-2020-27636","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"weak_cryptography","year":"2020"},"n_packages":0,"n_references":3,"next":{"headline":"Path traversal in n/a","id":"CVE-2020-27637"},"packages":[],"prev":{"headline":"Weak cryptography in n/a","id":"CVE-2020-27635"},"products":["n/a"],"published":"2023-10-10","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":"partial"},"state":"PUBLISHED","updated":"2024-09-19","vendors":["n/a"]},"summary":"An attacker can predict TCP Initial Sequence Numbers in MPLAB Net, potentially allowing session hijacking or connection spoofing.","url":"https://insights.sbomify.com/CVE-2020-27636/"}
