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-2021-35296 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-2021-35296/ (Markdown: https://insights.sbomify.com/CVE-2021-35296/index.md)","id":"CVE-2021-35296","markdown":"https://insights.sbomify.com/CVE-2021-35296/index.md","name":"CVE-2021-35296","record":{"aliases":["GHSA-6ff3-hggp-pc89"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"PTCL home router","requires_auth":"none","summary":"Attackers can bypass administrator authentication on PTCL HG150-Ub v3.0 routers by modifying cookie values and response paths.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"hg150-ub_firmware","vendor":"ptcl"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"An issue in the administrator authentication panel of PTCL HG150-Ub v3.0 allows attackers to bypass authentication via modification of the cookie value and Response Path.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2021-09-30","github_poc":1,"max_poc_stars":2,"metasploit":0,"nuclei":0,"refs":[{"date":"2021-09-30T18:18:27Z","kind":"github_poc","ref":"https://github.com/afaq1337/CVE-2021-35296","stars":2,"title":"PoC of CVE-2021-35296 - PTCL Modem HG150-Ub"}],"tier":"poc_unverified"},"has_fix":null,"headline":"Auth bypass in n/a","id":"CVE-2021-35296","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in n/a","id":"CVE-2021-35297"},"packages":[],"prev":{"headline":"File upload in n/a","id":"CVE-2021-35290"},"products":["n/a"],"published":"2021-10-04","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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Attackers can bypass administrator authentication on PTCL HG150-Ub v3.0 routers by modifying cookie values and response paths.","url":"https://insights.sbomify.com/CVE-2021-35296/"}
