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-2021-45757 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-2021-45757/ (Markdown: https://insights.sbomify.com/CVE-2021-45757/index.md)","id":"CVE-2021-45757","markdown":"https://insights.sbomify.com/CVE-2021-45757/index.md","name":"CVE-2021-45757","record":{"aliases":["GHSA-fhfv-jcfj-9cg7"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"ASUS wireless router","requires_auth":"none","summary":"A buffer overflow in the blocking.cgi script of ASUS AC68U routers allows attackers to cause a denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"rt-ac68u_firmware","vendor":"asus"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"ASUS AC68U \u003c=3.0.0.4.385.20852 is affected by a buffer overflow in blocking.cgi, which may cause a denial of service (DoS).","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":"Memory corruption in n/a","id":"CVE-2021-45757","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Null dereference in n/a","id":"CVE-2021-45760"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2021-45756"},"products":["n/a"],"published":"2022-03-23","related":[{"cvss_score":9.1,"headline":"Path traversal in n/a","id":"CVE-2021-37315","kev_date_added":null,"published":"2023-02-03"},{"cvss_score":9.1,"headline":"Path traversal in n/a","id":"CVE-2021-37317","kev_date_added":null,"published":"2023-02-03"},{"cvss_score":7.5,"headline":"SQL injection in n/a","id":"CVE-2021-37316","kev_date_added":null,"published":"2023-02-03"},{"cvss_score":6.1,"headline":"Cross-site scripting in RT-AC68U","id":"CVE-2018-0582","kev_date_added":null,"published":"2018-05-14"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-07-09","vendors":["n/a"]},"summary":"A buffer overflow in the blocking.cgi script of ASUS AC68U routers allows attackers to cause a denial of service.","url":"https://insights.sbomify.com/CVE-2021-45757/"}
