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-2022-20704 in the wild and no public exploit code.\n\nAffected product: Cisco Small Business RV Series Router Firmware. 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-2022-20704/ (Markdown: https://insights.sbomify.com/CVE-2022-20704/index.md)","id":"CVE-2022-20704","markdown":"https://insights.sbomify.com/CVE-2022-20704/index.md","name":"CVE-2022-20704","record":{"aliases":["GHSA-h4rm-q6r7-j2xh"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Small Business Router","requires_auth":"none","summary":"Memory corruption flaws in Cisco Small Business RV Series Routers allow attackers to execute arbitrary code and elevate privileges.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"rv160_firmware","vendor":"cisco"},{"product":"rv160w_firmware","vendor":"cisco"},{"product":"rv260_firmware","vendor":"cisco"},{"product":"rv260p_firmware","vendor":"cisco"},{"product":"rv260w_firmware","vendor":"cisco"},{"product":"rv340_firmware","vendor":"cisco"},{"product":"rv340w_firmware","vendor":"cisco"},{"product":"rv345_firmware","vendor":"cisco"},{"product":"rv345p_firmware","vendor":"cisco"}],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"Multiple vulnerabilities in Cisco Small Business RV160, RV260, RV340, and RV345 Series Routers could allow an attacker to do any of the following: Execute arbitrary code Elevate privileges Execute arbitrary commands Bypass authentication and authorization protections Fetch and run unsigned software Cause denial of service (DoS) For more information about these vulnerabilities, see the Details section of this advisory.","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":"Cisco Small Business RV Series Routers Vulnerabilities","id":"CVE-2022-20704","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2022"},"n_packages":0,"n_references":2,"next":{"headline":"Cisco Small Business RV Series Routers Vulnerabilities","id":"CVE-2022-20705"},"packages":[],"prev":{"headline":"Cisco Small Business RV Series Routers Stack-based Buffer Overflow","id":"CVE-2022-20703"},"products":["Cisco Small Business RV Series Router Firmware"],"published":"2022-02-10","related":[{"cvss_score":10,"headline":"Cisco Small Business RV Series Routers Stack-based Buffer Overflow","id":"CVE-2022-20700","kev_date_added":"2022-03-03","published":"2022-02-10"},{"cvss_score":10,"headline":"Cisco Small Business RV Series Routers Stack-based Buffer Overflow","id":"CVE-2022-20703","kev_date_added":"2022-03-03","published":"2022-02-10"},{"cvss_score":10,"headline":"Cisco Small Business RV Series Routers Vulnerabilities","id":"CVE-2022-20702","kev_date_added":null,"published":"2022-02-10"},{"cvss_score":10,"headline":"Cisco Small Business RV Series Routers Vulnerabilities","id":"CVE-2022-20705","kev_date_added":null,"published":"2022-02-10"},{"cvss_score":10,"headline":"Cisco Small Business RV Series Routers Vulnerabilities","id":"CVE-2022-20706","kev_date_added":null,"published":"2022-02-10"},{"cvss_score":9,"headline":"Cisco Small Business RV Series Routers Vulnerabilities","id":"CVE-2022-20827","kev_date_added":null,"published":"2022-08-10"}],"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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-11-06","vendors":["Cisco"]},"summary":"Memory corruption flaws in Cisco Small Business RV Series Routers allow attackers to execute arbitrary code and elevate privileges.","url":"https://insights.sbomify.com/CVE-2022-20704/"}
