An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-3286 in the wild and no public exploit code.\n\nAffected product: Cisco Rv320 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-2020-3286/ (Markdown: https://insights.sbomify.com/CVE-2020-3286/index.md)","id":"CVE-2020-3286","markdown":"https://insights.sbomify.com/CVE-2020-3286/index.md","name":"CVE-2020-3286","record":{"aliases":["GHSA-2gqf-hxr7-jh68"],"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":"high_privilege","summary":"Authenticated administrators can trigger stack overflows in the web interface to execute arbitrary code with root privileges on Cisco Small Business routers.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"rv016_firmware","vendor":"cisco"},{"product":"rv042_firmware","vendor":"cisco"},{"product":"rv042g_firmware","vendor":"cisco"},{"product":"rv082_firmware","vendor":"cisco"},{"product":"rv320_firmware","vendor":"cisco"},{"product":"rv325_firmware","vendor":"cisco"}],"cvss":{"score":7.2,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"Multiple vulnerabilities in the web-based management interface of Cisco Small Business RV320 and RV325 Series Routers and Cisco Small Business RV016, RV042, and RV082 Routers could allow an authenticated, remote attacker with administrative privileges to execute arbitrary code on an affected device. The vulnerabilities are due to insufficient boundary restrictions on user-supplied input to scripts in the web-based management interface. An attacker with administrative privileges that are sufficient to log in to the web-based management interface could exploit each vulnerability by sending crafted requests that contain overly large values to an affected device, causing a stack overflow. A successful exploit could allow the attacker to cause the device to crash or allow the attacker to execute arbitrary code with root privileges on the underlying operating system.","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 Stack Overflow Arbitrary Code Execution Vulnerabilities","id":"CVE-2020-3286","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:rv320_firmware","products":["cisco:rv320_firmware","cisco:rv325_firmware"],"type":"memory_corruption","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco Small Business RV Series Routers Stack Overflow Arbitrary Code Execution Vulnerabilities","id":"CVE-2020-3287"},"packages":[],"prev":{"headline":"Cisco Firepower Threat Defense Software SSL/TLS URL Category Bypass Vulnerability","id":"CVE-2020-3285"},"products":["Cisco Small Business RV Series Router Firmware"],"published":"2020-06-18","related":[{"cvss_score":6.5,"headline":"Cisco Small Business RV Series Routers Command Injection","id":"CVE-2023-20118","kev_date_added":"2025-03-03","published":"2023-04-05"},{"cvss_score":9,"headline":"Auth bypass in Cisco Small Business RV Series Router Firmware","id":"CVE-2023-20025","kev_date_added":null,"published":"2023-01-19"},{"cvss_score":7.2,"headline":"Cisco Small Business RV Series Routers Command Injection Vulnerabilities","id":"CVE-2020-3274","kev_date_added":null,"published":"2020-06-18"},{"cvss_score":7.2,"headline":"Cisco Small Business RV Series Routers Command Injection Vulnerabilities","id":"CVE-2020-3275","kev_date_added":null,"published":"2020-06-18"},{"cvss_score":7.2,"headline":"Cisco Small Business RV Series Routers Command Injection Vulnerabilities","id":"CVE-2020-3276","kev_date_added":null,"published":"2020-06-18"},{"cvss_score":7.2,"headline":"Cisco Small Business RV Series Routers Command Injection Vulnerabilities","id":"CVE-2020-3277","kev_date_added":null,"published":"2020-06-18"},{"cvss_score":7.2,"headline":"Cisco Small Business RV Series Routers Command Injection Vulnerabilities","id":"CVE-2020-3278","kev_date_added":null,"published":"2020-06-18"}],"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":"total"},"state":"PUBLISHED","updated":"2024-11-15","vendors":["Cisco"]},"summary":"Authenticated administrators can trigger stack overflows in the web interface to execute arbitrary code with root privileges on Cisco Small Business routers.","url":"https://insights.sbomify.com/CVE-2020-3286/"}
