An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-20753 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-2022-20753/ (Markdown: https://insights.sbomify.com/CVE-2022-20753/index.md)","id":"CVE-2022-20753","markdown":"https://insights.sbomify.com/CVE-2022-20753/index.md","name":"CVE-2022-20753","record":{"aliases":["GHSA-x2hp-jfj2-m3hc"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Small Business Router","requires_auth":"high_privilege","summary":"An authenticated administrator can execute arbitrary code on Cisco Small Business RV Series Routers via malicious input in the web management interface.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"rv340_firmware","vendor":"cisco"},{"product":"rv340w_firmware","vendor":"cisco"},{"product":"rv345_firmware","vendor":"cisco"},{"product":"rv345p_firmware","vendor":"cisco"}],"cvss":{"score":4.7,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"A vulnerability in web-based management interface of Cisco Small Business RV340 and RV345 Routers could allow an authenticated, remote attacker to execute arbitrary code on an affected device.
