Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-12773 in the wild and no public exploit code.\n\nAffected product: Realtek ADSL/PON Modem SoC. 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-2020-12773/ (Markdown: https://insights.sbomify.com/CVE-2020-12773/index.md)","id":"CVE-2020-12773","markdown":"https://insights.sbomify.com/CVE-2020-12773/index.md","name":"CVE-2020-12773","record":{"aliases":["GHSA-wmgf-fhc9-5pvg"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Realtek Modem SoC","requires_auth":"low_privilege","summary":"Attackers can execute arbitrary commands remotely on Realtek ADSL/PON Modem SoC firmware by exploiting a default password in the network monitoring tool.","user_interaction":"not_required","vuln_class":"hardcoded_credentials"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"twcert","cpe":[{"product":"adsl_router_soc_firmware","vendor":"realtek"}],"cvss":{"score":9.6,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N","version":"3.1"},"cwes":[],"description":"A security misconfiguration vulnerability exists in the SDK of some Realtek ADSL/PON Modem SoC firmware, which allows attackers using a default password to execute arbitrary commands remotely via the build-in network monitoring tool.","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":"Realtek ADSL/PON Modem SoC - Security Misconfiguration","id":"CVE-2020-12773","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"hardcoded_credentials","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"D-Link DSL-7740C - Command Injection","id":"CVE-2020-12774"},"packages":[],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2020-12772"},"products":["ADSL/PON Modem SoC"],"published":"2020-06-08","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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-17","vendors":["Realtek"]},"summary":"Attackers can execute arbitrary commands remotely on Realtek ADSL/PON Modem SoC firmware by exploiting a default password in the network monitoring tool.","url":"https://insights.sbomify.com/CVE-2020-12773/"}
