An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2020-7548 and fix it if it is affected.\n\nWhat it is: CVE-2020-7548 is a critical vulnerability in Smartlink, PowerTag, and Wiser Series Gateways (see security notification for version information), published on 1 Dec 2020. 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-2020-7548 in the wild and no public exploit code.\n\nAffected product: Smartlink, PowerTag, and Wiser Series Gateways (see security notification for version information). 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-2020-7548/ (Markdown: https://insights.sbomify.com/CVE-2020-7548/index.md)","id":"CVE-2020-7548","markdown":"https://insights.sbomify.com/CVE-2020-7548/index.md","name":"CVE-2020-7548","record":{"aliases":["GHSA-hg3w-24rp-mf42"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Smartlink PowerTag Wiser Gateways","requires_auth":"none","summary":"Insufficiently random values in Smartlink, PowerTag, and Wiser Gateways allow unauthorized users to bypass authentication and log in.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"schneider","cpe":[{"product":"acti9_powertag_link_firmware","vendor":"schneider-electric"},{"product":"acti9_powertag_link_hd_firmware","vendor":"schneider-electric"},{"product":"acti9_smartlink_el_b_firmware","vendor":"schneider-electric"},{"product":"acti9_smartlink_si_b_firmware","vendor":"schneider-electric"},{"product":"acti9_smartlink_si_d_firmware","vendor":"schneider-electric"},{"product":"wiser_energy_firmware","vendor":"schneider-electric"},{"product":"wiser_link_firmware","vendor":"schneider-electric"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-330","name":"Use of Insufficiently Random Values"}],"description":"A CWE-330 - Use of Insufficiently Random Values vulnerability exists in Smartlink, PowerTag, and Wiser Series Gateways (see security notification for version information) that could allow unauthorized users to login.","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":"Weak cryptography in Smartlink, PowerTag, and Wiser Series Gateways (see security notification for version information)","id":"CVE-2020-7548","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"weak_cryptography","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Denial of service in Web Server on Modicon M340, Legacy Offers Modicon Quantum and Modicon Premium and associated Communication Modules (see security notification for affected versions)","id":"CVE-2020-7549"},"packages":[],"prev":{"headline":"Privilege escalation in EcoStruxureª and SmartStruxureª Power Monitoring and SCADA Software (see security notification for version information)","id":"CVE-2020-7547"},"products":["Smartlink, PowerTag, and Wiser Series Gateways (see security notification for version information)"],"published":"2020-12-01","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":"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":"2024-08-04","vendors":["n/a"]},"summary":"Insufficiently random values in Smartlink, PowerTag, and Wiser Gateways allow unauthorized users to bypass authentication and log in.","url":"https://insights.sbomify.com/CVE-2020-7548/"}
