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-2021-22772 in the wild and no public exploit code.\n\nAffected product: Easergy T200 ((Modbus) SC2-04MOD-07000100 and earlier), Easergy T200 ((IEC104) SC2-04IEC-07000100 and earlier), and Easergy T200 ((DNP3) SC2-04DNP-07000102 and earlier). 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-2021-22772/ (Markdown: https://insights.sbomify.com/CVE-2021-22772/index.md)","id":"CVE-2021-22772","markdown":"https://insights.sbomify.com/CVE-2021-22772/index.md","name":"CVE-2021-22772","record":{"aliases":["GHSA-9gg2-wj6f-29qm"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Easergy T200 RTU","requires_auth":"none","summary":"Attackers can bypass authentication to perform unauthorized operations on Schneider Electric Easergy T200 devices.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"schneider","cpe":[{"product":"t200e_firmware","vendor":"schneider-electric"},{"product":"t200i_firmware","vendor":"schneider-electric"},{"product":"t200p_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-306","name":"Missing Authentication for Critical Functionality"}],"description":"A CWE-306: Missing Authentication for Critical Function vulnerability exists in Easergy T200 ((Modbus) SC2-04MOD-07000100 and earlier), Easergy T200 ((IEC104) SC2-04IEC-07000100 and earlier), and Easergy T200 ((DNP3) SC2-04DNP-07000102 and earlier) that could cause unauthorized operation when authentication is bypassed.","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":"Missing authorization in Easergy T200 ((Modbus) SC2-04MOD-07000100 and earlier), Easergy T200 ((IEC104) SC2-04IEC-07000100 and earlier), and Easergy T200 ((DNP3) SC2-04DNP-07000102 and earlier)","id":"CVE-2021-22772","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Auth bypass in EVlink City (EVC1S22P4 / EVC1S7P4 all versions prior to R8 V3.4.0.1), EVlink Parking (EVW2 / EVF2 / EV.2 all versions prior to R8 V3.4.0.1), and EVlink Smart Wallbox (EVB1A all versions prior to R8 V3.4.0.1 )","id":"CVE-2021-22773"},"packages":[],"prev":{"headline":"Code injection in Easergy T300 with firmware V2.7.1 and older","id":"CVE-2021-22771"},"products":["Easergy T200 ((Modbus) SC2-04MOD-07000100 and earlier), Easergy T200 ((IEC104) SC2-04IEC-07000100 and earlier), and Easergy T200 ((DNP3) SC2-04DNP-07000102 and earlier)"],"published":"2021-07-21","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":"2024-08-03","vendors":["n/a"]},"summary":"Attackers can bypass authentication to perform unauthorized operations on Schneider Electric Easergy T200 devices.","url":"https://insights.sbomify.com/CVE-2021-22772/"}
