An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-22766 and fix it if it is affected.\n\nWhat it is: CVE-2021-22766 is a high-severity denial of service vulnerability in PowerLogic EGX100 (Versions 3.0.0 and newer) and PowerLogic EGX300 (All Versions), published on 11 Jun 2021. 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-2021-22766 in the wild and no public exploit code.\n\nAffected product: PowerLogic EGX100 (Versions 3.0.0 and newer) and PowerLogic EGX300 (All Versions). 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-2021-22766/ (Markdown: https://insights.sbomify.com/CVE-2021-22766/index.md)","id":"CVE-2021-22766","markdown":"https://insights.sbomify.com/CVE-2021-22766/index.md","name":"CVE-2021-22766","record":{"aliases":["GHSA-473q-p3cq-866g"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"PowerLogic energy gateway","requires_auth":"none","summary":"A specially crafted HTTP packet can cause a denial of service in Schneider Electric PowerLogic EGX100 and EGX300 energy gateways.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"schneider","cpe":[{"product":"powerlogic_egx100_firmware","vendor":"schneider-electric"},{"product":"powerlogic_egx300_firmware","vendor":"schneider-electric"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"A CWE-20: Improper Input Validation vulnerability exists in PowerLogic EGX100 (Versions 3.0.0 and newer) and PowerLogic EGX300 (All Versions) that could cause denial of service via a specially crafted HTTP packet","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":"Denial of service in PowerLogic EGX100 (Versions 3.0.0 and newer) and PowerLogic EGX300 (All Versions)","id":"CVE-2021-22766","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Other in PowerLogic EGX100 (Versions 3.0.0 and newer) and PowerLogic EGX300 (All Versions)","id":"CVE-2021-22767"},"packages":[],"prev":{"headline":"Other in PowerLogic EGX100 (Versions 3.0.0 and newer) and PowerLogic EGX300 (All Versions)","id":"CVE-2021-22765"},"products":["PowerLogic EGX100 (Versions 3.0.0 and newer) and PowerLogic EGX300 (All Versions)"],"published":"2021-06-11","related":[{"cvss_score":9.8,"headline":"Other in PowerLogic EGX100 (Versions 3.0.0 and newer) and PowerLogic EGX300 (All Versions)","id":"CVE-2021-22765","kev_date_added":null,"published":"2021-06-11"},{"cvss_score":9.8,"headline":"Other in PowerLogic EGX100 (Versions 3.0.0 and newer) and PowerLogic EGX300 (All Versions)","id":"CVE-2021-22767","kev_date_added":null,"published":"2021-06-11"},{"cvss_score":9.8,"headline":"Other in PowerLogic EGX100 (Versions 3.0.0 and newer) and PowerLogic EGX300 (All Versions)","id":"CVE-2021-22768","kev_date_added":null,"published":"2021-06-11"}],"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-05-29","vendors":["n/a"]},"summary":"A specially crafted HTTP packet can cause a denial of service in Schneider Electric PowerLogic EGX100 and EGX300 energy gateways.","url":"https://insights.sbomify.com/CVE-2021-22766/"}
