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-2021-22749 in the wild and no public exploit code.\n\nAffected product: Modicon X80 BMXNOR0200H RTU SV1.70 IR22 and prior. 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-2021-22749/ (Markdown: https://insights.sbomify.com/CVE-2021-22749/index.md)","id":"CVE-2021-22749","markdown":"https://insights.sbomify.com/CVE-2021-22749/index.md","name":"CVE-2021-22749","record":{"aliases":["GHSA-xmrj-wjpx-qx78"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Modicon RTU","requires_auth":"none","summary":"An attacker can send a crafted HTTP request to the Modicon X80 RTU web server to leak sensitive configuration and telemetry parameters.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"schneider","cpe":[{"product":"modicon_x80_bmxnor0200h_rtu_firmware","vendor":"schneider-electric"}],"cvss":{"score":5.3,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"A CWE-200: Exposure of Sensitive Information to an Unauthorized Actor vulnerability exists in Modicon X80 BMXNOR0200H RTU SV1.70 IR22 and prior that could cause information leak concerning the current RTU configuration including communication parameters dedicated to telemetry, when a specially crafted HTTP request is sent to the web server of the module.","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":"Information disclosure in Modicon X80 BMXNOR0200H RTU SV1.70 IR22 and prior","id":"CVE-2021-22749","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in IGSS Definition (Def.exe) V15.0.0.21041 and prior","id":"CVE-2021-22750"},"packages":[],"prev":{"headline":"Path traversal in C-Bus Toolkit (V1.15.9 and prior), C-Gate Server (V2.11.7 and prior)","id":"CVE-2021-22748"},"products":["Modicon X80 BMXNOR0200H RTU SV1.70 IR22 and prior"],"published":"2021-06-11","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":"An attacker can send a crafted HTTP request to the Modicon X80 RTU web server to leak sensitive configuration and telemetry parameters.","url":"https://insights.sbomify.com/CVE-2021-22749/"}
