Any signed-in user can exploit it over the network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-33533 and fix it if it is affected.\n\nWhat it is: CVE-2021-33533 is a high-severity command injection vulnerability in Weidmüller IE-WL(T)-BL-AP-CL-XX, published on 25 Jun 2021. Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-33533 in the wild and no public exploit code.\n\nAffected product: Weidmüller IE-WL(T)-BL-AP-CL-XX. 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-2021-33533/ (Markdown: https://insights.sbomify.com/CVE-2021-33533/index.md)","id":"CVE-2021-33533","markdown":"https://insights.sbomify.com/CVE-2021-33533/index.md","name":"CVE-2021-33533","record":{"aliases":["GHSA-6g5w-7qx6-q4pr"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Industrial WLAN device","requires_auth":"low_privilege","summary":"Authenticated low-privilege users can execute arbitrary commands on Weidmüller Industrial WLAN devices via the iw_serverip parameter.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERTVDE","cpe":[{"product":"ie-wl-bl-ap-cl-eu_firmware","vendor":"weidmueller"},{"product":"ie-wl-bl-ap-cl-us_firmware","vendor":"weidmueller"},{"product":"ie-wl-vl-ap-br-cl-eu_firmware","vendor":"weidmueller"},{"product":"ie-wl-vl-ap-br-cl-us_firmware","vendor":"weidmueller"},{"product":"ie-wlt-bl-ap-cl-eu_firmware","vendor":"weidmueller"},{"product":"ie-wlt-bl-ap-cl-us_firmware","vendor":"weidmueller"},{"product":"ie-wlt-vl-ap-br-cl-eu_firmware","vendor":"weidmueller"},{"product":"ie-wlt-vl-ap-br-cl-us_firmware","vendor":"weidmueller"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"In Weidmueller Industrial WLAN devices in multiple versions an exploitable command injection vulnerability exists in the iw_webs functionality.
