Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-50707 in the wild and no public exploit code.\n\nAffected product: EFACEC BCU 500. 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-2023-50707/ (Markdown: https://insights.sbomify.com/CVE-2023-50707/index.md)","id":"CVE-2023-50707","markdown":"https://insights.sbomify.com/CVE-2023-50707/index.md","name":"CVE-2023-50707","record":{"aliases":["GHSA-29gw-r2hj-fm58"],"analysis":{"component_type":"ics_ot","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"EFACEC BCU 500","requires_auth":"low_privilege","summary":"An attacker can cause a denial-of-service condition on the EFACEC BCU 500 by sending custom requests during active user sessions.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"bcu_500_firmware","vendor":"efacec"}],"cvss":{"score":9.6,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"Through the exploitation of active user sessions, an attacker could send custom requests to cause a denial-of-service condition on the device.","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":"Uncontrolled Resource Consumption in EFACEC BCU 500","id":"CVE-2023-50707","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"yii2-authclient vulnerable to possible timing attack on string comparison in OAuth1, OAuth2 and OpenID Connect implementation","id":"CVE-2023-50708"},"packages":[],"prev":{"headline":"Improper Access Control in EFACEC UC 500E","id":"CVE-2023-50706"},"products":["BCU 500"],"published":"2023-12-19","related":[{"cvss_score":8.2,"headline":"Cross-Site Request Forgery in EFACEC BCU 500","id":"CVE-2023-6689","kev_date_added":null,"published":"2023-12-19"}],"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":"2024-08-02","vendors":["EFACEC"]},"summary":"An attacker can cause a denial-of-service condition on the EFACEC BCU 500 by sending custom requests during active user sessions.","url":"https://insights.sbomify.com/CVE-2023-50707/"}
