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-2023-42769 in the wild and no public exploit code.\n\nAffected product: Sielco Analog FM transmitter. 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-2023-42769/ (Markdown: https://insights.sbomify.com/CVE-2023-42769/index.md)","id":"CVE-2023-42769","markdown":"https://insights.sbomify.com/CVE-2023-42769/index.md","name":"CVE-2023-42769","record":{"aliases":["GHSA-f78q-jqxf-66cm"],"analysis":{"component_type":"ics_ot","fix_type":"no_fix_stated","impacts":["privilege_escalation","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"FM transmitter","requires_auth":"none","summary":"Remote attackers can brute force short session IDs to bypass authentication and manipulate Sielco FM transmitters and radio links.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"analog_fm_transmitter_exc1000gt_firmware","vendor":"sielco"},{"product":"analog_fm_transmitter_exc1000gx_firmware","vendor":"sielco"},{"product":"analog_fm_transmitter_exc100gt_firmware","vendor":"sielco"},{"product":"analog_fm_transmitter_exc120gt_firmware","vendor":"sielco"},{"product":"analog_fm_transmitter_exc120gx_firmware","vendor":"sielco"},{"product":"analog_fm_transmitter_exc1600gx_firmware","vendor":"sielco"},{"product":"analog_fm_transmitter_exc2000gx_firmware","vendor":"sielco"},{"product":"analog_fm_transmitter_exc3000gx_firmware","vendor":"sielco"},{"product":"analog_fm_transmitter_exc300gt_firmware","vendor":"sielco"},{"product":"analog_fm_transmitter_exc300gx_firmware","vendor":"sielco"},{"product":"analog_fm_transmitter_exc30gt_firmware","vendor":"sielco"},{"product":"analog_fm_transmitter_exc5000gt_firmware","vendor":"sielco"},{"product":"analog_fm_transmitter_exc5000gx_firmware","vendor":"sielco"},{"product":"radio_link_exc19_firmware","vendor":"sielco"},{"product":"radio_link_rtx19_firmware","vendor":"sielco"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","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-307","name":"Improper Restriction of Excessive Authentication Attempts"},{"id":"CWE-284","name":"Improper Access Control"}],"description":"The cookie session ID is of insufficient length and can be exploited by \nbrute force, which may allow a remote attacker to obtain a valid \nsession, bypass authentication, and manipulate the transmitter.","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":"Sielco Radio Link and Analog FM Transmitters Improper Access Control","id":"CVE-2023-42769","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2023"},"n_packages":0,"n_references":2,"next":{"headline":"Red Lion Controls Sixnet RTU Authentication Bypass Using An Alternative Path Or Channel","id":"CVE-2023-42770"},"packages":[],"prev":{"headline":"BIG-IP iControl REST vulnerability","id":"CVE-2023-42768"},"products":["Analog FM transmitter","Radio Link"],"published":"2023-10-26","related":[{"cvss_score":8.8,"headline":"Sielco Radio Link and Analog FM Transmitters Cross-Site Request Forgery","id":"CVE-2023-45317","kev_date_added":null,"published":"2023-10-26"},{"cvss_score":6.5,"headline":"Sielco Radio Link and Analog FM Transmitters Privilege Defined With Unsafe Actions","id":"CVE-2023-41966","kev_date_added":null,"published":"2023-10-26"},{"cvss_score":6.5,"headline":"Sielco Radio Link and Analog FM Transmitters Improper Access Control","id":"CVE-2023-45228","kev_date_added":null,"published":"2023-10-26"}],"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":"total"},"state":"PUBLISHED","updated":"2025-01-16","vendors":["Sielco","Sielco "]},"summary":"Remote attackers can brute force short session IDs to bypass authentication and manipulate Sielco FM transmitters and radio links.","url":"https://insights.sbomify.com/CVE-2023-42769/"}
