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-2024-21872 in the wild and no public exploit code.\n\nAffected product: Electrolink Compact DAB 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-2024-21872/ (Markdown: https://insights.sbomify.com/CVE-2024-21872/index.md)","id":"CVE-2024-21872","markdown":"https://insights.sbomify.com/CVE-2024-21872/index.md","name":"CVE-2024-21872","record":{"aliases":["GHSA-9c86-qqfm-5hf3"],"analysis":{"component_type":"ics_ot","fix_type":"no_fix_stated","impacts":["privilege_escalation","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Broadcast transmitter","requires_auth":"none","summary":"Unauthenticated attackers can bypass authentication by manipulating cookies to access hidden pages and perform critical operations on Electrolink transmitters.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-565","name":"Reliance on Cookies without Validation and Integrity Checking"}],"description":"The device allows an unauthenticated attacker to bypass authentication \nand modify the cookie to reveal hidden pages that allows more critical \noperations to 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":"Electrolink FM/DAB/TV Transmitter Reliance on Cookies without Validation and Integrity Checking","id":"CVE-2024-21872","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2024"},"n_packages":0,"n_references":1,"next":{"headline":"DoS attack when broadcasting billboard messages","id":"CVE-2024-21875"},"packages":[],"prev":{"headline":"Privilege escalation in UEFI firmware for some Intel(R) Processors","id":"CVE-2024-21871"},"products":["Compact DAB Transmitter","Compact FM Transmitter","Digital FM Transmitter","High Power DAB Transmitter","Medium DAB Transmitter","Modular FM Transmitter","UHF TV Transmitter","VHF TV Transmitter"],"published":"2024-04-18","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2024-08-01","vendors":["Electrolink"]},"summary":"Unauthenticated attackers can bypass authentication by manipulating cookies to access hidden pages and perform critical operations on Electrolink transmitters.","url":"https://insights.sbomify.com/CVE-2024-21872/"}
