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-2024-5539 in the wild and no public exploit code.\n\nAffected product: Automated Logic WebCTRL. 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-2024-5539/ (Markdown: https://insights.sbomify.com/CVE-2024-5539/index.md)","id":"CVE-2024-5539","markdown":"https://insights.sbomify.com/CVE-2024-5539/index.md","name":"CVE-2024-5539","record":{"aliases":["GHSA-2m76-j3f4-m2c2"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["security_bypass","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Building automation server","requires_auth":"none","summary":"Attackers can bypass access restrictions on ALC WebCTRL and Carrier i-Vu building automation servers to expose sensitive information.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Carrier","cpe":[],"cvss":{"score":9.2,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:H/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"The Access Control Bypass vulnerability found in ALC WebCTRL and Carrier i-Vu in versions up to and including 8.5 allows a malicious actor to bypass intended access restrictions and expose sensitive information via the \n\nweb based building automation server.","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":"ALC WebCTRL Carrier i-Vu Access Control Bypass","id":"CVE-2024-5539","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":"ALC WebCTRL Carrier i-Vu Reflected Cross-Site Scripting","id":"CVE-2024-5540"},"packages":[],"prev":{"headline":"This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.","id":"CVE-2024-5538"},"products":["WebCTRL","i-Vu"],"published":"2025-11-27","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":"2025-11-28","vendors":["Automated Logic","Carrier"]},"summary":"Attackers can bypass access restrictions on ALC WebCTRL and Carrier i-Vu building automation servers to expose sensitive information.","url":"https://insights.sbomify.com/CVE-2024-5539/"}
