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-2025-13926 in the wild and no public exploit code.\n\nAffected product: Contemporary Controls BASControl20. 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-2025-13926/ (Markdown: https://insights.sbomify.com/CVE-2025-13926/index.md)","id":"CVE-2025-13926","markdown":"https://insights.sbomify.com/CVE-2025-13926/index.md","name":"CVE-2025-13926","record":{"aliases":["GHSA-5wpm-jgqp-3v9m"],"analysis":{"component_type":"ics_ot","fix_type":"no_fix_stated","impacts":["security_bypass","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Building Automation Controller","requires_auth":"none","summary":"Attackers can sniff network traffic to forge packets and make arbitrary requests to the BASC 20T controller, bypassing security controls.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-807","name":"Reliance on Untrusted Inputs in a Security Decision"}],"description":"An attacker could use data obtained by sniffing the network traffic to \nforge packets in order to make arbitrary requests to Contemporary \nControls BASC 20T.","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":"Contemporary Controls BASC 20T Reliance on Untrusted Inputs in a Security Decision","id":"CVE-2025-13926","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2025"},"n_packages":0,"n_references":3,"next":{"headline":"Allocation of Resources Without Limits or Throttling in GitLab","id":"CVE-2025-13927"},"packages":[],"prev":{"headline":"Multiple vulnerabilities in IBM Aspera Console","id":"CVE-2025-13925"},"products":["BASControl20"],"published":"2026-04-09","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":"total"},"state":"PUBLISHED","updated":"2026-04-10","vendors":["Contemporary Controls"]},"summary":"Attackers can sniff network traffic to forge packets and make arbitrary requests to the BASC 20T controller, bypassing security controls.","url":"https://insights.sbomify.com/CVE-2025-13926/"}
