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-2026-35090 in the wild and no public exploit code.\n\nAffected product: Slican CCT-1668. 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-2026-35090/ (Markdown: https://insights.sbomify.com/CVE-2026-35090/index.md)","id":"CVE-2026-35090","markdown":"https://insights.sbomify.com/CVE-2026-35090/index.md","name":"CVE-2026-35090","record":{"aliases":["GHSA-4fcp-hv44-rggc"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["privilege_escalation","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"telephone exchange","requires_auth":"none","summary":"Unauthenticated attackers can bypass admin authentication via caller ID to gain full control of Slican telephone exchanges.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERT-PL","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-288","name":"Authentication Bypass Using an Alternate Path or Channel"}],"description":"In Slican telephone exchanges it is possible to manage the control panel remotely. An unauthenticated attacker can connect to the modem via a telephone with a specific caller ID. This allows them to bypass admin authentication and gain full access to the service protocol and configuration panel. This vulnerability is independent of the telephone exchanges configuration. If remote access is disabled, calling with this caller ID will temporarily enable it.\n\nThis issue was fixed in versions below:\n- IPL-256: version 6.61.0040\n- IPM-032: version 6.61.0040\n- CCT-1668: version 6.56.0430\n- MAC-6400: version 6.56.0430\n- CXS-0424: version 6.30.0510\n\nThe issue STILL EXISTS in End-Of-Life telephone exchanges in versions 4.xx and below:\n- CCT-1668 (CCT1CPU)\n- MAC-6400\n- CXS-0424\nThese products were discontinued in 2011 and 2012 and and will not receive updates.
