{“lastseen”:””,”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.\u00a0This allows them to bypass admin authentication and\u00a0gain full access to the service protocol and configuration panel. This vulnerability is independent of the telephone exchanges configuration.\u00a0If 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. These products require a hardware update in order to receive a software update. The vendor recommends that users of these devices contact the their service department directly to determine the options for upgrading.”,”published”:”2026-05-27T12:42:47.318Z”,”modified”:”2026-05-27T12:42:47.318Z”,”type”:”cve”,”title”:”Authentication Bypass in Slican telephone exchanges”,”source”:”CERT-PL”,”references”:”https:\/\/cert.pl\/posts\/2026\/05\/CVE-2026-35087″,”id”:”CVE-2026-35090″,”bulletinFamily”:””,”cwe”:[“CWE-288″],”cvelist”:null,”sourceData”:”Slican CCT-1668 0\\nSlican MAC-6400 0\\nSlican CXS-0424 0\\nSlican IPL-256 0\\nSlican IPM-032 0″,”sourceHref”:””,”cvss”:{“score”:9.3,”severity”:”CRITICAL”,”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″},”cvss2″:{},”cvss3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””,”cvssV3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””}},”href”:””,”category_name”:”CVE”,”post_link”:””,”product”:”CCT-1668″,”version”:”0″,”vendor”:”Slican”,”ai_description”:”Unauthenticated attacker can bypass admin authentication and gain full access to the service protocol and configuration panel via a specific caller ID”,”ai_severity”:”Critical”,”ai_vendor”:”Slican”,”ai_product”:”Slican telephone exchanges”,”ai_version”:”4.xx and below, 6.61.0040, 6.56.0430, 6.30.0510″,”ai_score”:9.3}<\/p>\n","protected":false},"excerpt":{"rendered":"
