CVE-2026-35090 (GCVE-0-2026-35090)
Vulnerability from nvd – Published: 2026-05-27 12:42 – Updated: 2026-05-27 15:29

Title
Authentication Bypass in Slican telephone exchanges
Summary
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.
This issue was fixed in versions below:
- IPL-256: version 6.61.0040
- IPM-032: version 6.61.0040
- CCT-1668: version 6.56.0430
- MAC-6400: version 6.56.0430
- CXS-0424: version 6.30.0510
The issue STILL EXISTS in End-Of-Life telephone exchanges in versions 4.xx and below:
- CCT-1668 (CCT1CPU)
- MAC-6400
- CXS-0424
These 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.

Title
Authentication Bypass in Slican telephone exchanges
Summary
Slican telephone exchanges allow administrative protocol authentication bypass. An attacker can bypass the need to enter login credentials by executing the appropriate command.
This issue was fixed in versions below:
- NCP: version 1.24.0250
- IPx series: version 6.61.0040
- CCT-1668: version 6.56.0430
- MAC-6400: version 6.56.0430
- CXS-0424: version 6.30.0510
The issue STILL EXISTS in End-Of-Life telephone exchanges in versions 4.xx and below:
- CCT-1668 (CCT1CPU)
- MAC-6400
- CXS-0424
These 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.

Title
Authentication Bypass in Slican telephone exchanges
Summary
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.
This issue was fixed in versions below:
- IPL-256: version 6.61.0040
- IPM-032: version 6.61.0040
- CCT-1668: version 6.56.0430
- MAC-6400: version 6.56.0430
- CXS-0424: version 6.30.0510
The issue STILL EXISTS in End-Of-Life telephone exchanges in versions 4.xx and below:
- CCT-1668 (CCT1CPU)
- MAC-6400
- CXS-0424
These 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.

Summary
In Slican telephone exchanges secure key is generated in a predictable manner using properties of the telephone exchange which can be obtained without authentication. An unauthenticated attacker can deduce the secure key and obtain admin credentials.
This issue was fixed in versions below:
- IPx series: version 6.61.0040
- CCT-1668: version 6.56.0430
- MAC-6400: version 6.56.0430
- CXS-0424: version 6.30.0510
The issue STILL EXISTS in End-Of-Life telephone exchanges in versions 4.xx and below:
- CCT-1668 (CCT1CPU)
- MAC-6400
- CXS-0424
These 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.

Title
Authentication Bypass in Slican telephone exchanges
Summary
Slican telephone exchanges allow administrative protocol authentication bypass. An attacker can bypass the need to enter login credentials by executing the appropriate command.
This issue was fixed in versions below:
- NCP: version 1.24.0250
- IPx series: version 6.61.0040
- CCT-1668: version 6.56.0430
- MAC-6400: version 6.56.0430
- CXS-0424: version 6.30.0510
The issue STILL EXISTS in End-Of-Life telephone exchanges in versions 4.xx and below:
- CCT-1668 (CCT1CPU)
- MAC-6400
- CXS-0424
These 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.
