Successful exploitation of these remotely exploitable vulnerabilities could allow an unauthenticated attacker to gain full access to the system, disclose sensitive information, or access hidden resources. CISA discovered a public proof of concept (PoC) as authored by Gjoko Krstic.
The following versions EuroTel ETL3100 radio transmitter suffer from the vulnerabilities:
- ETL3100: version v01c01
- ETL3100: version v01x37
In one issue, EuroTel ETL3100 versions v01c01 and v01x37 does not limit the number of attempts to guess administrative credentials in remote password attacks to gain full control of the system.
CVE-2023-6928 is the case number for this vulnerability, which has a CVSS v3.1 base score of 9.8.
In addition, EuroTel ETL3100 versions v01c01 and v01x37 are vulnerable to insecure direct object references that occur when the application provides direct access to objects based on user-supplied input. As a result of this vulnerability, attackers can bypass authorization, access the hidden resources on the system, and execute privileged functionalities.
CVE-2023-6929 is the case number assigned to this vulnerability, which has a CVSS v3.1 base score of 7.5.
Also, EuroTel ETL3100 versions v01c01 and v01x37 suffer from an unauthenticated configuration and log download vulnerability. This enables the attacker to disclose sensitive information and assist in authentication bypass, privilege escalation, and full system access.
CVE-2023-6930 is the case number for this vulnerability, which has a CVSS v3.1 base score of 9.4.
The product sees use mainly in the communications sector, and on a global basis.
An attacker could leverage these low complexity vulnerabilities.
Italy-based EuroTel has not responded to requests to work with CISA to mitigate these vulnerabilities. Users of affected versions of ETL3100 should contact EuroTel customer support for additional information.
