CVE-2017-10932: All: Insecure deserialization
CVE-2017-10932 is rated critical with a CVSS v3.1 base score of 9.8 and NVD lists 6 affected products, including ZTE Nr8120 Firmware. Per its scoring, it can be exploited over the network, without authentication, without any user interaction. The scored impact on confidentiality, integrity and availability is the highest available.
Vulnerability description
All versions prior to V12.17.20 of the ZTE Microwave NR8000 series products - NR8120, NR8120A, NR8120, NR8150, NR8250, NR8000 TR and NR8950 are the applications of C/S architecture using the Java RMI service in which the servers use the Apache Commons Collections (ACC) library that may result in Java deserialization vulnerabilities. An unauthenticated remote attacker can exploit the vulnerabilities by sending a crafted RMI request to execute arbitrary code on the target host.
