CVE-2021-32570 : What You Need to Know

This CVE-2021-32570 affects Ericsson Network Manager (ENM) releases before version 21.2. It allows users in the same AMOS authorization group to retrieve data from specific log files, potentially leading to privilege escalation.

Understanding CVE-2021-32570

This CVE impacts the security of ENM systems by enabling unauthorized access to sensitive log files, posing a risk of privilege escalation within the network.

What is CVE-2021-32570?

In ENM releases prior to 21.2, all users belonging to the AMOS authorization group can access certain log files, considered highly privileged data in the system. Unauthorized users can read information stored within these logs, potentially leading to unauthorized escalation of their privileges.

The Impact of CVE-2021-32570

The vulnerability allows unauthorized users to retrieve and access sensitive log file data, which can be exploited for conducting privilege escalation attacks within the ENM system. This poses a significant security risk as it compromises the integrity and confidentiality of the network.
