| Vulnerability Name: | CVE-2020-12831 |
| Assigned: | 2020-05-03 |
| Published: | 2020-05-03 |
| Updated: | 2021-07-21 |
| Summary: | ** DISPUTED ** An issue was discovered in FRRouting FRR (aka Free Range Routing) through 7.3.1. When using the split-config feature, the init script creates an empty config file with world-readable default permissions, leading to a possible information leak via tools/frr.in and tools/frrcommon.sh.in.
Note: some parties consider this user error, not a vulnerability, because the permissions are under the control of the user before any sensitive information is present in the file. |
