CVE-2020-12831

CVSS v3.1

5.3

Medium

VectorAV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N
Name of the Vulnerable Software and Affected Versions FRRouting FRR versions through 7.3.1
Description An issue was discovered in FRRouting FRR 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. 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.
Recommendations For versions through 7.3.1, consider changing the default permissions of the config file created by the init script to prevent world-readable access. As a temporary workaround, restrict access to the config file until a more permanent solution is applied.
