CVE-2019-10143 (CCN-161571)

Assigned:2019-05-01
Published:2019-05-01
Updated:2023-02-12
Summary:** DISPUTED ** It was discovered freeradius up to and including version 3.0.19 does not correctly configure logrotate, allowing a local attacker who already has control of the radiusd user to escalate his privileges to root, by tricking logrotate into writing a radiusd-writable file to a directory normally inaccessible by the radiusd user.
Note: the upstream software maintainer has stated "there is simply no way for anyone to gain privileges through this alleged issue."
