Component: Not specified by the source

Attack conditions (Vendor/CNA, CVSS 4.0): Network (remote) · High privileges required · No user interaction required

What an attacker can do

A user with the administrator tag can write a .log-suffixed file to an arbitrary filesystem path writable by the rabbitmq user via the tracing plugin's name parameter, e.g. /etc/cron.d/x.log (if writable) or overwrite existing .log files outside the trace directory. Vendor/CNA’s CVSS 4.0 assessment (base score 2.1/10) rates confidentiality and availability impact as none; integrity impact as low.
