Privilege Escalation via Unprivileged User-Writable Directories in HylaFAX

CVE-2020-15397 · HIGH Severity

CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

HylaFAX+ through 7.0.2 and HylaFAX Enterprise have scripts that execute binaries from directories writable by unprivileged users (e.g., locations under /var/spool/hylafax that are writable by the uucp account). This allows these users to execute code in the context of the user calling these binaries (often root).
