CVE-2020-15397 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. 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).. EPSS estimates a 0.54% chance of exploitation in the next 30 days.
