CVE-2020-7040
storeBackup.pl in storeBackup through 3.5 relies on the /tmp/storeBackup.lock pathname, which allows symlink attacks that possibly lead to privilege escalation.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.87%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
storeBackup.pl in storeBackup through 3.5 relies on the /tmp/storeBackup.lock pathname, which allows symlink attacks that possibly lead to privilege escalation. (Local users can also create a plain file named /tmp/storeBackup.lock to block use of storeBackup until an admin manually deletes that file.)
