CVE-2020-13768
In MiniShare before 1.4.2, there is a stack-based buffer overflow via an HTTP PUT request, which allows an attacker to achieve arbitrary code execution, a similar issue to CVE-2018-19861, CVE-2018-19862, and CVE-2019-17601.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.09%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
