CVE-2018-19646
The Python CGI scripts in PWS in Imperva SecureSphere 13.0.10, 13.1.10, and 13.2.10 allow remote attackers to execute arbitrary OS commands because command-line arguments are mishandled.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.45%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
