CVE-2022-28391
BusyBox through 1.35.0 allows remote attackers to execute arbitrary code if netstat is used to print a DNS PTR record's value to a VT compatible terminal.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.52%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
BusyBox through 1.35.0 allows remote attackers to execute arbitrary code if netstat is used to print a DNS PTR record's value to a VT compatible terminal. Alternatively, the attacker could choose to change the terminal's colors.
