CVE-2000-1022
The mailguard feature in Cisco Secure PIX Firewall 5.2(2) and earlier does not properly restrict access to SMTP commands, which allows remote attackers to execute restricted commands by sending a DATA command before sending the restricted commands.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (7.10%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
