CVE-1999-1466
Vulnerability in Cisco routers versions 8.2 through 9.1 allows remote attackers to bypass access control lists when extended IP access lists are used on certain interfaces, the IP route cache is enabled, and the access list uses the "established" keyword.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.32%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
