Summary
A "logic error" in Cisco IOS 12.0 through 12.4, when a Multiprotocol Label Switching (MPLS) VPN with extended communities is configured, sometimes causes a corrupted route target (RT) to be used, which allows remote attackers to read traffic from other VPNs in opportunistic circumstances.
Exploit prediction
2.65% chance of exploitation in the next 30 days, higher than 85% of all scored CVEs (FIRST EPSS, 2026-11-08).
