Vulnerability from csaf_certbund - Published: 2024-09-25 22:00 - Updated: 2024-09-25 22:00Es besteht eine Schwachstelle in Cisco IOS auf Cisco Industrial Ethernet Switches. Dieser Fehler existiert in der ACL-Programmierung (Access Control List) aufgrund der falschen Handhabung von IPv4-ACLs auf geswitchten virtuellen Schnittstellen, wenn das Resilient Ethernet Protocol (REP) aktiviert ist. Ein entfernter, anonymer Angreifer kann diese Schwachstelle ausnutzen, um eine konfigurierte ACL zu umgehen.
