The ACL implementation in Cisco IOS before 15.1(1)SY on Catalyst 6500 and 7600 devices allows local users to cause a denial of service (device reload) via a "no object-group" command followed by an object-group command, aka Bug ID CSCts16133.

Security readout for executives and security teams

This issue could let a local user with access to Cisco IOS configuration functions trigger a reload on Catalyst 6500 or 7600 devices. For executives, the concern is availability: affected core network equipment may briefly go offline if misused by someone with local privileges. Exposure appears limited to Cisco Catalyst 6500 and 7600 devices running Cisco IOS versions before 15.1(1)SY, where users can make relevant ACL/object-group configuration changes. Treat as a targeted network availability risk. Prioritize if these platforms still support critical switching or routing paths, especially where many administrators or automation systems can change ACL configuration. Mitigation focus: Inventory Catalyst 6500 and 7600 devices and record IOS versions.; Review Cisco 15.1(1)SY release notes and CSCts16133 guidance.; Plan upgrade or vendor-recommended remediation for affected devices..
