VAR-201511-0217
Vulnerability from variot - Updated: 2025-04-13 23:29Cisco IOS 15.2(04)M6 and 15.4(03)S lets physical-interface ACLs supersede tunnel-interface ACLs, which allows remote attackers to bypass intended network-traffic restrictions in opportunistic circumstances by using a tunnel, aka Bug ID CSCur01042. Cisco IOS The tunnel interface ACL The physical interface ACL As an alternative, there is a vulnerability that bypasses network traffic restrictions. Vendors have confirmed this vulnerability Bug ID CSCur01042 It is released as. Supplementary information : CWE Vulnerability type by CWE-284: Improper Access Control ( Inappropriate access control ) Has been identified. http://cwe.mitre.org/data/definitions/284.htmlUsing a tunnel by a third party can circumvent network traffic restrictions. Cisco IOS is a popular Internet operating system. A security vulnerability exists in Cisco IOS. Remote attackers can exploit this issue to bypass security restrictions and perform unauthorized actions. This may aid in further attacks
