CVE-2020-3409 1 Cisco 35 Ie-3200-8p2s-e, Ie-3200-8t2s-e, Ie-3300-8p2s-a and 32 more 2022-10-27 6.1 MEDIUM 7.4 HIGH
A vulnerability in the PROFINET feature of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to cause an affected device to crash and reload, resulting in a denial of service (DoS) condition on the device. The vulnerability is due to insufficient processing logic for crafted PROFINET packets that are sent to an affected device. An attacker could exploit this vulnerability by sending crafted PROFINET packets to an affected device for processing. A successful exploit could allow the attacker to cause the device to crash and reload, resulting in a DoS condition on the device.

CVE-2011-3279 1 Cisco 2 Ios, Ios Xe 2022-06-02 7.8 HIGH N/A
The provider-edge MPLS NAT implementation in Cisco IOS 12.1 through 12.4 and 15.0 through 15.1, and IOS XE 3.1.xSG, allows remote attackers to cause a denial of service (device reload) via a malformed SIP packet to UDP port 5060, aka Bug ID CSCti98219.
CVE-2011-0946 1 Cisco 2 Ios, Ios Xe 2022-06-02 7.8 HIGH N/A
The NAT implementation in Cisco IOS 12.1 through 12.4 and 15.0 through 15.1, and IOS XE 3.1.xSG, allows remote attackers to cause a denial of service (device reload or hang) via malformed NetMeeting Directory (aka Internet Locator Service or ILS) LDAP traffic, aka Bug ID CSCtd10712.
CVE-2009-2862 1 Cisco 1 Ios 2022-06-02 4.3 MEDIUM N/A
The Object Groups for Access Control Lists (ACLs) feature in Cisco IOS 12.2XNB, 12.2XNC, 12.2XND, 12.4MD, 12.4T, 12.4XZ, and 12.4YA allows remote attackers to bypass intended access restrictions via crafted requests, aka Bug IDs CSCsx07114, CSCsu70214, CSCsw47076, CSCsv48603, CSCsy54122, and CSCsu50252.
CVE-2008-3813 1 Cisco 1 Ios 2022-06-02 7.8 HIGH N/A
Unspecified vulnerability in Cisco IOS 12.2 and 12.4, when the L2TP mgmt daemon process is enabled, allows remote attackers to cause a denial of service (device reload) via a crafted L2TP packet.
CVE-2008-3812 1 Cisco 1 Ios 2022-06-02 7.1 HIGH N/A
