CVE-2020-3425 1 Cisco 110 4221 Integrated Services Router, 4321 Integrated Services Router, 4331 Integrated Services Router and 107 more 2021-10-07 6.5 MEDIUM 8.8 HIGH
Multiple vulnerabilities in the web management framework of Cisco IOS XE Software could allow an authenticated, remote attacker with read-only privileges to elevate privileges to the level of an Administrator user on an affected device. For more information about these vulnerabilities, see the Details section of this advisory.
CVE-2020-3479 1 Cisco 27 1100 Integrated Services Router, 4221 Integrated Services Router, 4321 Integrated Services Router and 24 more 2021-10-07 7.8 HIGH 7.5 HIGH
A vulnerability in the implementation of Multiprotocol Border Gateway Protocol (MP-BGP) for the Layer 2 VPN (L2VPN) Ethernet VPN (EVPN) address family in Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition. The vulnerability is due to incorrect processing of Border Gateway Protocol (BGP) update messages that contain crafted EVPN attributes. An attacker could exploit this vulnerability by sending BGP update messages with specific, malformed attributes to an affected device. A successful exploit could allow the attacker to cause an affected device to crash, resulting in a DoS condition.
CVE-2019-12654 1 Cisco 17 1100 Integrated Services Router, 4221 Integrated Services Router, 4321 Integrated Services Router and 14 more 2019-10-09 7.8 HIGH 7.5 HIGH
A vulnerability in the common Session Initiation Protocol (SIP) library of Cisco IOS and IOS XE Software could allow an unauthenticated, remote attacker to trigger a reload of an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to insufficient sanity checks on an internal data structure. An attacker could exploit this vulnerability by sending a sequence of malicious SIP messages to an affected device. An exploit could allow the attacker to cause a NULL pointer dereference, resulting in a crash of the iosd process. This triggers a reload of the device.
