CVE-2021-1529 1 Cisco 57 1000 Integrated Services Router, 1100-4g\/6g Integrated Services Router, 1100-4p Integrated Services Router and 54 more 2024-02-28 6.9 MEDIUM 7.8 HIGH
A vulnerability in the CLI of Cisco IOS XE SD-WAN Software could allow an authenticated, local attacker to execute arbitrary commands with root privileges. The vulnerability is due to insufficient input validation by the system CLI. An attacker could exploit this vulnerability by authenticating to an affected device and submitting crafted input to the system CLI. A successful exploit could allow the attacker to execute commands on the underlying operating system with root privileges.
CVE-2021-34727 1 Cisco 49 1000 Integrated Services Router, 1100-4g\/6g Integrated Services Router, 1100-4p Integrated Services Router and 46 more 2024-02-28 10.0 HIGH 9.8 CRITICAL
A vulnerability in the vDaemon process in Cisco IOS XE SD-WAN Software could allow an unauthenticated, remote attacker to cause a buffer overflow on an affected device. This vulnerability is due to insufficient bounds checking when an affected device processes traffic. An attacker could exploit this vulnerability by sending crafted traffic to the device. A successful exploit could allow the attacker to cause a buffer overflow and possibly execute arbitrary commands with root-level privileges, or cause the device to reload, which could result in a denial of service condition.
CVE-2021-1621 1 Cisco 45 1000 Integrated Services Router, 1100-4g\/6g Integrated Services Router, 1100-4p Integrated Services Router and 42 more 2024-02-28 3.3 LOW 7.4 HIGH
A vulnerability in the Layer 2 punt code of Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to cause a queue wedge on an interface that receives specific Layer 2 frames, resulting in a denial of service (DoS) condition. This vulnerability is due to improper handling of certain Layer 2 frames. An attacker could exploit this vulnerability by sending specific Layer 2 frames on the segment the router is connected to. A successful exploit could allow the attacker to cause a queue wedge on the interface, resulting in a DoS condition.
CVE-2019-12654 1 Cisco 17 1000 Integrated Services Router, 1100 Integrated Services Router, 4000 Integrated Services Router and 14 more 2024-02-28 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.
