CVSS: 8.8EPSS: 0%CPEs: 288EXPL: 0CVE-2022-20824 – Cisco FXOS and NX-OS Software Cisco Discovery Protocol Denial of Service and Arbitrary Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2022-20824
A vulnerability in the Cisco Discovery Protocol feature of Cisco FXOS Software and Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to execute arbitrary code with root privileges or cause a denial of service (DoS) condition on an affected device. This vulnerability is due to improper input validation of specific values that are within a Cisco Discovery Protocol message. An attacker could exploit this vulnerability by sending a malicious Cisco Discovery Protocol packet to an affected device. A successful exploit could allow the attacker to execute arbitrary code with root privileges or cause the Cisco Discovery Protocol process to crash and restart multiple times, which would cause the affected device to reload, resulting in a DoS condition. Note: Cisco Discovery Protocol is a Layer 2 protocol. • https://security.netapp.com/advisory/ntap-20220923-0001 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-nxos-cdp-dos-ce-wWvPucC9 • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •
CVSS: 8.6EPSS: 0%CPEs: 294EXPL: 0CVE-2022-20823 – Cisco NX-OS Software OSPFv3 Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2022-20823
A vulnerability in the OSPF version 3 (OSPFv3) feature of Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to incomplete input validation of specific OSPFv3 packets. An attacker could exploit this vulnerability by sending a malicious OSPFv3 link-state advertisement (LSA) to an affected device. A successful exploit could allow the attacker to cause the OSPFv3 process to crash and restart multiple times, causing the affected device to reload and resulting in a DoS condition. Note: The OSPFv3 feature is disabled by default. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-nxos-ospfv3-dos-48qutcu • CWE-125: Out-of-bounds Read CWE-126: Buffer Over-read •
