CVSS: 5.3EPSS: 0%CPEs: 28EXPL: 0CVE-2022-20766 – Cisco ATA 190 Series Analog Telephone Adapter firmware Cisco Discovery Protocol Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2022-20766
A vulnerability in the Cisco Discovery Protocol functionality of Cisco ATA 190 Series Adaptive Telephone Adapter firmware could allow an unauthenticated, remote attacker to cause a DoS condition on an affected device. This vulnerability is due to an out-of-bounds read when processing Cisco Discovery Protocol packets. An attacker could exploit this vulnerability by sending crafted Cisco Discovery Protocol packets to an affected device. A successful exploit could allow the attacker to cause a service restart.Cisco has released firmware updates that address this vulnerability. There are no workarounds that address this vulnerability. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ata19x-multivuln-GEZYVvs • CWE-125: Out-of-bounds Read •
CVSS: 4.3EPSS: 0%CPEs: 60EXPL: 0CVE-2022-20846 – Cisco IOS XR Software Cisco Discovery Protocol Buffer Overflow Vulnerability
https://notcve.org/view.php?id=CVE-2022-20846
A vulnerability in the Cisco Discovery Protocol implementation for Cisco IOS XR Software could allow an unauthenticated, adjacent attacker to cause the Cisco Discovery Protocol process to reload on an affected device. This vulnerability is due to a heap buffer overflow in certain Cisco Discovery Protocol messages. 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 cause a heap overflow, which could cause the Cisco Discovery Protocol process to reload on the device. The bytes that can be written in the buffer overflow are restricted, which limits remote code execution.Note: Cisco Discovery Protocol is a Layer 2 protocol. To exploit this vulnerability, an attacker must be in the same broadcast domain as the affected device (Layer 2 adjacent). • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-xr-cdp-wnALzvT2 https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxr-bng-Gmg5Gxt https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ncs4k-tl1-GNnLwC6 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
CVSS: 6.0EPSS: 0%CPEs: 6EXPL: 0CVE-2022-20845 – Cisco Network Convergence System 4000 Series TL1 Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2022-20845
A vulnerability in the TL1 function of Cisco Network Convergence System (NCS) 4000 Series could allow an authenticated, local attacker to cause a memory leak in the TL1 process. This vulnerability is due to TL1 not freeing memory under some conditions. An attacker could exploit this vulnerability by connecting to the device and issuing TL1 commands after being authenticated. A successful exploit could allow the attacker to cause the TL1 process to consume large amounts of memory. When the memory reaches a threshold, the Resource Monitor (Resmon) process will begin to restart or shutdown the top five consumers of memory, resulting in a denial of service (DoS).Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.This advisory is part of the September 2022 release of the Cisco IOS XR Software Security Advisory Bundled Publication. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ncs4k-tl1-GNnLwC6 https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxr-bng-Gmg5Gxt • CWE-789: Memory Allocation with Excessive Size Value •
CVSS: 6.1EPSS: 0%CPEs: 33EXPL: 0CVE-2022-20849 – Cisco IOS XR Software Broadband Network Gateway PPPoE Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2022-20849
A vulnerability in the Broadband Network Gateway PPP over Ethernet (PPPoE) feature of Cisco IOS XR Software could allow an unauthenticated, adjacent attacker to cause the PPPoE process to continually crash. This vulnerability exists because the PPPoE feature does not properly handle an error condition within a specific crafted packet sequence. An attacker could exploit this vulnerability by sending a sequence of specific PPPoE packets from controlled customer premises equipment (CPE). A successful exploit could allow the attacker to cause the PPPoE process to continually restart, resulting in a denial of service condition (DoS).Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.This advisory is part of the September 2022 release of the Cisco IOS XR Software Security Advisory Bundled Publication.

https://notcve.org/view.php?id=CVE-2022-20939
A vulnerability in the web-based management interface of Cisco Smart Software Manager On-Prem could allow an authenticated, remote attacker to elevate privileges on an affected system. This vulnerability is due to inadequate protection of sensitive user information. An attacker could exploit this vulnerability by accessing certain logs on an affected system. A successful exploit could allow the attacker to use the obtained information to elevate privileges to System Admin.Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-bw-thinrcpt-xss-gSj4CecU https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-cssm-priv-esc-SEjz69dv • CWE-922: Insecure Storage of Sensitive Information •
