A vulnerability in the DECnet Phase IV and DECnet/OSI protocol processing of Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to insufficient input validation of DECnet traffic that is received by an affected device. An attacker could exploit this vulnerability by sending DECnet traffic to an affected device. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition.

A vulnerability in the web-based management interface of Cisco IOS XE Wireless Controller software for the Catalyst 9000 Family of switches could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against another user of the web-based management interface of an affected device. The vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of an affected device. An attacker could exploit this vulnerability by authenticating to the device as a high-privileged user, adding certain configurations with malicious code in one of its fields, and persuading another user to click on it. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or to access sensitive, browser-based information. Una vulnerabilidad en la interfaz de administración basada en web del software Cisco IOS XE Wireless Controller para la Familia Catalyst 9000, podría permitir a un atacante remoto autenticado llevar a cabo un ataque de tipo cross-site scripting (XSS) contra otro usuario de la interfaz de administración basada en web de un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ewlc-xss-cAfMtCzv • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

A vulnerability in Address Resolution Protocol (ARP) management of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to prevent an affected device from resolving ARP entries for legitimate hosts on the connected subnets. This vulnerability exists because ARP entries are mismanaged. An attacker could exploit this vulnerability by continuously sending traffic that results in incomplete ARP entries. A successful exploit could allow the attacker to cause ARP requests on the device to be unsuccessful for legitimate hosts, resulting in a denial of service (DoS) condition. Una vulnerabilidad en la administración del Address Resolution Protocol (ARP) del Software Cisco IOS y el Software Cisco IOS XE, podría permitir a un atacante remoto no autenticado impedir que un dispositivo afectado resuelva entradas ARP para hosts legítimos en las subredes conectadas. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-arp-mtfhBfjE • CWE-399: Resource Management Errors •

CVSS: 7.2EPSS: 0%CPEs: 74EXPL: 0

A vulnerability in one of the diagnostic test CLI commands of Cisco IOS XE Software could allow an authenticated, local attacker to execute arbitrary code on an affected device. To exploit this vulnerability, the attacker would need to have valid user credentials at privilege level 15. This vulnerability exists because the affected software permits modification of the run-time memory of an affected device under specific circumstances. An attacker could exploit this vulnerability by authenticating to the affected device and issuing a specific diagnostic test command at the CLI. A successful exploit could trigger a logic error in the code that was designed to restrict run-time memory modifications. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-XE-OFP-6Nezgn7b • CWE-123: Write-what-where Condition •

A vulnerability in the dragonite debugger of Cisco IOS XE Software could allow an authenticated, local attacker to escalate from privilege level 15 to root privilege. The vulnerability is due to the presence of development testing and verification scripts that remained on the device. An attacker could exploit this vulnerability by bypassing the consent token mechanism with the residual scripts on the affected device. A successful exploit could allow the attacker to escalate from privilege level 15 to root privilege. Una vulnerabilidad en el depurador dragonite del Software Cisco IOS XE, podría permitir a un atacante local autenticado escalar del nivel de privilegio 15 al privilegio de root. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-XE-FSM-Yj8qJbJc • CWE-489: Active Debug Code •
