https://sec.cloudapps.cisco.com/security/center/content/Cisc...
A vulnerability in the memory buffer of Cisco Wireless LAN Controller (WLC) AireOS Software could allow an unauthenticated, adjacent attacker to cause memory leaks that could eventually lead to a device reboot.
This vulnerability is due to memory leaks caused by multiple clients connecting under specific conditions. An attacker could exploit this vulnerability by causing multiple wireless clients to attempt to connect to an access point (AP) on an affected device. A successful exploit could allow the attacker to cause the affected device to reboot after a significant amount of time, resulting in a denial of service (DoS) condition.
Cisco has released software updates that address this vulnerability. There is a workaround that addresses this vulnerability.

Cisco Catalyst 9100 Access Points Denial of Service Vulnerability
> date : 2023-09-27 16:00:00

https://sec.cloudapps.cisco.com/security/center/content/Cisc...
A vulnerability in the networking component of Cisco access point (AP) software could allow an unauthenticated, remote attacker to cause a temporary disruption of service.
This vulnerability is due to overuse of AP resources. An attacker could exploit this vulnerability by connecting to an AP on an affected device as a wireless client and sending a high rate of traffic over an extended period of time. A successful exploit could allow the attacker to cause the Datagram TLS (DTLS) session to tear down and reset, causing a denial of service (DoS) condition.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

A vulnerability in Cisco DNA Center could allow an unauthenticated, remote attacker to read and modify data in a repository that belongs to an internal service on an affected device.
This vulnerability is due to insufficient access control enforcement on API requests. An attacker could exploit this vulnerability by sending a crafted API request to an affected device. A successful exploit could allow the attacker to read and modify data that is handled by an internal service on the affected device.
Cisco has released software updates that address this vulnerability. There are workarounds that address this vulnerability.

Cisco IOS and IOS XE Software Cisco Group Encrypted Transport VPN Software Out-of-Bounds Write Vulnerability
> date : 2023-09-27 16:00:00
> lien :
https://sec.cloudapps.cisco.com/security/center/content/Cisc...
A vulnerability in the Cisco Group Encrypted Transport VPN (GET VPN) feature of Cisco IOS Software and Cisco IOS XE Software could allow an authenticated, remote attacker who has administrative control of either a group member or a key server to execute arbitrary code on an affected device or cause the device to crash.
This vulnerability is due to insufficient validation of attributes in the Group Domain of Interpretation (GDOI) and G-IKEv2 protocols of the GET VPN feature. An attacker could exploit this vulnerability by either compromising an installed key server or modifying the configuration of a group member to point to a key server that is controlled by the attacker. A successful exploit could allow the attacker to execute arbitrary code and gain full control of the affected system or [...]
