Security Vulnerabilities
- CVEs Published In September 2023
A vulnerability in the command line interface (cli) management interface of Cisco SD-WAN vManage could allow an authenticated, local attacker to bypass authorization and allow the attacker to roll back the configuration on vManage controllers and edge router device.
This vulnerability is due to improper access control in the cli-management interface of an affected system. An attacker with low-privilege (read only) access to the cli could exploit this vulnerability by sending a request to roll back the configuration on for other controller and devices managed by an affected system. A successful exploit could allow the attacker to to roll back the configuration on for other controller and devices managed by an affected system.
A vulnerability in the session management system of the Cisco Catalyst SD-WAN Manager multi-tenant feature could allow an authenticated, remote attacker to access another tenant that is being managed by the same Cisco Catalyst SD-WAN Manager instance. This vulnerability requires the multi-tenant feature to be enabled.
This vulnerability is due to insufficient user session management within the Cisco Catalyst SD-WAN Manager system. An attacker could exploit this vulnerability by sending a crafted request to an affected system. A successful exploit could allow the attacker to gain unauthorized access to information about another tenant, make configuration changes, or possibly take a tenant offline causing a denial of service condition.
A vulnerability in the SSH service of Cisco Catalyst SD-WAN Manager could allow an unauthenticated, remote attacker to cause a process crash, resulting in a DoS condition for SSH access only. This vulnerability does not prevent the system from continuing to function, and web UI access is not affected.
This vulnerability is due to insufficient resource management when an affected system is in an error condition. An attacker could exploit this vulnerability by sending malicious traffic to the affected system. A successful exploit could allow the attacker to cause the SSH process to crash and restart, resulting in a DoS condition for the SSH service.
A vulnerability in the packet processing functionality of Cisco access point (AP) software could allow an unauthenticated, adjacent attacker to exhaust resources on an affected device.
This vulnerability is due to insufficient management of resources when handling certain types of traffic. An attacker could exploit this vulnerability by sending a series of specific wireless packets to an affected device. A successful exploit could allow the attacker to consume resources on an affected device. A sustained attack could lead to the disruption of the Control and Provisioning of Wireless Access Points (CAPWAP) tunnel and intermittent loss of wireless client traffic.
xrdp is an open source remote desktop protocol server. Access to the font glyphs in xrdp_painter.c is not bounds-checked . Since some of this data is controllable by the user, this can result in an out-of-bounds read within the xrdp executable. The vulnerability allows an out-of-bounds read within a potentially privileged process. On non-Debian platforms, xrdp tends to run as root. Potentially an out-of-bounds write can follow the out-of-bounds read. There is no denial-of-service impact, providing xrdp is running in forking mode. This issue has been addressed in release 0.9.23.1. Users are advised to upgrade. There are no known workarounds for this vulnerability.
Two potential signed to unsigned conversion errors and buffer overflow vulnerabilities at the following locations in the Zephyr IPM drivers.
A vulnerability in Cisco IOS XE Software for Cisco Catalyst 3650 and Catalyst 3850 Series Switches could allow an unauthenticated, remote attacker to cause an affected device to reload unexpectedly, resulting in a denial of service (DoS) condition.
This vulnerability is due to improper resource management when processing traffic that is received on the management interface. An attacker could exploit this vulnerability by sending a high rate of traffic to the management interface. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition.
Vulnerability in the Elasticsearch database used in the of Cisco SD-WAN vManage software could allow an unauthenticated, remote attacker to access the Elasticsearch configuration database of an affected device with the privileges of the elasticsearch user.
These vulnerability is due to the presence of a static username and password configured on the vManage. An attacker could exploit this vulnerability by sending a crafted HTTP request to a reachable vManage on port 9200. A successful exploit could allow the attacker to view the Elasticsearch database content.
There are workarounds that address this vulnerability.
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 cause the affected system to reload, resulting in a denial of service (DoS) condition. For more information, see the Details ["#details"] section of this advisory.
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.
