CVSS v3.1 |
| Cisco IOS 12.1 through 12.4, and 15.0M before 15.0(1)M1, allows remote attackers to cause a denial of service (interface queue wedge) via malformed H.323 packets, aka Bug ID CSCta19962. |
| The PKI functionality in Cisco IOS 15.0 and 15.1 does not prevent permanent caching of certain public keys, which allows remote attackers to bypass authentication and have unspecified other impact by leveraging an IKE peer relationship in which a key was previously valid but later revoked, aka Bug ID CSCth82164, a different vulnerability than CVE-2010-4685. |
| Cisco IOS 12.4(24)MDB9 and earlier on Content Services Gateway (CSG) devices does not properly implement the "parse error drop" feature, which allows remote attackers to bypass intended access restrictions via a crafted series of packets, aka Bug ID CSCug90143. |
| Multiple memory leaks in Cisco IOS 15.1 before 15.1(4)M7 allow remote attackers to cause a denial of service (memory consumption or device reload) by sending a crafted SIP message over (1) IPv4 or (2) IPv6, aka Bug IDs CSCuc42558 and CSCug25383. |
| Cisco IOS XR 3.8.1 through 4.2.0 does not properly process fragmented packets within the RP-A, RP-B, PRP, and DRP-B route-processor components, which allows remote attackers to cause a denial of service (transmission outage) via (1) IPv4 or (2) IPv6 traffic, aka Bug ID CSCuh30380. |
| The IKEv2 implementation in Cisco IOS, when AES-GCM or AES-GMAC is used, allows remote attackers to bypass certain IPsec anti-replay features via IPsec tunnel traffic, aka Bug ID CSCuj47795. |
| The OSPFv3 functionality in Cisco IOS XR 5.1 allows remote attackers to cause a denial of service (process crash) via a malformed LSA Type-1 packet, aka Bug ID CSCuj82176. |
| The TCP reassembly feature in Cisco IOS XE 3.7 before 3.7.3S and 3.8 before 3.8.1S on 1000 ASR devices allows remote attackers to cause a denial of service (device reload) via large TCP packets that are processed by the (1) NAT or (2) ALG component, aka Bug ID CSCud72509. |
| The PPTP ALG implementation in Cisco IOS XE 3.9 before 3.9.2S on 1000 ASR devices allows remote attackers to cause a denial of service (device reload) by sending many PPTP packets over NAT, aka Bug ID CSCuh19936. |
| Memory leak in the Zone-Based Firewall in Cisco IOS 12.4, 15.0, 15.1, and 15.2 allows remote attackers to cause a denial of service (memory consumption or device reload) via crafted IP packets, aka Bug ID CSCto89536. |
| The OSPF functionality in Cisco IOS and IOS XE allows remote attackers to cause a denial of service (device reload) via crafted options in an LSA type 11 packet, aka Bug ID CSCui21030. |
| Cisco IOS on Catalyst 3750X switches has default Service Module credentials, which makes it easier for local users to gain privileges via a Service Module login, aka Bug ID CSCue92286. |
| The UDP process in Cisco IOS XR 4.3.1 does not free packet memory upon detecting full packet queues, which allows remote attackers to cause a denial of service (memory consumption) via UDP packets to listening ports, aka Bug ID CSCue69413. |
| The remember feature in the DHCP server in Cisco IOS allows remote attackers to cause a denial of service (device reload) by acquiring a lease and then sending a DHCPRELEASE message, aka Bug ID CSCuh46822. |
| The PPTP-ALG component in CRS Carrier Grade Services Engine (CGSE) and ASR 9000 Integrated Service Module (ISM) in Cisco IOS XR allows remote attackers to cause a denial of service (module reset) via crafted packet streams, aka Bug ID CSCue91963. |
| The T1/E1 driver-queue functionality in Cisco IOS 12.2 and 15.0 through 15.3, when an HDLC32 driver is used, allows remote attackers to cause a denial of service (interface queue wedge) via bursty network traffic, aka Bug ID CSCub67465. |
| The Zone-Based Firewall (ZFW) feature in Cisco IOS 15.1 through 15.2, when content filtering or HTTP ALG inspection is enabled, allows remote attackers to cause a denial of service (device reload or hang) via crafted IPv4 HTTP traffic, aka Bug ID CSCtx56174. |
| A vulnerability in the application-hosting subsystem of Cisco IOS XE Software could allow an authenticated, local attacker to elevate privileges to root on an affected device. The attacker could execute IOS XE commands outside the application-hosting subsystem Docker container as well as on the underlying Linux operating system. These commands could be run as the root user. The vulnerability is due to a combination of two factors: (a) incomplete input validation of the user payload of CLI commands, and (b) improper role-based access control (RBAC) when commands are issued at the command line within the application-hosting subsystem. An attacker could exploit this vulnerability by using a CLI command with crafted user input. A successful exploit could allow the lower-privileged attacker to execute arbitrary CLI commands with root privileges. The attacker would need valid user credentials to exploit this vulnerability. |
| A vulnerability in the multicast DNS (mDNS) feature of Cisco IOS XE Software for Cisco Catalyst 9800 Series Wireless Controllers could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition. The vulnerability is due to improper validation of mDNS packets. An attacker could exploit this vulnerability by sending a crafted mDNS packet to an affected device. A successful exploit could cause a device to reload, resulting in a DoS condition. |
| A vulnerability in Simple Network Management Protocol (SNMP) trap generation for wireless clients of the Cisco IOS XE Wireless Controller Software for the Cisco Catalyst 9000 Family could allow an unauthenticated, adjacent attacker to cause the device to unexpectedly reload, causing a denial of service (DoS) condition on an affected device. The vulnerability is due to the lack of input validation of the information used to generate an SNMP trap in relation to a wireless client connection. An attacker could exploit this vulnerability by sending an 802.1x packet with crafted parameters during the wireless authentication setup phase of a connection. A successful exploit could allow the attacker to cause the device to reload, causing a DoS condition. |
