CVSS v3.1 |
| Memory leak in Cisco IOS before 15.0(1)XA5 might allow remote attackers to cause a denial of service (memory consumption) by sending a crafted SIP REGISTER message over UDP, aka Bug ID CSCtg41733. |
| Cisco IOS before 15.0(1)XA does not properly handle IRC traffic during a specific time period after an initial reload, which allows remote attackers to cause a denial of service (device reload) via an attempted connection to a certain IRC server, related to a "corrupted magic value," aka Bug ID CSCso05336. |
| The NETIO and IPV4_IO processes in Cisco IOS XR 3.8 through 4.1, as used in Cisco Carrier Routing System and other products, allow remote attackers to cause a denial of service (CPU consumption) via crafted network traffic, aka Bug ID CSCti59888. |
| Cisco IOS 15.1(2)T allows remote attackers to cause a denial of service (resource consumption and TCP outage) via spoofed TCP packets, related to embryonic TCP connections that remain in the SYN_RCVD or SYN_SENT state, aka Bug ID CSCti18193. |
| Unspecified vulnerability in the NAT for H.323 implementation in Cisco IOS 12.1 through 12.4 and 15.0 through 15.1 allows remote attackers to cause a denial of service (device reload) via transit traffic, aka Bug ID CSCtf91428. |
| Memory leak in the SSL VPN feature in Cisco IOS 12.4, 15.0, and 15.1, when HTTP port redirection is enabled, allows remote attackers to cause a denial of service (memory consumption) by improperly disconnecting SSL sessions, leading to connections that remain in the CLOSE-WAIT state, aka Bug ID CSCtg21685. |
| Cisco IOS 12.2 through 12.4 and 15.0 through 15.1, Cisco IOS XE 2.5.x and 2.6.x before 2.6.1, and Cisco Unified Communications Manager (aka CUCM, formerly CallManager) 6.x before 6.1(5), 7.0 before 7.0(2a)su3, 7.1su before 7.1(3b)su2, 7.1 before 7.1(5), and 8.0 before 8.0(1) allow remote attackers to cause a denial of service (device reload or voice-services outage) via a SIP REFER request with an invalid Refer-To header, aka Bug IDs CSCta20040 and CSCta31358. |
| Cisco IOS 12.2 through 12.4 and 15.0 through 15.1, Cisco IOS XE 2.5.x and 2.6.x before 2.6.1, and Cisco Unified Communications Manager (aka CUCM, formerly CallManager) 6.x before 6.1(5)SU1, 7.x before 7.1(5), and 8.0 before 8.0(2) allow remote attackers to cause a denial of service (device reload or voice-services outage) via crafted SIP registration traffic over UDP, aka Bug IDs CSCtf72678 and CSCtf14987. |
| The Neighbor Discovery (ND) protocol implementation in the IPv6 stack in Cisco IOS before 15.0(1)XA5 allows remote attackers to cause a denial of service (CPU consumption and device hang) by sending many Router Advertisement (RA) messages with different source addresses, as demonstrated by the flood_router6 program in the thc-ipv6 package, aka Bug ID CSCti33534. |
| CallManager Express (CME) on Cisco IOS before 15.0(1)XA1 does not properly handle SIP TRUNK traffic that contains rate bursts and a "peculiar" request size, which allows remote attackers to cause a denial of service (memory consumption) by sending this traffic over a long duration, aka Bug ID CSCtb47950. |
| STCAPP (aka the SCCP telephony control application) on Cisco IOS before 15.0(1)XA1 does not properly handle multiple calls to a shared line, which allows remote attackers to cause a denial of service (port hang) by simultaneously ending two calls that were controlled by CallManager Express (CME), aka Bug ID CSCtd42552. |
| Unspecified vulnerability in the NAT for H.225.0 implementation in Cisco IOS 12.1 through 12.4 and 15.0 through 15.1 allows remote attackers to cause a denial of service (device reload) via transit traffic, aka Bug ID CSCtd86472. |
| Unspecified vulnerability in the NAT for SIP implementation in Cisco IOS 12.1 through 12.4 and 15.0 through 15.1 allows remote attackers to cause a denial of service (device reload) via transit traffic on UDP port 5060, aka Bug ID CSCtf17624. |
| The IGMPv3 implementation in Cisco IOS 12.2, 12.3, 12.4, and 15.0 and IOS XE 2.5.x before 2.5.2, when PIM is enabled, allows remote attackers to cause a denial of service (device reload) via a malformed IGMP packet, aka Bug ID CSCte14603. |
| Unspecified vulnerability in the H.323 implementation in Cisco IOS 12.1 through 12.4 and 15.0 through 15.1, and IOS XE 2.5.x before 2.5.2 and 2.6.x before 2.6.1, allows remote attackers to cause a denial of service (traceback and device reload) via crafted H.323 packets, aka Bug ID CSCtd33567. |
| Unspecified vulnerability in Cisco IOS 12.4(24)MD before 12.4(24)MD2 on the Cisco Content Services Gateway Second Generation (aka CSG2) allows remote attackers to cause a denial of service (device hang or reload) via crafted TCP packets, aka Bug ID CSCth41891, a different vulnerability than CVE-2011-0349. |
| Unspecified vulnerability in the H.323 implementation in Cisco IOS 12.1 through 12.4 and 15.0 through 15.1, and IOS XE 2.5.x before 2.5.2 and 2.6.x before 2.6.1, allows remote attackers to cause a denial of service (device reload) via crafted H.323 packets, aka Bug ID CSCtc73759. |
| 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 the file system permissions of Cisco IOS XE Software could allow an authenticated, local attacker to obtain read and write access to critical configuration or system files. The vulnerability is due to insufficient file system permissions on an affected device. An attacker could exploit this vulnerability by connecting to an affected device's guest shell, and accessing or modifying restricted files. A successful exploit could allow the attacker to view or modify restricted information or configurations that are normally not accessible to system administrators. |
