Cisco IOS 12.2 and 12.3 on Cisco uBR10012 series devices, when linecard redundancy is configured, enables a read/write SNMP service with "private" as the community, which allows remote attackers to obtain administrative access by guessing this community and sending SNMP requests.
CVE-2009-2868 1 Cisco 1 Ios 2025-04-09 7.8 HIGH N/A
Unspecified vulnerability in Cisco IOS 12.2 through 12.4, when certificate-based authentication is enabled for IKE, allows remote attackers to cause a denial of service (Phase 1 SA exhaustion) via crafted requests, aka Bug IDs CSCsy07555 and CSCee72997.
CVE-2008-1156 1 Cisco 2 Cisco Ios, Ios 2025-04-09 5.1 MEDIUM N/A
Unspecified vulnerability in the Multicast Virtual Private Network (MVPN) implementation in Cisco IOS 12.0, 12.2, 12.3, and 12.4 allows remote attackers to create "extra multicast states on the core routers" via a crafted Multicast Distribution Tree (MDT) Data Join message.
CVE-2007-4286 1 Cisco 1 Ios 2025-04-09 9.3 HIGH N/A
Buffer overflow in the Next Hop Resolution Protocol (NHRP) functionality in Cisco IOS 12.0 through 12.4 allows remote attackers to cause a denial of service (restart) and execute arbitrary code via a crafted NHRP packet.
CVE-2008-3810 1 Cisco 1 Ios 2025-04-09 7.8 HIGH N/A
Cisco IOS 12.2 and 12.4, when NAT Skinny Call Control Protocol (SCCP) Fragmentation Support is enabled, allows remote attackers to cause a denial of service (device reload) via segmented SCCP messages, aka CSCsg22426, a different vulnerability than CVE-2008-3811.
CVE-2009-2873 1 Cisco 1 Ios 2025-04-09 7.1 HIGH N/A
Cisco IOS 12.0 through 12.4, when IP-based tunnels and the Cisco Express Forwarding feature are enabled, allows remote attackers to cause a denial of service (device reload) via malformed packets, aka Bug ID CSCsx70889.
CVE-2008-3808 1 Cisco 1 Ios 2025-04-09 7.8 HIGH N/A
Unspecified vulnerability in Cisco IOS 12.0 through 12.4 allows remote attackers to cause a denial of service (device reload) via a crafted Protocol Independent Multicast (PIM) packet.
CVE-2008-3805 1 Cisco 1 Ios 2025-04-09 8.5 HIGH N/A
Cisco IOS 12.0 through 12.4 on Cisco 10000, uBR10012 and uBR7200 series devices handles external UDP packets that are sent to 127.0.0.0/8 addresses intended for IPC communication within the device, which allows remote attackers to cause a denial of service (device or linecard reload) via crafted UDP packets, a different vulnerability than CVE-2008-3806.
CVE-2007-5549 1 Cisco 1 Ios 2025-04-09 2.1 LOW N/A
Unspecified vulnerability in Command EXEC in Cisco IOS allows local users to bypass command restrictions and obtain sensitive information via an unspecified "variation of an IOS command" involving "two different methods", aka CSCsk16129. NOTE: as of 20071016, the only disclosure is a vague pre-advisory with no actionable information. However, since it is from a well-known researcher, it is being assigned a CVE identifier for tracking purposes.
CVE-2007-2688 1 Cisco 2 Ios, Ips Sensor Software 2025-04-09 7.8 HIGH N/A
The Cisco Intrusion Prevention System (IPS) and IOS with Firewall/IPS Feature Set do not properly handle certain full-width and half-width Unicode character encodings, which might allow remote attackers to evade detection of HTTP traffic.
CVE-2009-0636 1 Cisco 1 Ios 2025-04-09 7.8 HIGH N/A
Unspecified vulnerability in Cisco IOS 12.0 through 12.4, when SIP voice services are enabled, allows remote attackers to cause a denial of service (device crash) via a valid SIP message.
CVE-2008-3821 1 Cisco 1 Ios 2025-04-09 4.3 MEDIUM N/A
Multiple cross-site scripting (XSS) vulnerabilities in the HTTP server in Cisco IOS 11.0 through 12.4 allow remote attackers to inject arbitrary web script or HTML via (1) the query string to the ping program or (2) unspecified other aspects of the URI.
CVE-2007-4263 1 Cisco 1 Ios 2025-04-09 8.5 HIGH N/A
Unspecified vulnerability in the server side of the Secure Copy (SCP) implementation in Cisco 12.2-based IOS allows remote authenticated users to read, write or overwrite any file on the device's filesystem via unknown vectors.
CVE-2007-0917 1 Cisco 1 Ios 2025-04-09 6.4 MEDIUM N/A
The Intrusion Prevention System (IPS) feature for Cisco IOS 12.4XE to 12.3T allows remote attackers to bypass IPS signatures that use regular expressions via fragmented packets.
CVE-2007-4292 1 Cisco 1 Ios 2025-04-09 9.3 HIGH N/A
Multiple memory leaks in Cisco IOS 12.0 through 12.4 allow remote attackers to cause a denial of service (device crash) via a malformed SIP packet, aka (1) CSCsf11855, (2) CSCeb21064, (3) CSCse40276, (4) CSCse68355, (5) CSCsf30058, (6) CSCsb24007, and (7) CSCsc60249.
