CVE-1999-0230 1 Cisco 1 Ios 2008-09-09 5.0 MEDIUM N/A
Buffer overflow in Cisco 7xx routers through the telnet service.
CVE-1999-0160 1 Cisco 1 Ios 2008-09-09 7.5 HIGH N/A
Some classic Cisco IOS devices have a vulnerability in the PPP CHAP authentication to establish unauthorized PPP connections.
CVE-1999-0016 6 Cisco, Gnu, Hp and 3 more 8 Ios, Inet, Hp-ux and 5 more 2008-09-09 5.0 MEDIUM N/A
Land IP denial of service.
CVE-1999-0161 1 Cisco 1 Ios 2008-09-09 7.5 HIGH N/A
In Cisco IOS 10.3, with the tacacs-ds or tacacs keyword, an extended IP access control list could bypass filtering.
CVE-2007-5550 1 Cisco 1 Ios 2008-09-05 5.0 MEDIUM N/A
Unspecified vulnerability in Cisco IOS allows remote attackers to obtain the IOS version via unspecified vectors involving a "common network service", aka PSIRT-1255024833. 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-2007-5551 1 Cisco 1 Ios 2008-09-05 7.1 HIGH N/A
Off-by-one error in Cisco IOS allows remote attackers to execute arbitrary code via unspecified vectors that trigger a heap-based buffer overflow. 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-2007-5552 1 Cisco 1 Ios 2008-09-05 9.3 HIGH N/A
Integer overflow in Cisco IOS allows remote attackers to execute arbitrary code via unspecified vectors. 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-2002-2053 1 Cisco 1 Ios 2008-09-05 5.0 MEDIUM N/A
The design of the Hot Standby Routing Protocol (HSRP), as implemented on Cisco IOS 12.1, when using IRPAS, allows remote attackers to cause a denial of service (CPU consumption) via a router with the same IP address as the interface on which HSRP is running, which causes a loop.
CVE-2002-2052 1 Cisco 1 Ios 2008-09-05 5.0 MEDIUM N/A
Cisco 2611 router running IOS 12.1(6.5), possibly an interim release, allows remote attackers to cause a denial of service via port scans such as (1) scanning all ports on a single host and (2) scanning a network of hosts for a single open port through the router. NOTE: the vendor could not reproduce this issue, saying that the original reporter was using an interim release of the software.
CVE-2002-2315 1 Cisco 1 Ios 2008-09-05 7.8 HIGH N/A
Cisco IOS 11.2.x and 12.0.x does not limit the size of its redirect table, which allows remote attackers to cause a denial of service (memory consumption) via spoofed ICMP redirect packets to the router.
CVE-2002-0339 1 Cisco 1 Ios 2008-09-05 5.0 MEDIUM N/A
Cisco IOS 11.1CC through 12.2 with Cisco Express Forwarding (CEF) enabled includes portions of previous packets in the padding of a MAC level packet when the MAC packet's length is less than the IP level packet length.
CVE-2001-0288 1 Cisco 1 Ios 2008-09-05 7.5 HIGH N/A
Cisco switches and routers running IOS 12.1 and earlier produce predictable TCP Initial Sequence Numbers (ISNs), which allows remote attackers to spoof or hijack TCP connections.
CVE-2000-0700 1 Cisco 4 Gigabit Switch Router 12008, Gigabit Switch Router 12012, Gigabit Switch Router 12016 and 1 more 2008-09-05 5.0 MEDIUM N/A
Cisco Gigabit Switch Routers (GSR) with Fast Ethernet / Gigabit Ethernet cards, from IOS versions 11.2(15)GS1A up to 11.2(19)GS0.2 and some versions of 12.0, do not properly handle line card failures, which allows remote attackers to bypass ACLs or force the interface to stop forwarding packets.
CVE-1999-1306 1 Cisco 1 Ios 2008-09-05 7.5 HIGH N/A
Cisco IOS 9.1 and earlier does not properly handle extended IP access lists when the IP route cache is enabled and the "established" keyword is set, which could allow attackers to bypass filters.
CVE-1999-1466 1 Cisco 1 Ios 2008-09-05 7.5 HIGH N/A
Vulnerability in Cisco routers versions 8.2 through 9.1 allows remote attackers to bypass access control lists when extended IP access lists are used on certain interfaces, the IP route cache is enabled, and the access list uses the "established" keyword.
