CVE-2001-1071 1 Cisco 2 Catos, Ios 2024-02-28 5.0 MEDIUM N/A
Cisco IOS 12.2 and earlier running Cisco Discovery Protocol (CDP) allows remote attackers to cause a denial of service (memory consumption) via a flood of CDP neighbor announcements.
CVE-1999-0016 6 Cisco, Gnu, Hp and 3 more 8 Ios, Inet, Hp-ux and 5 more 2024-02-28 5.0 MEDIUM N/A
Land IP denial of service.
CVE-2002-1357 7 Cisco, Fissh, Intersoft and 4 more 7 Ios, Ssh Client, Securenetterm and 4 more 2024-02-28 10.0 HIGH N/A
Multiple SSH2 servers and clients do not properly handle packets or data elements with incorrect length specifiers, which may allow remote attackers to cause a denial of service or possibly execute arbitrary code, as demonstrated by the SSHredder SSH protocol test suite.
CVE-2001-0288 1 Cisco 1 Ios 2024-02-28 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-1999-0162 1 Cisco 1 Ios 2024-02-28 5.0 MEDIUM N/A
The "established" keyword in some Cisco IOS software allowed an attacker to bypass filtering.
CVE-2001-1434 1 Cisco 1 Ios 2024-02-28 5.0 MEDIUM N/A
Cisco IOS 12.0(5)XU through 12.1(2) allows remote attackers to read system administration and topology information via an "snmp-server host" command, which creates a readable "community" community string if one has not been previously created.
CVE-2004-0054 1 Cisco 1 Ios 2024-02-28 7.5 HIGH N/A
Multiple vulnerabilities in the H.323 protocol implementation for Cisco IOS 11.3T through 12.2T allow remote attackers to cause a denial of service and possibly execute arbitrary code, as demonstrated by the NISCC/OUSPG PROTOS test suite for the H.225 protocol.
CVE-2003-0512 1 Cisco 1 Ios 2024-02-28 5.0 MEDIUM N/A
Cisco IOS 12.2 and earlier generates a "% Login invalid" message instead of prompting for a password when an invalid username is provided, which allows remote attackers to identify valid usernames on the system and conduct brute force password guessing, as reported for the Aironet Bridge.
CVE-2002-2239 1 Cisco 3 Catalyst 6500, Catalyst 7600, Ios 2024-02-28 7.8 HIGH N/A
The Cisco Optical Service Module (OSM) for the Catalyst 6500 and 7600 series running Cisco IOS 12.1(8)E through 12.1(13.4)E allows remote attackers to cause a denial of service (hang) via a malformed packet.
CVE-2002-1359 7 Cisco, Fissh, Intersoft and 4 more 7 Ios, Ssh Client, Securenetterm and 4 more 2024-02-28 10.0 HIGH N/A
Multiple SSH2 servers and clients do not properly handle large packets or large fields, which may allow remote attackers to cause a denial of service or possibly execute arbitrary code via buffer overflow attacks, as demonstrated by the SSHredder SSH protocol test suite.
CVE-2004-0244 1 Cisco 1 Ios 2024-02-28 4.7 MEDIUM N/A
Cisco 6000, 6500, and 7600 series systems with Multilayer Switch Feature Card 2 (MSFC2) and a FlexWAN or OSM module allow local users to cause a denial of service (hang or reset) by sending a layer 2 frame packet that encapsulates a layer 3 packet, but has inconsistent length values with that packet.
CVE-2002-1706 1 Cisco 3 Ios, Ubr7100, Ubr7200 2024-02-28 5.0 MEDIUM 7.5 HIGH
Cisco IOS software 11.3 through 12.2 running on Cisco uBR7200 and uBR7100 series Universal Broadband Routers allows remote attackers to modify Data Over Cable Service Interface Specification (DOCSIS) settings via a DOCSIS file without a Message Integrity Check (MIC) signature, which is approved by the router.
CVE-2004-0112 24 4d, Apple, Avaya and 21 more 65 Webstar, Mac Os X, Mac Os X Server and 62 more 2024-02-28 5.0 MEDIUM N/A
The SSL/TLS handshaking code in OpenSSL 0.9.7a, 0.9.7b, and 0.9.7c, when using Kerberos ciphersuites, does not properly check the length of Kerberos tickets during a handshake, which allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that causes an out-of-bounds read.
CVE-2003-1109 1 Cisco 4 Ios, Ip Phone 7940, Ip Phone 7960 and 1 more 2024-02-28 7.5 HIGH N/A
The Session Initiation Protocol (SIP) implementation in multiple Cisco products including IP Phone models 7940 and 7960, IOS versions in the 12.2 train, and Secure PIX 5.2.9 to 6.2.2 allows remote attackers to cause a denial of service and possibly execute arbitrary code via crafted INVITE messages, as demonstrated by the OUSPG PROTOS c07-sip test suite.
CVE-1999-1175 1 Cisco 1 Ios 2024-02-28 7.5 HIGH N/A
Web Cache Control Protocol (WCCP) in Cisco Cache Engine for Cisco IOS 11.2 and earlier does not use authentication, which allows remote attackers to redirect HTTP traffic to arbitrary hosts via WCCP packets to UDP port 2048.
CVE-1999-0445 1 Cisco 1 Ios 2024-02-28 5.0 MEDIUM N/A
In Cisco routers under some versions of IOS 12.0 running NAT, some packets may not be filtered by input access list filters.
CVE-1999-0230 1 Cisco 1 Ios 2024-02-28 5.0 MEDIUM N/A
Buffer overflow in Cisco 7xx routers through the telnet service.
CVE-1999-0524 11 Apple, Cisco, Hp and 8 more 14 Mac Os X, Macos, Ios and 11 more 2024-02-28 2.1 LOW N/A
ICMP information such as (1) netmask and (2) timestamp is allowed from arbitrary hosts.
