CVE-2002-0813 1 Cisco 1 Ios 2025-04-03 7.1 HIGH N/A
Heap-based buffer overflow in the TFTP server capability in Cisco IOS 11.1, 11.2, and 11.3 allows remote attackers to cause a denial of service (reset) or modify configuration via a long filename.
CVE-2000-0345 1 Cisco 7 Ios, Router 2500, Router 2600 and 4 more 2025-04-03 2.1 LOW N/A
The on-line help system options in Cisco routers allows non-privileged users without "enabled" access to obtain sensitive information via the show command.
CVE-2004-0244 1 Cisco 1 Ios 2025-04-03 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-1999-1306 1 Cisco 1 Ios 2025-04-03 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-2002-1357 7 Cisco, Fissh, Intersoft and 4 more 7 Ios, Ssh Client, Securenetterm and 4 more 2025-04-03 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-2005-4258 1 Cisco 71 Catalyst, Catalyst 1200 Series, Catalyst 1900 Series and 68 more 2025-04-03 7.8 HIGH N/A
Unspecified Cisco Catalyst Switches allow remote attackers to cause a denial of service (device crash) via an IP packet with the same source and destination IPs and ports, and with the SYN flag set (aka LanD). NOTE: the provenance of this issue is unknown; the details are obtained solely from the BID.
CVE-1999-0159 1 Cisco 1 Ios 2025-04-03 5.0 MEDIUM N/A
Attackers can crash a Cisco IOS router or device, provided they can get to an interactive prompt (such as a login). This applies to some IOS 9.x, 10.x, and 11.x releases.
CVE-1999-0445 1 Cisco 1 Ios 2025-04-03 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-2006-0485 1 Cisco 1 Ios 2025-04-03 4.6 MEDIUM N/A
The TCL shell in Cisco IOS 12.2(14)S before 12.2(14)S16, 12.2(18)S before 12.2(18)S11, and certain other releases before 25 January 2006 does not perform Authentication, Authorization, and Accounting (AAA) command authorization checks, which may allow local users to execute IOS EXEC commands that were prohibited via the AAA configuration, aka Bug ID CSCeh73049.
CVE-2005-3921 1 Cisco 1 Ios 2025-04-03 2.6 LOW N/A
Cross-site scripting (XSS) vulnerability in Cisco IOS Web Server for IOS 12.0(2a) allows remote attackers to inject arbitrary web script or HTML by (1) packets containing HTML that an administrator views via an HTTP interface to the contents of memory buffers, as demonstrated by the URI /level/15/exec/-/buffers/assigned/dump; or (2) sending the router Cisco Discovery Protocol (CDP) packets with HTML payload that an administrator views via the CDP status pages. NOTE: these vectors were originally reported as being associated with the dump and packet options in /level/15/exec/-/show/buffers.
CVE-2004-0112 24 4d, Apple, Avaya and 21 more 65 Webstar, Mac Os X, Mac Os X Server and 62 more 2025-04-03 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-1999-0157 1 Cisco 2 Ios, Pix Firewall Software 2025-04-03 5.0 MEDIUM N/A
Cisco PIX firewall and CBAC IP fragmentation attack results in a denial of service.
CVE-2006-4950 1 Cisco 1 Ios 2025-04-03 10.0 HIGH N/A
Cisco IOS 12.2 through 12.4 before 20060920, as used by Cisco IAD2430, IAD2431, and IAD2432 Integrated Access Devices, the VG224 Analog Phone Gateway, and the MWR 1900 and 1941 Mobile Wireless Edge Routers, is incorrectly identified as supporting DOCSIS, which allows remote attackers to gain read-write access via a hard-coded cable-docsis community string and read or modify arbitrary SNMP variables.
CVE-1999-0162 1 Cisco 1 Ios 2025-04-03 5.0 MEDIUM N/A
The "established" keyword in some Cisco IOS software allowed an attacker to bypass filtering.
CVE-2006-4775 1 Cisco 2 Catos, Ios 2025-04-03 7.8 HIGH N/A
The VLAN Trunking Protocol (VTP) feature in Cisco IOS 12.1(19) and CatOS allows remote attackers to cause a denial of service by sending a VTP update with a revision value of 0x7FFFFFFF, which is incremented to 0x80000000 and is interpreted as a negative number in a signed context.
CVE-2005-0195 1 Cisco 1 Ios 2025-04-03 5.0 MEDIUM N/A
Cisco IOS 12.0S through 12.3YH allows remote attackers to cause a denial of service (device restart) via a crafted IPv6 packet.
