CVE-1999-1465 1 Cisco 1 Ios 2023-12-10 7.5 HIGH N/A
Vulnerability in Cisco IOS 11.1 through 11.3 with distributed fast switching (DFS) enabled allows remote attackers to bypass certain access control lists when the router switches traffic from a DFS-enabled input interface to an output interface with a logical subinterface, as described by Cisco bug CSCdk43862.
CVE-1999-0524 11 Apple, Cisco, Hp and 8 more 14 Mac Os X, Macos, Ios and 11 more 2023-12-10 2.1 LOW N/A
ICMP information such as (1) netmask and (2) timestamp is allowed from arbitrary hosts.
CVE-2001-0929 1 Cisco 1 Ios 2023-12-10 7.5 HIGH N/A
Cisco IOS Firewall Feature set, aka Context Based Access Control (CBAC) or Cisco Secure Integrated Software, for IOS 11.2P through 12.2T does not properly check the IP protocol type, which could allow remote attackers to bypass access control lists.
CVE-2002-1096 1 Cisco 2 Vpn 3000 Concentrator Series Software, Vpn 3002 Hardware Client 2023-12-10 7.5 HIGH N/A
Cisco VPN 3000 Concentrator 2.2.x, and 3.x before 3.5.1, allows restricted administrators to obtain user passwords that are stored in plaintext in HTML source code.
CVE-2002-1024 1 Cisco 4 Catos, Css11000 Content Services Switch, Ios and 1 more 2023-12-10 7.1 HIGH N/A
Cisco IOS 12.0 through 12.2, when supporting SSH, allows remote attackers to cause a denial of service (CPU consumption) via a large packet that was designed to exploit the SSH CRC32 attack detection overflow (CVE-2001-0144).
CVE-2002-1105 1 Cisco 1 Vpn Client 2023-12-10 4.6 MEDIUM N/A
Cisco Virtual Private Network (VPN) Client software 2.x.x, and 3.x before 3.5.1C, allows local users to use a utility program to obtain the group password.
CVE-2004-1434 1 Cisco 1 Optical Networking Systems Software 2023-12-10 5.0 MEDIUM N/A
Multiple versions of Cisco ONS 15327, ONS 15454, and ONS 15454 SDH, including 4.1(0) to 4.1(2), 4.5(x), 4.0(0) to 4.0(2), and earlier versions, allows remote attackers to cause a denial of service (control card reset) via malformed SNMP packets.
CVE-1999-1582 1 Cisco 1 Pix Firewall 2023-12-10 7.5 HIGH N/A
By design, the "established" command on the Cisco PIX firewall allows connections from one host to arbitrary ports of a target host if an alternative conduit has already been allowed, which can cause administrators to configure less restrictive access controls than intended if they do not understand this functionality.
CVE-2001-1183 1 Cisco 1 Ios 2023-12-10 5.0 MEDIUM N/A
PPTP implementation in Cisco IOS 12.1 and 12.2 allows remote attackers to cause a denial of service (crash) via a malformed packet.
CVE-1999-1175 1 Cisco 1 Ios 2023-12-10 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-2000-0368 1 Cisco 1 Ios 2023-12-10 2.1 LOW N/A
Classic Cisco IOS 9.1 and later allows attackers with access to the login prompt to obtain portions of the command history of previous users, which may allow the attacker to access sensitive data.
CVE-2003-1132 1 Cisco 2 Content Services Switch 11000, Content Services Switch 11500 2023-12-10 5.0 MEDIUM N/A
The DNS server for Cisco Content Service Switch (CSS) 11000 and 11500, when prompted for a nonexistent AAAA record, responds with response code 3 (NXDOMAIN or "Name Error") instead of response code 0 ("No Error"), which allows remote attackers to cause a denial of service (inaccessible domain) by forcing other DNS servers to send and cache a request for a AAAA record to the vulnerable server.
CVE-2002-0952 1 Cisco 1 Optical Networking Systems Software 2023-12-10 5.0 MEDIUM N/A
Cisco ONS15454 optical transport platform running ONS 3.1.0 to 3.2.0 allows remote attackers to cause a denial of service (reset) by sending IP packets with non-zero Type of Service (TOS) bits to the Timing Control Card (TCC) LAN interface.
CVE-2001-0057 1 Cisco 2 Broadband Operating System, Cisco 6xx Routers 2023-12-10 5.0 MEDIUM N/A
Cisco 600 routers running CBOS 2.4.1 and earlier allow remote attackers to cause a denial of service via a large ICMP echo (ping) packet.
CVE-2002-1554 1 Cisco 1 Optical Networking Systems Software 2023-12-10 4.6 MEDIUM N/A
Cisco ONS15454 and ONS15327 running ONS before 3.4 stores usernames and passwords in cleartext in the image database for the TCC, TCC+ or XTC, which could allow attackers to gain privileges by obtaining the passwords from the image database or a backup.
CVE-2001-1097 1 Cisco 1 Ios 2023-12-10 5.0 MEDIUM N/A
Cisco routers and switches running IOS 12.0 through 12.2.1 allows a remote attacker to cause a denial of service via a flood of UDP packets.
CVE-2001-0669 4 Cisco, Enterasys, Iss and 1 more 6 Catalyst 6000 Intrusion Detection System Module, Secure Intrusion Detection System, Dragon and 3 more 2023-12-10 7.5 HIGH N/A
