The internal database in Cisco Wireless Control System (WCS) for Linux and Windows before 3.2(51) uses an undocumented, hard-coded username and password, which allows remote authenticated users to read, and possibly modify, sensitive configuration data (aka bugs CSCsd15955).
CVE-2001-1071 1 Cisco 2 Catos, Ios 2025-04-03 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-2005-2105 1 Cisco 1 Ios 2025-04-03 7.5 HIGH N/A
Cisco IOS 12.2T through 12.4 allows remote attackers to bypass Authentication, Authorization, and Accounting (AAA) RADIUS authentication, if the fallback method is set to none, via a long username.
CVE-2005-0196 1 Cisco 1 Ios 2025-04-03 5.0 MEDIUM N/A
Cisco IOS 12.0 through 12.3YL, with BGP enabled and running the bgp log-neighbor-changes command, allows remote attackers to cause a denial of service (device reload) via a malformed BGP packet.
CVE-1999-1216 1 Cisco 1 Router 2025-04-03 7.5 HIGH N/A
Cisco routers 9.17 and earlier allow remote attackers to bypass security restrictions via certain IP source routed packets that should normally be denied using the "no ip source-route" command.
CVE-1999-1466 1 Cisco 1 Ios 2025-04-03 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.
CVE-2000-0486 1 Cisco 2 Ios, Tacacs\+ 2025-04-03 5.0 MEDIUM N/A
Buffer overflow in Cisco TACACS+ tac_plus server allows remote attackers to cause a denial of service via a malformed packet with a long length field.
CVE-2002-0880 1 Cisco 2 Skinny Client Control Protocol Software, Voip Phone Cp-7940 2025-04-03 5.0 MEDIUM N/A
Cisco IP Phone (VoIP) models 7910, 7940, and 7960 allow remote attackers to cause a denial of service (crash) via malformed packets as demonstrated by (1) "jolt", (2) "jolt2", (3) "raped", (4) "hping2", (5) "bloop", (6) "bubonic", (7) "mutant", (8) "trash", and (9) "trash2."
CVE-2004-0308 1 Cisco 1 Optical Networking Systems Software 2025-04-03 10.0 HIGH N/A
Unknown vulnerability in Cisco ONS 15327 before 4.1(3), ONS 15454 before 4.6(1), ONS 15454 SD before 4.1(3), and Cisco ONS15600 before 1.3(0) allows a superuser whose account is locked out, disabled, or suspended to gain unauthorized access via a Telnet connection to the VxWorks shell.
CVE-1999-0889 1 Cisco 1 675 Router 2025-04-03 7.5 HIGH N/A
Cisco 675 routers running CBOS allow remote attackers to establish telnet sessions if an exec or superuser password has not been set.
CVE-2006-3288 1 Cisco 1 Wireless Control System 2025-04-03 5.0 MEDIUM N/A
Unspecified vulnerability in the TFTP server in Cisco Wireless Control System (WCS) for Linux and Windows before 3.2(51), when configured to use a directory path name that contains a space character, allows remote authenticated users to read and overwrite arbitrary files via unspecified vectors.
CVE-1999-0158 1 Cisco 1 Pix Firewall Software 2025-04-03 5.0 MEDIUM N/A
Cisco PIX firewall manager (PFM) on Windows NT allows attackers to connect to port 8080 on the PFM server and retrieve any file whose name and location is known.
CVE-2006-3286 1 Cisco 1 Wireless Control System 2025-04-03 7.5 HIGH N/A
The internal database in Cisco Wireless Control System (WCS) for Linux and Windows before 3.2(63) stores a hard-coded username and password in plaintext within unspecified files, which allows remote authenticated users to access the database (aka bug CSCsd15951).
CVE-2002-1556 1 Cisco 1 Optical Networking Systems Software 2025-04-03 5.0 MEDIUM N/A
Cisco ONS15454 and ONS15327 running ONS before 3.4 allows attackers to cause a denial of service (reset) via an HTTP request to the TCC, TCC+ or XTC, in which the request contains an invalid CORBA Interoperable Object Reference (IOR).
CVE-2006-4650 1 Cisco 1 Ios 2025-04-03 2.6 LOW N/A
Cisco IOS 12.0, 12.1, and 12.2, when GRE IP tunneling is used and the RFC2784 compliance fixes are missing, does not verify the offset field of a GRE packet during decapsulation, which leads to an integer overflow that references data from incorrect memory locations, which allows remote attackers to inject crafted packets into the routing queue, possibly bypassing intended router ACLs.
CVE-2006-2166 1 Cisco 2 Unity Express, Unity Express Software 2025-04-03 2.1 LOW N/A
Unspecified vulnerability in the HTTP management interface in Cisco Unity Express (CUE) 2.2(2) and earlier, when running on any CUE Advanced Integration Module (AIM) or Network Module (NM), allows remote authenticated attackers to reset the password for any user with an expired password.
CVE-2001-0863 1 Cisco 1 12000 Router 2025-04-03 5.0 MEDIUM N/A
Cisco 12000 with IOS 12.0 and line cards based on Engine 2 does not handle the "fragment" keyword in a compiled ACL (Turbo ACL) for packets that are sent to the router, which allows remote attackers to cause a denial of service via a flood of fragments.
CVE-2005-1058 1 Cisco 1 Ios 2025-04-03 7.5 HIGH N/A
Cisco IOS 12.2T, 12.3 and 12.3T, when processing an ISAKMP profile that specifies XAUTH authentication after Phase 1 negotiation, may not process certain attributes in the ISAKMP profile that specifies XAUTH, which allows remote attackers to bypass XAUTH and move to Phase 2 negotiations.

Cisco IOS 12.0 through 12.2, when IP routing is disabled, accepts false ICMP redirect messages, which allows remote attackers to cause a denial of service (network routing modification).
