CVE-1999-1466 1 Cisco 1 Ios 2026-04-16 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-1999-0230 1 Cisco 1 Ios 2026-04-16 N/A
Buffer overflow in Cisco 7xx routers through the telnet service.
CVE-2006-3101 1 Cisco 1 Secure Access Control Server 2026-04-16 N/A
Cross-site scripting (XSS) vulnerability in LogonProxy.cgi in Cisco Secure ACS for UNIX 2.3 allows remote attackers to inject arbitrary web script or HTML via the (1) error, (2) SSL, and (3) Ok parameters.
CVE-2003-1001 1 Cisco 9 Catalyst 6500, Catalyst 6500 Ws-svc-nam-1, Catalyst 6500 Ws-svc-nam-2 and 6 more 2026-04-16 N/A
Buffer overflow in the Cisco Firewall Services Module (FWSM) in Cisco Catalyst 6500 and 7600 series devices allows remote attackers to cause a denial of service (crash and reload) via HTTP auth requests for (1) TACACS+ or (2) RADIUS authentication.
CVE-2006-3595 1 Cisco 1 Router Web Setup 2026-04-16 N/A
The default configuration of IOS HTTP server in Cisco Router Web Setup (CRWS) before 3.3.0 build 31 does not require credentials, which allows remote attackers to access the server with arbitrary privilege levels, aka bug CSCsa78190.
CVE-2005-2241 1 Cisco 1 Call Manager 2026-04-16 N/A
Cisco CallManager (CCM) 3.2 and earlier, 3.3 before 3.3(5), 4.0 before 4.0(2a)SR2b, and 4.1 4.1 before 4.1(3)SR1 does not quickly time out Realtime Information Server Data Collection (RISDC) sockets, which results in a "resource leak" that allows remote attackers to cause a denial of service (memory and connection consumption) in RisDC.exe.
CVE-2006-4910 1 Cisco 2 Ids Sensor Software, Ips Sensor Software 2026-04-16 N/A
The web administration interface (mainApp) to Cisco IDS before 4.1(5c), and IPS 5.0 before 5.0(6p1) and 5.1 before 5.1(2) allows remote attackers to cause a denial of service (unresponsive device) via a crafted SSLv2 Client Hello packet.
CVE-2006-4650 1 Cisco 1 Ios 2026-04-16 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-2006-4774 1 Cisco 1 Ios 2026-04-16 N/A
The VLAN Trunking Protocol (VTP) feature in Cisco IOS 12.1(19) allows remote attackers to cause a denial of service by sending a VTP version 1 summary frame with a VTP version field value of 2.
CVE-2006-4430 1 Cisco 2 Network Admission Control, Network Admission Control Manager And Server System Software 2026-04-16 N/A
The Cisco Network Admission Control (NAC) 3.6.4.1 and earlier allows remote attackers to prevent installation of the Cisco Clean Access (CCA) Agent and bypass local and remote protection mechanisms by modifying (1) the HTTP User-Agent header or (2) the behavior of the TCP/IP stack. NOTE: the vendor has disputed the severity of this issue, stating that users cannot bypass authentication mechanisms.
CVE-2006-0764 1 Cisco 3 Anomaly Guard Module, Guard, Traffic Anomaly Detector Module 2026-04-16 N/A
The Authentication, Authorization, and Accounting (AAA) capability in versions 5.0(1) and 5.0(3) of the software used by multiple Cisco Anomaly Detection and Mitigation products, when running with an incomplete TACACS+ configuration without a "tacacs-server host" command, allows remote attackers to bypass authentication and gain privileges, aka Bug ID CSCsd21455.
CVE-1999-1582 1 Cisco 1 Pix Firewall 2026-04-16 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-2006-4194 1 Cisco 8 Pix Firewall 501, Pix Firewall 506, Pix Firewall 515 and 5 more 2026-04-16 N/A
Unspecified vulnerability in Cisco PIX 500 Series Security Appliances allows remote attackers to send arbitrary UDP packets to intranet devices via unspecified vectors involving Session Initiation Protocol (SIP) fixup commands, a different issue than CVE-2006-4032. NOTE: the vendor, after working with the researcher, has been unable to reproduce the issue
CVE-2006-4312 1 Cisco 9 Adaptive Security Appliance, Pix Firewall 501, Pix Firewall 506 and 6 more 2026-04-16 N/A
Cisco PIX 500 Series Security Appliances and ASA 5500 Series Adaptive Security Appliances, when running 7.0(x) up to 7.0(5) and 7.1(x) up to 7.1(2.4), and Firewall Services Module (FWSM) 3.1(x) up to 3.1(1.6), causes the EXEC password, local user passwords, and the enable password to be changed to a "non-random value" under certain circumstances, which causes administrators to be locked out and might allow attackers to gain access.
