CVE-2003-0983 1 Cisco 2 80-7111-01 For The Unity-svrx255-1a, 80-7112-01 For The Unity-svrx255-2a 2026-04-16 7.5 HIGH N/A
Cisco Unity on IBM servers is shipped with default settings that should have been disabled by the manufacturer, which allows local or remote attackers to conduct unauthorized activities via (1) a "bubba" local user account, (2) an open TCP port 34571, or (3) when a local DHCP server is unavailable, a DHCP server on the manufacturer's test network.
CVE-2003-1096 1 Cisco 1 Leap 2026-04-16 10.0 HIGH N/A
The Cisco LEAP challenge/response authentication mechanism uses passwords in a way that is susceptible to dictionary attacks, which makes it easier for remote attackers to gain privileges via brute force password guessing attacks.
CVE-2001-0444 1 Cisco 1 Cbos 2026-04-16 2.1 LOW N/A
Cisco CBOS 2.3.0.053 sends output of the "sh nat" (aka "show nat") command to the terminal of the next user who attempts to connect to the router via telnet, which could allow that user to obtain sensitive information.
CVE-2002-1107 1 Cisco 1 Vpn Client 2026-04-16 7.5 HIGH N/A
Cisco Virtual Private Network (VPN) Client software 2.x.x, and 3.x before 3.5.2B, does not generate sufficiently random numbers, which may make it vulnerable to certain attacks such as spoofing.
CVE-2003-0260 1 Cisco 6 Vpn 3000 Concentrator Series Software, Vpn 3002 Hardware Client, Vpn 3015 Concentrator and 3 more 2026-04-16 5.0 MEDIUM N/A
Cisco VPN 3000 series concentrators and Cisco VPN 3002 Hardware Client 2.x.x through 3.6.7A allow remote attackers to cause a denial of service (slowdown and possibly reload) via a flood of malformed ICMP packets.
CVE-2001-0741 1 Cisco 1 Hsrp 2026-04-16 2.1 LOW N/A
Cisco Hot Standby Routing Protocol (HSRP) allows local attackers to cause a denial of service by spoofing HSRP packets.
CVE-2002-0954 1 Cisco 1 Pix Firewall 2026-04-16 7.5 HIGH N/A
The encryption algorithms for enable and passwd commands on Cisco PIX Firewall can be executed quickly due to a limited number of rounds, which make it easier for an attacker to decrypt the passwords using brute force techniques.
CVE-1999-0453 1 Cisco 1 Router 2026-04-16 5.0 MEDIUM N/A
An attacker can identify a CISCO device by sending a SYN packet to port 1999, which is for the Cisco Discovery Protocol (CDP).
CVE-2002-2140 1 Cisco 1 Pix Firewall Software 2026-04-16 5.0 MEDIUM N/A
Buffer overflow in Cisco PIX Firewall 5.2.x to 5.2.8, 6.0.x to 6.0.3, 6.1.x to 6.1.3, and 6.2.x to 6.2.1 allows remote attackers to cause a denial of service via HTTP traffic authentication using (1) TACACS+ or (2) RADIUS.
CVE-2001-0753 1 Cisco 1 Cbos 2026-04-16 7.5 HIGH N/A
Cisco CBOS 2.3.8 and earlier stores the passwords for (1) exec and (2) enable in cleartext in the NVRAM and a configuration file, which could allow unauthorized users to obtain the passwords and gain privileges.
CVE-2002-2037 1 Cisco 5 Bams, Pgw 2200, Sc2200 and 2 more 2026-04-16 5.0 MEDIUM N/A
The Cisco Media Gateway Controller (MGC) in (1) SC2200 7.4 and earlier, (2) VSC3000 9.1 and earlier, (3) PGW 2200 9.1 and earlier, (4) Billing and Management Server (BAMS) and (5) Voice Services Provisioning Tool (VSPT) runs on default installations of Solaris 2.6 with unnecessary services and without the latest security patches, which allows attackers to exploit known vulnerabilities.
CVE-2002-0769 1 Cisco 1 Ata-186 2026-04-16 6.4 MEDIUM N/A
The web-based configuration interface for the Cisco ATA 186 Analog Telephone Adaptor allows remote attackers to bypass authentication via an HTTP POST request with a single byte, which allows the attackers to (1) obtain the password from the login screen, or (2) reconfigure the adaptor by modifying certain request parameters.
CVE-2005-3481 1 Cisco 1 Ios 2026-04-16 9.3 HIGH N/A
Cisco IOS 12.0 to 12.4 might allow remote attackers to execute arbitrary code via a heap-based buffer overflow in system timers. NOTE: this issue does not correspond to a specific vulnerability, rather a general weakness that only increases the feasibility of exploitation of any vulnerabilities that might exist. Such design-level weaknesses normally are not included in CVE, so perhaps this issue should be REJECTed.
CVE-2001-0566 1 Cisco 1 Catalyst 2900 2026-04-16 5.0 MEDIUM N/A
Cisco Catalyst 2900XL switch allows a remote attacker to create a denial of service via an empty UDP packet sent to port 161 (SNMP) when SNMP is disabled.
CVE-2001-0427 1 Cisco 6 Vpn 3000 Concentrator, Vpn 3005 Concentrator, Vpn 3015 Concentrator and 3 more 2026-04-16 7.1 HIGH N/A
Cisco VPN 3000 series concentrators before 2.5.2(F) allow remote attackers to cause a denial of service via a flood of invalid login requests to (1) the SSL service, or (2) the telnet service, which do not properly disconnect the user after several failed login attempts.
CVE-2005-0612 1 Cisco 7 Ipvc-3510-mcu, Ipvc-3520-gw-2b, Ipvc-3520-gw-2b2v and 4 more 2026-04-16 7.5 HIGH N/A
Cisco IP/VC Videoconferencing System 3510, 3520, 3525 and 3530 contain hard-coded default SNMP community strings, which allows remote attackers to gain access, cause a denial of service, and modify configuration.
CVE-1999-0159 1 Cisco 1 Ios 2026-04-16 5.0 MEDIUM 3.5 LOW
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-2002-0241 1 Cisco 1 Secure Access Control Server 2026-04-16 7.5 HIGH N/A
NDSAuth.DLL in Cisco Secure Authentication Control Server (ACS) 3.0.1 does not check the Expired or Disabled state of users in the Novell Directory Services (NDS), which could allow those users to authenticate to the server.
CVE-2000-1055 1 Cisco 1 Secure Access Control Server 2026-04-16 10.0 HIGH N/A
Buffer overflow in CiscoSecure ACS Server 2.4(2) and earlier allows remote attackers to cause a denial of service and possibly execute arbitrary commands via a large TACACS+ packet.
CVE-2002-0545 1 Cisco 2 Aironet Ap340, Aironet Ap350 2026-04-16 5.0 MEDIUM N/A
Cisco Aironet before 11.21 with Telnet enabled allows remote attackers to cause a denial of service (reboot) via a series of login attempts with invalid usernames and passwords.
