Cisco SN 5420 Storage Router 1.1(5) and earlier allows attackers to read configuration files without authorization.
CVE-2001-0754 1 Cisco 1 Cbos 2026-04-16 N/A
Cisco CBOS 2.3.8 and earlier allows remote attackers to cause a denial of service via a series of large ICMP ECHO REPLY (ping) packets, which cause it to enter ROMMON mode and stop forwarding packets.
CVE-2006-4982 1 Cisco 1 Network Access Control 2026-04-16 N/A
Cisco NAC maintains an exception list that does not record device properties other than MAC address, which allows physically proximate attackers to bypass control methods and join a local network by spoofing the MAC address of a different type of device, as demonstrated by using the MAC address of a disconnected printer.
CVE-2002-1558 1 Cisco 1 Optical Networking Systems Software 2026-04-16 N/A
Cisco ONS15454 and ONS15327 running ONS before 3.4 have an account for the VxWorks Operating System in the TCC, TCC+ and XTC that cannot be changed or disabled, which allows remote attackers to gain privileges by connecting to the account via Telnet.
CVE-2006-4909 1 Cisco 1 Guard Ddos Mitigation Appliance 2026-04-16 N/A
Cross-site scripting (XSS) vulnerability in Cisco Guard DDoS Mitigation Appliance before 5.1(6), when anti-spoofing is enabled, allows remote attackers to inject arbitrary web script or HTML via certain character sequences in a URL that are not properly handled when the appliance sends a meta-refresh.
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-2002-1557 1 Cisco 1 Optical Networking Systems Software 2026-04-16 N/A
Cisco ONS15454 and ONS15327 running ONS before 3.4 allows attackers to cause a denial of service (reset to TCC, TCC+, TCCi or XTC) via a malformed HTTP request that does not contain a leading / (slash) character.
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-2001-0753 1 Cisco 1 Cbos 2026-04-16 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-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.
CVE-2002-1556 1 Cisco 1 Optical Networking Systems Software 2026-04-16 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-1999-0416 1 Cisco 1 Cisco 7xx Routers 2026-04-16 N/A
Vulnerability in Cisco 7xx series routers allows a remote attacker to cause a system reload via a TCP connection to the router's TELNET port.
CVE-2001-0752 1 Cisco 1 Cbos 2026-04-16 N/A
Cisco CBOS 2.3.8 and earlier allows remote attackers to cause a denial of service via an ICMP ECHO REQUEST (ping) with the IP Record Route option set.
CVE-2006-4032 1 Cisco 1 Callmanager Express 2026-04-16 N/A
Unspecified vulnerability in Cisco IOS CallManager Express (CME) allows remote attackers to gain sensitive information (user names) from the Session Initiation Protocol (SIP) user directory via certain SIP messages, aka bug CSCse92417.
CVE-2000-0267 1 Cisco 1 Catos 2026-04-16 N/A
Cisco Catalyst 5.4.x allows a user to gain access to the "enable" mode without a password.
CVE-2006-3906 1 Cisco 21 Adaptive Security Appliance Software, Ios, Pix Asa Ids and 18 more 2026-04-16 N/A
Internet Key Exchange (IKE) version 1 protocol, as implemented on Cisco IOS, VPN 3000 Concentrators, and PIX firewalls, allows remote attackers to cause a denial of service (resource exhaustion) via a flood of IKE Phase-1 packets that exceed the session expiration rate. NOTE: it has been argued that this is due to a design weakness of the IKE version 1 protocol, in which case other vendors and implementations would also be affected.
CVE-2002-1555 1 Cisco 1 Optical Networking Systems Software 2026-04-16 N/A
Cisco ONS15454 and ONS15327 running ONS before 3.4 uses a "public" SNMP community string that cannot be changed, which allows remote attackers to obtain sensitive information.
