Multiple versions of Cisco ONS 15327, ONS 15454, and ONS 15454 SDH, including 4.6(0) and 4.6(1), 4.5(x), 4.1(0) to 4.1(3), 4.0(0) to 4.0(2), and earlier versions, allows remote attackers to cause a denial of service (control card reset) via a large number of TCP connections with an invalid response instead of the final ACK (TCP-ACK).
CVE-2004-1112 2 Cisco, Okena 2 Security Agent, Stormwatch 2026-04-16 N/A
The buffer overflow trigger in Cisco Security Agent (CSA) before 4.0.3 build 728 waits five minutes for a user response before terminating the process, which could allow remote attackers to bypass the buffer overflow protection by sending additional buffer overflow attacks within the five minute timeout period.
CVE-2004-0079 23 4d, Apple, Avaya and 20 more 67 Webstar, Mac Os X, Mac Os X Server and 64 more 2026-04-16 7.5 High
The do_change_cipher_spec function in OpenSSL 0.9.6c to 0.9.6k, and 0.9.7a to 0.9.7c, allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that triggers a null dereference.
CVE-2004-0244 1 Cisco 1 Ios 2026-04-16 N/A
Cisco 6000, 6500, and 7600 series systems with Multilayer Switch Feature Card 2 (MSFC2) and a FlexWAN or OSM module allow local users to cause a denial of service (hang or reset) by sending a layer 2 frame packet that encapsulates a layer 3 packet, but has inconsistent length values with that packet.
CVE-2003-1096 1 Cisco 1 Leap 2026-04-16 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-2003-0511 1 Cisco 1 Ios 2026-04-16 N/A
The web server for Cisco Aironet AP1x00 Series Wireless devices running certain versions of IOS 12.2 allow remote attackers to cause a denial of service (reload) via a malformed URL.
CVE-2003-0259 1 Cisco 6 Vpn 3000 Concentrator Series Software, Vpn 3002 Hardware Client, Vpn 3015 Concentrator and 3 more 2026-04-16 N/A
Cisco VPN 3000 series concentrators and Cisco VPN 3002 Hardware Client 2.x.x through 3.6.7 allows remote attackers to cause a denial of service (reload) via a malformed SSH initialization packet.
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-2002-1095 1 Cisco 3 Secure Access Control Server, Vpn 3000 Concentrator Series Software, Vpn 3002 Hardware Client 2026-04-16 N/A
Cisco VPN 3000 Concentrator before 2.5.2(F), with encryption enabled, allows remote attackers to cause a denial of service (reload) via a Windows-based PPTP client with the "No Encryption" option set.
CVE-2002-0769 1 Cisco 1 Ata-186 2026-04-16 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-2002-0241 1 Cisco 1 Secure Access Control Server 2026-04-16 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-2000-1022 1 Cisco 1 Pix Firewall Software 2026-04-16 N/A
The mailguard feature in Cisco Secure PIX Firewall 5.2(2) and earlier does not properly restrict access to SMTP commands, which allows remote attackers to execute restricted commands by sending a DATA command before sending the restricted commands.
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-1999-0998 1 Cisco 1 Cache Engine 2026-04-16 N/A
Cisco Cache Engine allows an attacker to replace content in the cache.
CVE-1999-0063 1 Cisco 1 Ios 2026-04-16 N/A
