CVE-1999-0775 1 Cisco 1 Ios 2025-04-03 10.0 HIGH N/A
Cisco Gigabit Switch routers running IOS allow remote attackers to forward unauthorized packets due to improper handling of the "established" keyword in an access list.
CVE-2006-0367 1 Cisco 1 Call Manager 2025-04-03 6.5 MEDIUM N/A
Unspecified vulnerability in Cisco CallManager 3.2 and earlier, 3.3 before 3.3(5)SR1, 4.0 before 4.0(2a)SR2c, and 4.1 before 4.1(3)SR2 allows remote authenticated users with read-only administrative privileges to obtain full administrative privileges via a "crafted URL on the CCMAdmin web page."
CVE-1999-1582 1 Cisco 1 Pix Firewall 2025-04-03 7.5 HIGH 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-2001-1064 1 Cisco 1 Cbos 2025-04-03 5.0 MEDIUM N/A
Cisco 600 series routers running CBOS 2.0.1 through 2.4.2ap allows remote attackers to cause a denial of service via multiple connections to the router on the (1) HTTP or (2) telnet service, which causes the router to become unresponsive and stop forwarding packets.
CVE-2001-0754 1 Cisco 1 Cbos 2025-04-03 5.0 MEDIUM 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-2001-0444 1 Cisco 1 Cbos 2025-04-03 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-2001-0783 1 Cisco 1 Tftp Server 2025-04-03 5.0 MEDIUM N/A
Cisco TFTP server 1.1 allows remote attackers to read arbitrary files via a ..(dot dot) attack in the GET command.
CVE-2006-3226 1 Cisco 1 Secure Access Control Server 2025-04-03 7.5 HIGH N/A
Cisco Secure Access Control Server (ACS) 4.x for Windows uses the client's IP address and the server's port number to grant access to an HTTP server port for an administration session, which allows remote attackers to bypass authentication via various methods, aka "ACS Weak Session Management Vulnerability."
CVE-2001-1038 1 Cisco 1 Sn 5420 Storage Router Firmware 2025-04-03 5.0 MEDIUM N/A
Cisco SN 5420 Storage Router 1.1(3) and earlier allows remote attackers to cause a denial of service (reboot) via a series of connections to TCP port 8023.
CVE-2005-1942 1 Cisco 1 Catalyst 2025-04-03 7.5 HIGH N/A
Cisco switches that support 802.1x security allow remote attackers to bypass port security and gain access to the VLAN via spoofed Cisco Discovery Protocol (CDP) messages.
CVE-2006-1672 1 Cisco 5 Ons 15310-cl Series, Ons 15454 Mspp, Ons 15600 and 2 more 2025-04-03 7.5 HIGH N/A
The installation of Cisco Transport Controller (CTC) for Cisco Optical Networking System (ONS) 15000 series nodes adds a Java policy file entry with a wildcard that grants the java.security.AllPermission permission to any http URL containing "fs/LAUNCHER.jar", which allows remote attackers to execute arbitrary code on a CTC workstation, aka bug ID CSCea25049.
CVE-2004-0714 1 Cisco 3 Ios, Ons 15454e Optical Transport Platform, Optical Networking Systems Software 2025-04-03 5.0 MEDIUM N/A
Cisco Internetwork Operating System (IOS) 12.0S through 12.3T attempts to process SNMP solicited operations on improper ports (UDP 162 and a randomly chosen UDP port), which allows remote attackers to cause a denial of service (device reload and memory corruption).
CVE-2002-2052 1 Cisco 1 Ios 2025-04-03 5.0 MEDIUM N/A
Cisco 2611 router running IOS 12.1(6.5), possibly an interim release, allows remote attackers to cause a denial of service via port scans such as (1) scanning all ports on a single host and (2) scanning a network of hosts for a single open port through the router. NOTE: the vendor could not reproduce this issue, saying that the original reporter was using an interim release of the software.
CVE-2004-0551 1 Cisco 24 Catalyst 2901, Catalyst 2902, Catalyst 2926 and 21 more 2025-04-03 5.0 MEDIUM N/A
Cisco CatOS 5.x before 5.5(20) through 8.x before 8.2(2) and 8.3(2)GLX, as used in Catalyst switches, allows remote attackers to cause a denial of service (system crash and reload) by sending invalid packets instead of the final ACK portion of the three-way handshake to the (1) Telnet, (2) HTTP, or (3) SSH services, aka "TCP-ACK DoS attack."
CVE-1999-1465 1 Cisco 1 Ios 2025-04-03 7.5 HIGH N/A
Vulnerability in Cisco IOS 11.1 through 11.3 with distributed fast switching (DFS) enabled allows remote attackers to bypass certain access control lists when the router switches traffic from a DFS-enabled input interface to an output interface with a logical subinterface, as described by Cisco bug CSCdk43862.
CVE-2002-2239 1 Cisco 3 Catalyst 6500, Catalyst 7600, Ios 2025-04-03 7.8 HIGH N/A
The Cisco Optical Service Module (OSM) for the Catalyst 6500 and 7600 series running Cisco IOS 12.1(8)E through 12.1(13.4)E allows remote attackers to cause a denial of service (hang) via a malformed packet.
CVE-2001-0622 1 Cisco 1 Content Services Switch 11000 2025-04-03 7.5 HIGH N/A
The web management service on Cisco Content Service series 11000 switches (CSS) before WebNS 4.01B29s or WebNS 4.10B17s allows a remote attacker to gain additional privileges by directly requesting the web management URL instead of navigating through the interface.
CVE-2000-0955 1 Cisco 1 Virtual Central Office 4000 2025-04-03 7.5 HIGH N/A
Cisco Virtual Central Office 4000 (VCO/4K) uses weak encryption to store usernames and passwords in the SNMP MIB, which allows an attacker who knows the community name to crack the password and gain privileges.
