Multiple cross-site scripting (XSS) vulnerabilities in the HTTP server in Cisco IOS 12.4(23) allow remote attackers to inject arbitrary web script or HTML via the PATH_INFO to the default URI under (1) level/15/exec/-/ or (2) exec/, a different vulnerability than CVE-2008-3821.
CVE-2008-3802 1 Cisco 1 Ios 2025-04-09 7.1 HIGH N/A
Unspecified vulnerability in the Session Initiation Protocol (SIP) implementation in Cisco IOS 12.2 through 12.4, when VoIP is configured, allows remote attackers to cause a denial of service (device reload) via unspecified valid SIP messages, aka Cisco bug ID CSCsk42759, a different vulnerability than CVE-2008-3800 and CVE-2008-3801.
CVE-2009-0630 1 Cisco 1 Ios 2025-04-09 7.1 HIGH N/A
The (1) Cisco Unified Communications Manager Express; (2) SIP Gateway Signaling Support Over Transport Layer Security (TLS) Transport; (3) Secure Signaling and Media Encryption; (4) Blocks Extensible Exchange Protocol (BEEP); (5) Network Admission Control HTTP Authentication Proxy; (6) Per-user URL Redirect for EAPoUDP, Dot1x, and MAC Authentication Bypass; (7) Distributed Director with HTTP Redirects; and (8) TCP DNS features in Cisco IOS 12.0 through 12.4 do not properly handle IP sockets, which allows remote attackers to cause a denial of service (outage or resource consumption) via a series of crafted TCP packets.
CVE-2009-0637 1 Cisco 2 Ios, Ios Xr 2025-04-09 7.1 HIGH N/A
The SCP server in Cisco IOS 12.2 through 12.4, when Role-Based CLI Access is enabled, does not enforce the CLI view configuration for file transfers, which allows remote authenticated users with an attached CLI view to (1) read or (2) overwrite arbitrary files via an SCP command.
CVE-2009-0471 1 Cisco 1 Ios 2025-04-09 6.8 MEDIUM N/A
Cross-site request forgery (CSRF) vulnerability in the HTTP server in Cisco IOS 12.4(23) allows remote attackers to execute arbitrary commands, as demonstrated by executing the hostname command with a level/15/configure/-/hostname request.
CVE-2002-2053 1 Cisco 1 Ios 2025-04-03 5.0 MEDIUM N/A
The design of the Hot Standby Routing Protocol (HSRP), as implemented on Cisco IOS 12.1, when using IRPAS, allows remote attackers to cause a denial of service (CPU consumption) via a router with the same IP address as the interface on which HSRP is running, which causes a loop.
CVE-2005-4258 1 Cisco 71 Catalyst, Catalyst 1200 Series, Catalyst 1900 Series and 68 more 2025-04-03 7.8 HIGH N/A
Unspecified Cisco Catalyst Switches allow remote attackers to cause a denial of service (device crash) via an IP packet with the same source and destination IPs and ports, and with the SYN flag set (aka LanD). NOTE: the provenance of this issue is unknown; the details are obtained solely from the BID.
CVE-1999-1175 1 Cisco 1 Ios 2025-04-03 7.5 HIGH N/A
Web Cache Control Protocol (WCCP) in Cisco Cache Engine for Cisco IOS 11.2 and earlier does not use authentication, which allows remote attackers to redirect HTTP traffic to arbitrary hosts via WCCP packets to UDP port 2048.
CVE-2000-0268 1 Cisco 12 3660 Router, 7100 Router, 7200 Router and 9 more 2025-04-03 5.0 MEDIUM N/A
Cisco IOS 11.x and 12.x allows remote attackers to cause a denial of service by sending the ENVIRON option to the Telnet daemon before it is ready to accept it, which causes the system to reboot.
CVE-2004-0710 1 Cisco 1 Ios 2025-04-03 5.0 MEDIUM N/A
IP Security VPN Services Module (VPNSM) in Cisco Catalyst 6500 Series Switch and the Cisco 7600 Series Internet Routers running IOS before 12.2(17b)SXA, before 12.2(17d)SXB, or before 12.2(14)SY03 could allow remote attackers to cause a denial of service (device crash and reload) via a malformed Internet Key Exchange (IKE) packet.
CVE-1999-0161 1 Cisco 1 Ios 2025-04-03 7.5 HIGH N/A
In Cisco IOS 10.3, with the tacacs-ds or tacacs keyword, an extended IP access control list could bypass filtering.
CVE-2005-0195 1 Cisco 1 Ios 2025-04-03 5.0 MEDIUM N/A
Cisco IOS 12.0S through 12.3YH allows remote attackers to cause a denial of service (device restart) via a crafted IPv6 packet.
CVE-2000-0700 1 Cisco 4 Gigabit Switch Router 12008, Gigabit Switch Router 12012, Gigabit Switch Router 12016 and 1 more 2025-04-03 5.0 MEDIUM N/A
Cisco Gigabit Switch Routers (GSR) with Fast Ethernet / Gigabit Ethernet cards, from IOS versions 11.2(15)GS1A up to 11.2(19)GS0.2 and some versions of 12.0, do not properly handle line card failures, which allows remote attackers to bypass ACLs or force the interface to stop forwarding packets.
CVE-2005-4826 1 Cisco 1 Ios 2025-04-03 6.1 MEDIUM N/A
Unspecified vulnerability in the VLAN Trunking Protocol (VTP) feature in Cisco IOS 12.1(22)EA3 on Catalyst 2950T switches allows remote attackers to cause a denial of service (device reboot) via a crafted Subset-Advert message packet, a different issue than CVE-2006-4774, CVE-2006-4775, and CVE-2006-4776.
CVE-2004-1776 1 Cisco 1 Ios 2025-04-03 7.5 HIGH N/A
Cisco IOS 12.1(3) and 12.1(3)T allows remote attackers to read and modify device configuration data via the cable-docsis read-write community string used by the Data Over Cable Service Interface Specification (DOCSIS) standard.
CVE-2002-2208 2 Cisco, Extended Interior Gateway Routing Protocol 2 Ios, Extended Interior Gateway Routing Protocol 2025-04-03 7.8 HIGH N/A
Extended Interior Gateway Routing Protocol (EIGRP), as implemented in Cisco IOS 11.3 through 12.2 and other products, allows remote attackers to cause a denial of service (flood) by sending a large number of spoofed EIGRP neighbor announcements, which results in an ARP storm on the local network.
