CVE-2005-3482 1 Cisco 3 Aironet Ap1131, Aironet Ap1200, Aironet Ap1240 2026-04-16 N/A
Cisco 1200, 1131, and 1240 series Access Points, when operating in Lightweight Access Point Protocol (LWAPP) mode and controlled by 2000 and 4400 series Airespace WLAN controllers running 3.1.59.24, allow remote attackers to send unencrypted traffic to a secure network using frames with the MAC address of an authenticated end host.
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-2006-1928 1 Cisco 1 Ios Xr 2026-04-16 N/A
Cisco IOS XR, when configured for Multi Protocol Label Switching (MPLS) and running on Cisco CRS-1 routers, allows remote attackers to cause a denial of service (Modular Services Cards (MSC) crash or "MPLS packet handling problems") via certain MPLS packets, as identified by Cisco bug IDs (1) CSCsd15970 and (2) CSCsd55531.
CVE-2006-1960 1 Cisco 1 Wireless Lan Solution Engine 2026-04-16 N/A
Cross-site scripting (XSS) vulnerability in the appliance web user interface in Cisco CiscoWorks Wireless LAN Solution Engine (WLSE) and WLSE Express before 2.13 allows remote attackers to inject arbitrary web script or HTML, possibly via the displayMsg parameter to archiveApplyDisplay.jsp, aka bug ID CSCsc01095.
