Cisco Adaptive Security Appliance (ASA) Software does not properly handle errors during the processing of DNS responses, which allows remote attackers to cause a denial of service (device reload) via a malformed response, aka Bug ID CSCuj28861.

The protocol-inspection feature on Cisco Adaptive Security Appliances (ASA) devices does not properly implement the idle timeout, which allows remote attackers to cause a denial of service (connection-table exhaustion) via crafted requests that use an inspected protocol, aka Bug ID CSCuh13899.

Cross-site scripting (XSS) vulnerability in the WebVPN portal login page on Cisco Adaptive Security Appliances (ASA) devices allows remote attackers to inject arbitrary web script or HTML via a crafted URL, aka Bug ID CSCug83080.

The Next-Generation Firewall (aka NGFW, formerly CX Context-Aware Security) module 9.x before 9.1.1.9 and 9.1.2.x before 9.1.2.12 for Cisco Adaptive Security Appliances (ASA) devices allows remote attackers to cause a denial of service (device reload or traffic-processing outage) via fragmented (1) IPv4 or (2) IPv6 traffic, aka Bug ID CSCue88387.

Race condition in the CIFS implementation in the rewriter module in the Clientless SSL VPN component on Cisco Adaptive Security Appliances (ASA) devices allows remote authenticated users to cause a denial of service (device reload) by accessing resources within multiple sessions, aka Bug ID CSCub58996.

The ISAKMP implementation on Cisco Adaptive Security Appliances (ASA) devices generates different responses for IKE aggressive-mode messages depending on whether invalid VPN groups are specified, which allows remote attackers to enumerate groups via a series of messages, aka Bug ID CSCue73708.

Cisco Adaptive Security Appliances (ASA) devices with software 9.0 before 9.0(1.2) allow remote attackers to cause a denial of service (device reload) via a crafted field in a DNS message, aka Bug ID CSCuc80080.

The authentication-proxy implementation on Cisco Adaptive Security Appliances (ASA) devices with software 7.x before 7.2(5.10), 8.0 before 8.0(5.31), 8.1 and 8.2 before 8.2(5.38), 8.3 before 8.3(2.37), 8.4 before 8.4(5.3), 8.5 and 8.6 before 8.6(1.10), 8.7 before 8.7(1.4), 9.0 before 9.0(1.1), and 9.1 before 9.1(1.2) allows remote attackers to cause a denial of service (device reload) via a crafted URL, aka Bug ID CSCud16590.

The NAT process on Cisco Adaptive Security Appliances (ASA) devices allows remote attackers to cause a denial of service (connections-table memory consumption) via crafted packets, aka Bug ID CSCue46386.

Cisco Adaptive Security Appliances (ASA) devices with firmware 8.4 do not properly validate unspecified input related to UNC share pathnames, which allows remote authenticated users to cause a denial of service (device crash) via unknown vectors, aka Bug ID CSCuc65775.

Cisco Adaptive Security Appliances (ASA) devices with firmware 8.x through 8.4(1) do not properly manage SSH sessions, which allows remote authenticated users to cause a denial of service (device crash) by establishing multiple sessions, aka Bug ID CSCtc59462.

Race condition on Cisco Adaptive Security Appliances (ASA) devices allows remote attackers to cause a denial of service (CPU consumption or device reload) by establishing multiple connections, leading to improper handling of hash lookups for secondary flows, aka Bug IDs CSCue31622 and CSCuc71272.

Multiple clientless SSL VPN products that run in web browsers, including Stonesoft StoneGate; Cisco ASA; SonicWALL E-Class SSL VPN and SonicWALL SSL VPN; SafeNet SecureWire Access Gateway; Juniper Networks Secure Access; Nortel CallPilot; Citrix Access Gateway; and other products, when running in configurations that do not restrict access to the same domain as the VPN, retrieve the content of remote URLs from one domain and rewrite them so they originate from the VPN's domain, which violates the same origin policy and allows remote attackers to conduct cross-site scripting attacks, read cookies that originated from other domains, access the Web VPN session to gain access to internal resources, perform key logging, and conduct other attacks. NOTE: it could be argued that this is a fundamental design problem in any clientless VPN solution, as opposed to a commonly-introduced error that can be fixed in separate implementations. Therefore a single CVE has been assigned for all products that have this design.

Cross-site scripting (XSS) vulnerability in +webvpn+/index.html in WebVPN on the Cisco Adaptive Security Appliances (ASA) 5520 with software 7.2(4)30 and earlier 7.2 versions including 7.2(2)22, and 8.0(4)28 and earlier 8.0 versions, when clientless mode is enabled, allows remote attackers to inject arbitrary web script or HTML via the Host HTTP header.

WebVPN on the Cisco Adaptive Security Appliances (ASA) device with software 8.0(4), 8.1.2, and 8.2.1 does not properly distinguish its own login screen from the login screens it produces for third-party (1) FTP and (2) CIFS servers, which makes it easier for remote attackers to trick a user into sending WebVPN credentials to an arbitrary server via a URL associated with that server, aka Bug ID CSCsy80709.

WebVPN on the Cisco Adaptive Security Appliances (ASA) device with software 8.0(4), 8.1.2, and 8.2.1 allows remote attackers to bypass certain protection mechanisms involving URL rewriting and HTML rewriting, and conduct cross-site scripting (XSS) attacks, by modifying the first hex-encoded character in a /+CSCO+ URI, aka Bug ID CSCsy80705.

Eval injection vulnerability in the csco_wrap_js function in /+CSCOL+/cte.js in WebVPN on the Cisco Adaptive Security Appliances (ASA) device with software 8.0(4), 8.1.2, and 8.2.1 allows remote attackers to bypass a DOM wrapper and conduct cross-site scripting (XSS) attacks by setting CSCO_WebVPN['process'] to the name of a crafted function, aka Bug ID CSCsy80694.

Cisco Adaptive Security Appliance (ASA) and Cisco PIX security appliance 8.0.x before 8.0(3)9 and 8.1.x before 8.1(1)1 allows remote attackers to cause a denial of service (device reload) via a crafted Transport Layer Security (TLS) packet to the device interface.

Cisco PIX and ASA appliances with 7.1 and 7.2 software, when configured for TLS sessions to the device, allow remote attackers to cause a denial of service (device reload) via a crafted TLS packet, aka CSCsg43276 and CSCsh97120.

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.
