TITLE

Cisco Adaptive Security Appliances Service disruption on devices (DoS) Vulnerabilities

DESCRIPTION

Cisco Adaptive Security Appliances (ASA) 5500 series devices with software before 8.2(3) do not properly handle Online Certificate Status Protocol (OCSP) connection failures, which allows remote OCSP responders to cause a denial of service (TCP socket exhaustion) by rejecting connection attempts, aka Bug ID CSCsz36816. The problem is Bug ID CSCsz36816 It is a problem.remote OCSP Service disruption due to rejection of connection attempt by responder (DoS) There is a possibility of being put into a state. The Cisco Adaptive Security Appliance is an adaptive security appliance that provides modules for security and VPN services. Cisco ASA 5500 series appliances are prone to multiple remote vulnerabilities, including: Multiple security-bypass vulnerabilities Multiple denial-of-service vulnerabilities Attackers can exploit these issues to cause denial-of-service conditions or bypass certain security restrictions. ---------------------------------------------------------------------- Secure your corporate defenses and reduce complexity in handling vulnerability threats with the new Secunia Vulnerability Intelligence Manager (VIM).

Successful exploitation of this vulnerability requires valid credentials. 3) An error when handling unspecified IPSEC traffic can be exploited to cause a device to crash via a high volume of traffic. 4) An error in emWEB when handling filename requests can be exploited to crash the daemon by requesting a filename containing white space characters. 5) An error when handling packets during device startup can be exploited to bypass configured access restrictions. 7) An error in the WebVPN implementation when handling CIFS connections can be exploited to access a share via certain CIFS requests. Successful exploitation of this vulnerability requires valid credentials and CIFS file browsing to be disabled. 8) An error within SMTP inspection can be exploited to bypass the inspection via prepended space characters. 9) An error when handling LDAP connections can be exploited to exhaust memory resources via invalid authentication attempts. 10) An error within SIP inspection can be exploited to crash a device via a high volume of calls (greater than 600). 11) An error in the Mobile User Security (MUS) service when handling HTTP requests from a Web Security Appliance (WSA) can be exploited to bypass authentication via a HEAD request. 12) An error when handling unspecified multicast traffic can be exploited to crash a device. 13) An error when handling LAN-to-LAN (L2L) IPSEC sessions can be exploited to crash a device via a high volume of sessions (greater than 10000). The vulnerabilities are reported in versions prior to 8.2(4) and 8.3(2). SOLUTION: Update to versions 8.2(4) and 8.3(2). PROVIDED AND/OR DISCOVERED BY: Reported by the vendor.
