Description

Some vulnerabilities have been reported in Cisco ASA and PIX appliances, which can be exploited by malicious people to disclose sensitive information, and by malicious users and malicious people to cause a DoS (Denial of Service).

1) An unspecified error when processing SIP packets can be exploited to reload an affected device that has SIP inspection enabled.

The vulnerability is reported in Cisco PIX and ASA software versions prior to 7.0(7)16, 7.1(2)71, 7.2(4)7, 8.0(3)20, and 8.1(1)8.

2) An unspecified error when Cisco PIX and Cisco ASA devices are configured to terminate client based VPN connections can be exploited to reload the device.

Successful exploitation requires valid user credentials.

The vulnerability is reported in Cisco PIX and Cisco ASA software versions prior to 7.2(4)2, 8.0(3)14, and 8.1(1)4. Devices that run software versions 7.0 and 7.1 are reportedly not affected by this vulnerability.

3) A memory leak in Cisco ASA devices that are configured to terminate clientless VPN connections can be exploited to reload the device via specially crafted SSL or HTTP packets.

The vulnerability is reported in Cisco ASA software version prior to 7.2(4)2, 8.0(3)14, or 8.1(1)4. Cisco ASA devices that run software versions 7.0 and 7.1 are not affected by this vulnerability.

4) An unspecified error within the URI processing in Cisco ASA devices that terminate clientless remote access VPN connections can be exploited to reload the device.

The vulnerability is reported in Cisco ASA software versions prior to 8.0(3)15, and 8.1(1)5. Cisco ASA devices that run software versions 7.0, 7.1, or 7.2 are not affected by this vulnerability.

5) An unspecified error in Cisco ASA devices configured to terminate clientless VPN connections can be exploited to disclose potentially sensitive information such as usernames and passwords.

Successful exploitation requires that a user is tricked into e.g. visiting a malicious web server or reply to an email.

The vulnerability is reported in Cisco ASA devices running software versions 8.0 or 8.1 with clientless VPNs enabled. Cisco ASA devices that run software versions 7.0, 7.1, or 7.2 are not affected.
