Beschreibung:Summary:
A vulnerability in XML parser code of Cisco Adaptive Security Appliance
Software could allow an authenticated, remote attacker to cause system instability or a reload of the
affected system.

The vulnerability is due to insufficient hardening of the XML parser configuration. An attacker could exploit
this vulnerability in multiple ways by utilizing a malicious file. An attacker with administrative privileges
could exploit this by uploading a malicious XML file on the system and trigger the XML code to parse the
malicious file. Additionally, an attacker with Clienteles SSL VPN access could exploit this vulnerability
by sending a crafted XML file. An exploit would allow the attacker to crash the XML parser process, which
could cause system instability, memory exhaustion, and in some cases lead to a reload of the affected system.

Cisco has released software updates that address this vulnerability. Workarounds that address this vulnerability
are not available.
