Identity Spoofing refers to the action of assuming (i.e., taking on) the identity of some other entity (human or non-human) and then using that identity to accomplish a goal. This attack does not rely on prior sessions established by successfully authenticating users, as relied upon for the 'Exploitation of Session Variables, Resource IDs and other Trusted Credentials' attack patterns. This attack differs from Authentication Bypass attacks in that Authentication Abuse allows the attacker to be certified as a valid user through illegitimate means, while Authentication Bypass allows the user to access protected material without ever being certified as an authenticated user. This attack may exploit assumptions made by the target's authentication procedures, such as assumptions regarding trust relationships or assumptions regarding the generation of secret values. In such an attack an authentication mechanism is functioning but a carefully controlled sequence of events causes the mechanism to grant access to the attacker. There is not typically an authentication on the client side, beyond what is passed in the request itself so once this is compromised, then this is generally sufficient to compromise the service's authentication scheme.ДЄn attacker obtains unauthorized access to an application, service or device either through knowledge of the inherent weaknesses of an authentication mechanism, or by exploiting a flaw in the authentication scheme's implementation. Once the attacker gathers these credentials, they can submit requests to the web service provider just as authorized user do.

The attacker can utilize a sniffer such as Wireshark to snapshot the credentials, such as username and password that are passed in the clear once SSL is terminated. Once the SSL is terminated the HTTP request is in the clear (unless developers have hashed or encrypted the values, but this is rare). In large data centers, SSL is typically terminated at the edge of the network - at the firewall, load balancer, or router. Unfortunately from a security standpoint, there frequently is no interoperable identity security mechanism deployed, so Rest developers often fall back to SSL to deliver security. These Rest style web services are deployed on existing infrastructure such as Apache and IIS web servers with no SOAP stack required. An example of this is a Rest application that uses HTTP Get methods and receives a HTTP response with an XML document.

Rest applications premise is that they leverage existing infrastructure to deliver web services functionality. This attack utilizes a REST(REpresentational State Transfer)-style applications' trust in the system resources and environment to obtain sensitive data once SSL is terminated. Utilizing REST's Trust in the System Resource to Obtain Sensitive Data.These attacks also differ from interception attacks since they may forward the sender's original unmodified data, after copying it, instead of keeping it for themselves. MITM attacks differ from sniffing attacks since they often modify the communications prior to delivering it to the intended recipient. The potential for Man-in-the-Middle attacks yields an implicit lack of trust in communication or identify between two components. This interposition is transparent leaving the two compromised components unaware of the potential corruption or leakage of their communications. Whenever one component attempts to communicate with the other (data flow, authentication challenges, etc.), the data first goes to the attacker, who has the opportunity to observe or alter it, and it is then passed on to the other component as if it was never observed. The attacker places himself in the communication channel between the two components. This type of attack targets the communication between two components (typically client and server). This issue impacts: PAN-OS 8.1 versions earlier than PAN-OS 8.1.17 PAN-OS 9.0 versions earlier than PAN-OS 9.0.11 PAN-OS 9.1 versions earlier than PAN-OS 9.1.5 PAN-OS 10.0 versions earlier than PAN-OS 10.0.1.

Impacted features that use SSL VPN with client certificate verification are: GlobalProtect Gateway, GlobalProtect Portal, GlobalProtect Clientless VPN In configurations where client certificate verification is used in conjunction with other authentication methods, the protections added by the certificate check are ignored as a result of this issue. A remote attacker can successfully authenticate as any user and gain access to restricted VPN network resources when the gateway or portal is configured to rely entirely on certificate-based authentication.

#GLOBALPROTECT CLIENTLESS VPN SOFTWARE#

An authentication bypass vulnerability exists in the GlobalProtect SSL VPN component of Palo Alto Networks PAN-OS software that allows an attacker to bypass all client certificate checks with an invalid certificate.
