- Elevation of privilege
- CWE-923 - Improper Restriction of Communication Channel to Intended Endpoints
Summary
In BlackBerry QNX Software Development Platform (SDP) 6.6.0, an elevation of privilege vulnerability in the default configuration of the QNX SDP with QNet enabled on networks comprising two or more QNet nodes could allow an attacker to access local and remote files or take ownership of files on other QNX nodes regardless of permissions by executing commands targeting arbitrary nodes from a secondary QNX 6.6.0 QNet node.

No mitigation information available for this CWE.
CAPEC-161: Infrastructure Manipulation
An attacker exploits characteristics of the infrastructure of a network entity in order to perpetrate attacks or information gathering on network objects or effect a change in the ordinary information flow between network objects. Most often, this involves manipulation of the routing of network messages so, instead of arriving at their proper destination, they are directed towards an entity of the attackers' choosing, usually a server controlled by the attacker. The victim is often unaware that their messages are not being processed correctly. For example, a targeted client may believe they are connecting to their own bank but, in fact, be connecting to a Pharming site controlled by the attacker which then collects the user's login information in order to hijack the actual bank account.
CAPEC-481: Contradictory Destinations in Traffic Routing Schemes
Adversaries can provide contradictory destinations when sending messages. Traffic is routed in networks using the domain names in various headers available at different levels of the OSI model. In a Content Delivery Network (CDN) multiple domains might be available, and if there are contradictory domain names provided it is possible to route traffic to an inappropriate destination. The technique, called Domain Fronting, involves using different domain names in the SNI field of the TLS header and the Host field of the HTTP header. An alternative technique, called Domainless Fronting, is similar, but the SNI field is left blank.
CAPEC-501: Android Activity Hijack
An adversary intercepts an implicit intent sent to launch a Android-based trusted activity and instead launches a counterfeit activity in its place. The malicious activity is then used to mimic the trusted activity's user interface and prompt the target to enter sensitive data as if they were interacting with the trusted activity.
CAPEC-697: DHCP Spoofing
An adversary masquerades as a legitimate Dynamic Host Configuration Protocol (DHCP) server by spoofing DHCP traffic, with the goal of redirecting network traffic or denying service to DHCP.
