Summary

Adobe Thor versions 3.9.5.353 and earlier have a vulnerability in the directory search path used to find resources, related to Creative Cloud desktop applications.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Leveraging/Manipulating Configuration File Search Paths
    This attack loads a malicious resource into a program's standard path used to bootstrap and/or provide contextual information for a program like a path variable or classpath. J2EE applications and other component based applications that are built from multiple binaries can have very long list of dependencies to execute. If one of these libraries and/or references is controllable by the attacker then application controls can be circumvented by the attacker. A standard UNIX path looks similar to this If the attacker modifies the path variable to point to a locale that includes malicious resources then the user unwittingly can execute commands on the attackers' behalf: This is a form of usurping control of the program and the attack can be done on the classpath, database resources, or any other resources built from compound parts. At runtime detection and blocking of this attack is nearly impossible, because the configuration allows execution.

descriptionThe version of Adobe Creative Cloud Desktop installed on the remote Windows host is prior to 4.0.0.185. It is, therefore, affected by the following vulnerabilities : - An unspecified flaw exists in the installation process due to improper usage of resource permissions that allows an unauthenticated, remote attacker to have an unspecified impact. (CVE-2017-3006) - An information disclosure vulnerability exists due to using insecure directory search paths when locating resources. An unauthenticated, remote attacker can exploit this to disclose sensitive information, which potentially could be used to facilitate further remote code execution attacks. (CVE-2017-3007) Note that Nessus has not tested for these issues but has instead relied only on the application
