CVE-2019-3726
|
Summary |
An Uncontrolled Search Path Vulnerability is applicable to the following: Dell Update Package (DUP) Framework file versions prior to 19.1.0.413, and Framework file versions prior to 103.4.6.69 used in Dell EMC Servers. Dell Update Package (DUP) Framework file versions prior to 3.8.3.67 used in Dell Client Platforms. The vulnerability is limited to the DUP framework during the time window when a DUP is being executed by an administrator. During this time window, a locally authenticated low privilege malicious user potentially could exploit this vulnerability by tricking an administrator into running a trusted binary, causing it to load a malicious DLL and allowing the attacker to execute arbitrary code on the victim system. The vulnerability does not affect the actual binary payload that the DUP delivers. |

Leveraging/Manipulating Configuration File Search Paths
This pattern of attack sees an adversary load a malicious resource into a program's standard path so that when a known command is executed then the system instead executes the malicious component. The adversary can either modify the search path a program uses, like a PATH variable or classpath, or they can manipulate resources on the path to point to their malicious components. 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.
-
Search Order Hijacking
An adversary exploits a weakness in an application's specification of external libraries to exploit the functionality of the loader where the process loading the library searches first in the same directory in which the process binary resides and then in other directories. Exploitation of this preferential search order can allow an attacker to make the loading process load the adversary's rogue library rather than the legitimate library. This attack can be leveraged with many different libraries and with many different loading processes. No forensic trails are left in the system's registry or file system that an incorrect library had been loaded.
