CVE-2019-5629 (GCVE-0-2019-5629)

Vulnerability from cvelistv5 – Published: 2019-07-13 00:15 – Updated: 2024-09-16 22:45
VLAI
Summary
Rapid7 Insight Agent, version 2.6.3 and prior, suffers from a local privilege escalation due to an uncontrolled DLL search path. Specifically, when Insight Agent 2.6.3 and prior starts, the Python interpreter attempts to load python3.dll at "C:\DLLs\python3.dll," which normally is writable by locally authenticated users. Because of this, a malicious local user could use Insight Agent's startup conditions to elevate to SYSTEM privileges. This issue was fixed in Rapid7 Insight Agent 2.6.4.
Severity
7.8 (High)

CVE-2019-3881 (GCVE-0-2019-3881)

Vulnerability from cvelistv5 – Published: 2020-09-04 00:00 – Updated: 2024-08-04 19:19
VLAI
Summary
Bundler prior to 2.1.0 uses a predictable path in /tmp/, created with insecure permissions as a storage location for gems, if locations under the user's home directory are not available. If Bundler is used in a scenario where the user does not have a writable home directory, an attacker could place malicious code in this directory that would be later loaded and executed.

CVE-2019-3750 (GCVE-0-2019-3750)

Vulnerability from cvelistv5 – Published: 2019-12-03 20:20 – Updated: 2024-09-16 23:11
VLAI
Summary
Dell Command Update versions prior to 3.1 contain an Arbitrary File Deletion Vulnerability. A local authenticated malicious user with low privileges potentially could exploit this vulnerability to delete arbitrary files by creating a symlink from the "Temp\IC\ICDebugLog.txt" to any targeted file. This issue occurs because of insecure handling of Temp directory permissions that were set incorrectly.

CVE-2019-3745 (GCVE-0-2019-3745)

Vulnerability from cvelistv5 – Published: 2019-10-07 18:21 – Updated: 2024-09-17 04:14
VLAI
Summary
The vulnerability is limited to the installers of Dell Encryption Enterprise versions prior to 10.4.0 and Dell Endpoint Security Suite Enterprise versions prior to 2.4.0. This issue is exploitable only during the installation of the product by an administrator. A local authenticated low privileged user potentially could exploit this vulnerability by staging a malicious DLL in the search path of the installer prior to its execution by a local administrator. This would cause loading of the malicious DLL, which would allow the attacker to execute arbitrary code in the context of an administrator.

Title
Cisco Advanced Malware Protection for Endpoints on Windows DLL Preloading Vulnerability
Summary
A vulnerability in the DLL loading component of Cisco Advanced Malware Protection (AMP) for Endpoints on Windows could allow an authenticated, local attacker to disable system scanning services or take other actions to prevent detection of unauthorized intrusions. To exploit this vulnerability, the attacker would need to have administrative credentials on the Windows system. The vulnerability is due to the improper validation of resources loaded by a system process at run time. An attacker could exploit this vulnerability by crafting a malicious DLL file and placing it in a specific location on the targeted system. A successful exploit could allow the attacker to disable the targeted system's scanning services and ultimately prevent the system from being protected from further intrusion. There are no workarounds that address this vulnerability.

Mitigation
Architecture and Design Implementation

Strategy: Attack Surface Reduction

Hard-code the search path to a set of known-safe values (such as system directories), or only allow them to be specified by the administrator in a configuration file. Do not allow these settings to be modified by an external party. Be careful to avoid related weaknesses such as CWE-426 and CWE-428.

Mitigation
Implementation

Strategy: Attack Surface Reduction

When invoking other programs, specify those programs using fully-qualified pathnames. While this is an effective approach, code that uses fully-qualified pathnames might not be portable to other systems that do not use the same pathnames. The portability can be improved by locating the full-qualified paths in a centralized, easily-modifiable location within the source code, and having the code refer to these paths.

Mitigation
Implementation

Strategy: Attack Surface Reduction

Remove or restrict all environment settings before invoking other programs. This includes the PATH environment variable, LD_LIBRARY_PATH, and other settings that identify the location of code libraries, and any application-specific search paths.

Mitigation
Implementation

Check your search path before use and remove any elements that are likely to be unsafe, such as the current working directory or a temporary files directory. Since this is a denylist approach, it might not be a complete solution.

Mitigation
Implementation

Use other functions that require explicit paths. Making use of any of the other readily available functions that require explicit paths is a safe way to avoid this problem. For example, system() in C does not require a full path since the shell can take care of finding the program using the PATH environment variable, while execl() and execv() require a full path.

CAPEC-38: 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.

CAPEC-471: 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.
