Analysis
by VulDB Data Team • 01/29/2023
The vulnerability identified as CVE-2018-25068 represents a critical security flaw in the devent globalpom-utils library version 4.5.0 and earlier, specifically within the createTmpDir function of the FileResourceManagerProvider.java file. This issue falls under the CWE-377 weakness category, which focuses on insecure temporary file creation practices that can lead to privilege escalation and unauthorized access to sensitive data. The vulnerability arises from improper handling of temporary file creation processes, where the application fails to adequately secure temporary directories and files, potentially allowing malicious actors to manipulate or gain access to system resources.
The technical flaw manifests in the insecure temporary file creation mechanism that lacks proper security controls during the temporary directory establishment process. When the createTmpDir function is invoked, it does not implement adequate measures to ensure that temporary directories are created with proper permissions and are isolated from potential attackers. This vulnerability enables attackers to exploit the temporary file handling mechanism through remote execution, as the flaw does not require local system access to be exploited. The attack vector operates by manipulating the temporary file creation process to either predict file locations, hijack temporary files, or create symbolic links that redirect file operations to unauthorized locations, thereby compromising system integrity and potentially escalating privileges.
The operational impact of this vulnerability extends beyond simple data exposure, as it can enable attackers to perform privilege escalation attacks and potentially gain unauthorized access to sensitive system resources. The remote exploit capability makes this vulnerability particularly dangerous as it allows adversaries to target systems without requiring physical access or local network presence. This weakness directly aligns with ATT&CK technique T1059.001, which involves executing malicious code through command-line interfaces, and T1078.004, which covers legitimate credentials in cloud environments. The vulnerability affects systems that rely on the globalpom-utils library for file resource management, potentially compromising the integrity of applications that utilize temporary file handling for various operations including configuration management, data processing, and temporary storage operations.
The recommended mitigation strategy involves upgrading the affected component to version 4.5.1, which includes the patch identified by commit hash 77a820bac2f68e662ce261ecb050c643bd7ee560. This upgrade addresses the insecure temporary file creation issue by implementing proper security controls during temporary directory establishment, including appropriate permission settings, secure file naming conventions, and isolation mechanisms. Organizations should also implement additional security measures such as monitoring for unauthorized temporary file creation, implementing proper file system permissions, and conducting regular security assessments of third-party libraries. The vulnerability's classification as critical underscores the importance of immediate remediation, as it provides attackers with a straightforward path to system compromise through remote exploitation without requiring elevated privileges or complex attack chains.
