Description Preview

The vulnerability, known as envvars (aka envvars-std), exists in the Apache HTTP Server before version 2.4.2. It stems from the placement of a zero-length directory name in the LD_LIBRARY_PATH, which can be exploited by local users to elevate their privileges. By introducing a malicious DSO (Dynamic Shared Object) in the current working directory during the execution of apachectl, attackers can execute arbitrary code with elevated privileges.

Overview

This vulnerability in the Apache HTTP Server before version 2.4.2 allows local users to escalate their privileges by manipulating the LD_LIBRARY_PATH environment variable. By placing a zero-length directory name in this variable, a malicious user can load a Trojan horse DSO to execute arbitrary code with elevated privileges.

Remediation

To mitigate this vulnerability, users are advised to upgrade their Apache HTTP Server to version 2.4.2 or later. By updating to a patched version, the zero-length directory name issue in LD_LIBRARY_PATH is addressed, preventing local users from exploiting the vulnerability to gain elevated privileges.
