CyberRota Analysis

AI-Generated

The OpenSSL package versions up to 1.4.8 are vulnerable due to the insecure handling of the steganography password, which is exposed in the command line arguments of a child process, allowing any local user to access it via the /proc filesystem. This vulnerability could lead to unauthorized access to sensitive information, particularly for applications relying on this package for encryption. Organizations using affected versions should prioritize upgrading to version 1.4.9 or later to mitigate the risk of local privilege escalation and data exposure.

Original NVD Description

In openssl_encrypt (pip package openssl-encrypt) versions <= 1.4.8, the desktop GUI passes the steganography password to the CLI child process on the command line via the --stego-password argument (on both encrypt and decrypt paths) instead of via an environment variable as done for the main password. Any local user can read the steganography password from /proc/<pid>/cmdline for the lifetime of the subprocess. Fixed in 1.4.9.
