CVE-2022-1292 : Vulnerability Insights and Analysis

This article provides insights into CVE-2022-1292, a vulnerability related to the c_rehash script in OpenSSL.

Understanding CVE-2022-1292

CVE-2022-1292 involves a command injection vulnerability in the c_rehash script distributed by some operating systems, allowing attackers to execute arbitrary commands with script privileges.

What is CVE-2022-1292?

The c_rehash script fails to properly sanitize shell metacharacters, enabling command injection. It is recommended to replace it with the OpenSSL rehash command line tool.

The Impact of CVE-2022-1292

The vulnerability poses a significant security risk, enabling unauthorized command execution on affected systems using the c_rehash script.

Technical Details of CVE-2022-1292

CVE-2022-1292 affects various versions of OpenSSL as follows:

Vulnerability Description

The c_rehash script allows command injection due to inadequate sanitization of shell metacharacters, enabling potential exploitation by threat actors.

Affected Systems and Versions

OpenSSL versions 3.0.0, 3.0.1, 3.0.2, 1.1.1-1.1.1n, and 1.0.2-1.0.2zd are affected, while the issue has been resolved in OpenSSL 3.0.3, 1.1.1o, and 1.0.2ze.

Exploitation Mechanism
