Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

CVE-2022-1292

High
9.8/10

Summary

The c_rehash script does not properly sanitize shell metacharacters to prevent command injection. This script is distributed by some operating systems in a manner where it is automatically executed. On such operating systems, an attacker could execute arbitrary commands with the privileges of the script. The use of the c_rehash script is considered obsolete and should be replaced by the OpenSSL rehash command-line tool.The vulnerability affects OpenSSL versions prior to 1.0.2ze (premium support customers only), 1.1.x prior to 1.1.1o and 3.0.x prior to 3.0.3.

CWE-78 - OS Command Injection

The OS command injection weakness (also known as shell injection) is a vulnerability which enables an attacker to run arbitrary OS commands on a server. This is done by modifying the intended downstream OS command and injecting arbitrary commands, enabling the execution of unauthorized OS commands. This has the potential to fully compromise the application along with all of its data, and, if the compromised process does not follow the principle of least privileges, it may compromise other parts of the hosting infrastructure as well. This weakness is listed as number ten in the 'CWE Top 25 Most Dangerous Software Weaknesses'.
