CVE-2023-43655

Description

From CVE.org

Composer is a dependency manager for PHP. Users publishing a composer.phar to a public web-accessible server where the composer.phar can be executed as a php file may be subject to a remote code execution vulnerability if PHP also has `register_argc_argv` enabled in php.ini. Versions 2.6.4, 2.2.22 and 1.10.27 patch this vulnerability. Users are advised to upgrade. Users unable to upgrade should make sure `register_argc_argv` is disabled in php.ini, and avoid publishing composer.phar to the web as this is not best practice.

Understanding the Weakness (CWE)

Confidentiality

Technical Impact: Read Application Data

Many injection attacks involve the disclosure of important information -- in terms of both data sensitivity and usefulness in further exploitation.

Access Control

Technical Impact: Bypass Protection Mechanism

In some cases, injectable code controls authentication; this may lead to a remote vulnerability.

Other

Technical Impact: Alter Execution Logic

Injection attacks are characterized by the ability to significantly change the flow of a given process, and in some cases, to the execution of arbitrary code.

Integrity,Other

Technical Impact: Other

Data injection attacks lead to loss of data integrity in nearly all cases as the control-plane data injected is always incidental to data recall or writing.

Non-Repudiation

Technical Impact: Hide Activities

Often the actions performed by injected control code are unlogged.
