Horizon Alert
Summary of the vulnerability and why it matters
Craft CMS, a platform for building digital experiences, has a vulnerability that could allow for the execution of arbitrary code. This flaw exists when a specific PHP configuration setting, `register_argc_argv`, is enabled. If exploited, this could lead to unauthorized code execution on affected systems.
- Unspecified remote code execution vector.
- Remote code execution.
- Compromised systems and data.
Attack Path
How an attacker could exploit the issue
This vulnerability presents a remote code execution risk for organizations using Craft CMS when specific conditions are met. An attacker could exploit this by triggering a code injection vector. Successful exploitation would allow an attacker to gain control over affected systems, potentially leading to unauthorized access and manipulation of data.
- The PHP configuration `register_argc_argv` must be enabled.
- An attacker sends a request to the affected system.
- Code injection occurs, leading to remote code execution.
Live Threat
Current exploitation, exposure, and threat context
The identified vulnerability in Craft CMS presents a significant risk, enabling remote code execution under specific configuration conditions. This could allow attackers to compromise affected systems and potentially gain control over them. Organizations using Craft CMS should consider this a high-priority issue, especially if their `php.ini` configuration includes `register_argc_argv` enabled.
- Likely attacker skill level: Low
