CVE-2024-52301 is a high-severity vulnerability affecting the Laravel framework, which is widely used for web applications. This vulnerability allows attackers to manipulate the environment used by the framework when specific configurations are present. When the register_argc_argv PHP directive is enabled, a specially crafted query string can alter the framework's behavior, potentially leading to unauthorized access or other malicious activities.
With a CVSS score of 8.7, this vulnerability poses a significant risk to organizations relying on the affected versions of Laravel. The exploitation of this vulnerability has been confirmed, indicating that organizations must take immediate action to mitigate potential risks. The urgency for defenders is heightened, given the potential impact of exploitation.
Organizations should prioritize patching immediately, as the vulnerability has been addressed in several versions of the Laravel framework. Specifically, it has been fixed in versions 6.20.45, 7.30.7, 8.83.28, 9.52.17, 10.48.23, and 11.31.0. Defenders should evaluate their systems to ensure they are not using vulnerable versions.
Failure to address this vulnerability could lead to severe consequences, including unauthorized access to sensitive data or manipulation of the web application's environment. Organizations are encouraged to stay vigilant and monitor their systems for any unusual activity that may indicate exploitation attempts.
Vulnerability Details
The Laravel framework is designed to facilitate web application development. However, when the register_argc_argv PHP directive is set to on, users can change the environment used by the framework through crafted query strings. This vulnerability allows an attacker to exploit this behavior, leading to potential integrity issues.
The vulnerability has been classified under CWE-88: Argument Injection or Modification. The affected versions include several releases of the Laravel framework, specifically prior to the aforementioned fixed versions. The exploitation of this vulnerability is facilitated through network vectors, with low attack complexity, no required privileges, and no user interaction.
The CVSS score reflects the severity of the vulnerability, indicating a high level of concern for organizations operating in environments using the Laravel framework. Organizations should take proactive steps to remediate affected systems.
Technical Analysis
The root cause of CVE-2024-52301 lies in the handling of the register_argc_argv directive in PHP. When this directive is enabled, it allows the framework to process command-line arguments, which can be exploited via crafted query strings in a web request. Attackers can manipulate these arguments to alter the behavior of the Laravel application.
This vulnerability can be exploited through network access, requiring low complexity for successful exploitation. Notably, no privileges are needed to launch an attack, and user interaction is also not necessary. The integrity impact of this vulnerability is classified as high, while confidentiality and availability impacts are assessed as none.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2024-52301 is significant, particularly for organizations that utilize Laravel in their web applications. The ability for attackers to manipulate the environment could lead to unauthorized data access or modification, which can have severe consequences for data integrity and overall application functionality.
Organizations should assess their exposure to this vulnerability by evaluating the versions of Laravel in use and implementing necessary patches. The urgency of addressing this vulnerability is underscored by its high CVSS score and confirmed exploitation.
With an EPSS score in the 98th percentile, the likelihood of exploitation in the wild is high, emphasizing the need for immediate action. Affected organizations could experience a wide blast radius, impacting not just the web application but potentially the entire underlying infrastructure.
