CVE-2021-3129 is a critical vulnerability affecting Facade Ignition versions prior to 2.5.2, as utilized in Laravel and other products. This vulnerability allows unauthenticated remote attackers to execute arbitrary code due to insecure usage of file_get_contents() and file_put_contents(). The vulnerability is particularly exploitable on sites running in debug mode with Laravel versions prior to 8.4.2.
The CVSS 3.1 score for this vulnerability is 9.8, indicating a critical severity. This high severity level highlights the potential impact on the confidentiality, integrity, and availability of affected systems.
With a low attack complexity and no privileges required for exploitation, this vulnerability poses significant risk to organizations that deploy affected versions of Ignition. The urgency for defenders is underscored by its inclusion in the Known Exploited Vulnerabilities (KEV) catalog, making immediate mitigation crucial.
Organizations should prioritize patching immediately to prevent exploitation and protect their environments from potential compromise.
Vulnerability Details
The official description of this vulnerability states that Ignition before 2.5.2 allows unauthenticated remote attackers to execute arbitrary code due to insecure usage of file_get_contents() and file_put_contents(). It is exploitable on sites using debug mode with Laravel versions prior to 8.4.2.
The vulnerability has a CVSS score of 9.8, classifying it as critical. This score indicates a significant risk to the confidentiality, integrity, and availability of affected systems.
The affected product is Ignition, developed by Facade, and this vulnerability was published on January 12, 2021.
Technical Analysis
The root cause of this vulnerability stems from insecure coding practices, particularly the improper handling of file operations which can lead to remote code execution. The attack vector is over the network, with low complexity required for an attacker to exploit it.
No privileges are required for exploitation, and user interaction is not necessary. The impact on confidentiality, integrity, and availability is classified as high, indicating the severe consequences of a successful attack.
Risk & Impact Analysis
Organizations using affected versions of Ignition are at a high risk of unauthorized access and data manipulation. The potential blast radius includes all systems leveraging vulnerable Ignition installations, especially those running in debug mode.
Given the nature of this vulnerability and its inclusion in the KEV catalog, organizations should address it in their priority patch cycle. The urgency is driven by the high CVSS score and the potential for exploitation by attackers.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | Yes |
Public PoC | Yes |
Actively Exploited | Yes |
Ransomware Use | Yes |
Affected Versions
All versions of Ignition prior to 2.5.2 are affected. Additionally, Laravel versions prior to 8.4.2 are also vulnerable when debug mode is enabled.
Mitigation & Remediation
To mitigate this vulnerability, organizations should apply the latest patches provided by Facade. Specifically, upgrading Ignition to version 2.5.2 or later is essential. For Laravel users, ensuring that the Laravel framework is updated to version 8.4.2 or higher while disabling debug mode can help secure the application.
In cases where patching is not immediately feasible, organizations should consider implementing additional network controls and monitoring to detect any attempts at exploitation.
