Name: Latte 3.0.20 Scanner

The Latte template engine, primarily utilized in PHP-based web applications, facilitates dynamic content rendering. Developers and organizations leverage it for its robust features and ease of integration into existing codebases. It plays a critical role in separating HTML generation from PHP logic, enhancing code maintainability and security. However, due to its extensive use and complexity, vulnerabilities within the Latte engine could pose serious security risks to applications employing it. Therefore, routine security checks and scans for known vulnerabilities are essential to protect the integrity and confidentiality of web applications using it. By adopting security measures proactively, developers can safeguard their assets against potential exploits and data breaches.

Server Side Template Injection (SSTI) represents a significant security flaw wherein an attacker may exploit template injection vulnerabilities to execute arbitrary code on the server. This type of vulnerability often occurs when user input is unsafely concatenated into templates and then executed within the application context. As a result, attackers could inject malicious scripts or commands that compromise server security and control. Incidents of SSTI can lead to data leakage, unauthorized access, and further attacks on connected systems. Identifying SSTI vulnerabilities early on can prevent such exploits and maintain the security posture of web applications. Addressing these issues requires comprehensive input validation and stringent template processing protocols.

The vulnerability checked involves introducing unsanitized data into Latte's template rendering process, potentially allowing malicious code execution. The vulnerable parameter is typically user-supplied data that hasn't been properly validated or sanitized. In technical terms, the attack vector might involve injecting server directives or commands within template syntax, which the engine executes. The exploit leverages Latte's template syntax parser, turning it into an attack surface when user inputs are improperly handled. The specific vulnerability targets the query part of HTTP requests, attempting to execute system commands via injected payloads. Understanding these technical details is crucial for formulating effective vulnerability mitigation strategies.

When malicious actors exploit Server Side Template Injection vulnerabilities, numerous damaging effects may ensue. The immediate risk involves unauthorized code execution on the server, which might lead to the disclosure of sensitive information or unauthorized system access. Furthermore, attackers could escalate privileges, install backdoors, or steal data, causing substantial harm to both users and systems. Such exploits might serve as a foothold for further attacks on related network infrastructure or lead to reputational damage for the affected organization. Therefore, recognizing the potential consequences underscores the necessity of promptly addressing SSTI vulnerabilities and implementing robust security mechanisms. Regular updates and patches, along with comprehensive security assessments, contribute to mitigating these risks.
