CVE-2024-11680 Scanner

ProjectSend is widely used within organizations to manage and share files among team members and external clients securely. It is an open-source solution, favored for its user-friendly interface and customization capabilities. The software is primarily deployed in environments where there is a need for controlled access to shared resources. With ProjectSend, administrators can assign permissions and control file downloads, making it an essential tool in collaborative projects. The flexibility in managing different user roles adds to its popularity among small to medium enterprises. Its deployment is common in sectors where data privacy and controlled sharing are of utmost importance, such as legal and consultancy firms.

The Improper Access Control vulnerability found in ProjectSend pertains to insufficient enforcement of authorization controls that could lead to unauthorized execution of sensitive tasks. This flaw allows attackers to exploit certain functions within the application without appropriate permissions. Unauthorized users may manipulate registration settings and modify the whitelist of allowed file extensions. Such vulnerabilities emerge when applications fail to validate user roles correctly, leading to potential escalation of privileges. This issue could pave the way for attackers to execute arbitrary PHP code, compromising the host server. Known as CVE-2024-11680, it is a critical vulnerability that requires immediate remediation due to its potential impact on data integrity and confidentiality.

The technical details of this Improper Access Control vulnerability reveal that it stems from inadequate checks on user permissions within the ProjectSend software. A malicious actor can interact with endpoints such as /options.php without having valid credentials. By bypassing authentication, they gain unauthorized access, allowing them to adjust critical settings like user registration and file extension whitelist. Such endpoints lack proper validation, making them susceptible to unauthorized manipulation. This bypass could be exploited to execute PHP code on the server, thus compromising the safety of the application and the data it manages. This flaw reflects vulnerabilities often encountered in complex software systems when comprehensive security testing is not thoroughly conducted.

If exploited, this vulnerability could have significant consequences, including unauthorized control over application settings and the execution of arbitrary code. An attacker could alter configurations, potentially leading to further security breaches and unauthorized exposure of sensitive information. This could undermine the confidentiality and integrity of data shared within ProjectSend. The arbitrary execution of code may even allow attackers to inject their malware or backdoors, extending their control over the compromised system. The impact extends beyond immediate unauthorized access, potentially resulting in long-term damage and data loss.
