AVCON6 System Management Platform Arbitrary File Download Scanner

AVCON6 is a system management platform commonly used by organizations to centralize and streamline their IT operations. It is typically employed by IT administrators to configure, monitor, and control various systems and applications within an enterprise. The platform aims to enhance operational efficiency by providing comprehensive tools for managing multiple systems from a single interface. Businesses leverage AVCON6 to ensure high availability and performance across their critical IT infrastructure. Its use is prevalent in sectors with large, complex IT environments requiring robust management solutions. AVCON6 offers features such as monitoring, reporting, and automation to facilitate optimal IT service delivery.

The vulnerability in question involves an Arbitrary File Download weakness in the AVCON6 system management platform. This flaw allows attackers to download files arbitrarily from the server, potentially accessing sensitive and critical data. It arises due to inadequate validation of user inputs in the org_execl_download.action endpoint. Exploiting this vulnerability could enable unauthorized access to a variety of important files stored on the compromised server. Such a security flaw can be highly damaging, as it breaches confidentiality and integrity safeguards. The impact of this vulnerability is further exacerbated by the high sensitivity of data managed by AVCON6.

Technically, the vulnerability exploits insufficient input validation mechanisms present in the org_execl_download.action endpoint of AVCON6. By crafting a malicious request, an attacker can traverse directories and download files without authorization. In particular, the use of path traversal techniques within the filename parameter allows access to critical system files like /etc/passwd. The response headers indicating a successful download and specific MIME types can further confirm the exploit's success. Attackers leveraging this vulnerability might also use other sensitive endpoints to extract confidential data from the AVCON6 platform.

Successful exploitation of this Arbitrary File Download vulnerability could lead to unauthorized data exposure, resulting in both financial and reputational damage for affected organizations. Critical files on the server could be compromised, including configurations and private information about infrastructure components. Pillaging this data might empower attackers to conduct further attacks, such as privilege escalation or lateral movement within the network. The exploitation might also enable the insertion of malicious files, potentially leading to broader security breaches or the establishment of persistent access to the system for continual exploitation.
