IDoc View Arbitrary File Upload Scanner

IDoc View is a software platform used by individuals and organizations for online document previewing. It allows users to view documents in various formats through their web browsers without requiring additional software installations. Often implemented in business and educational environments, it provides a seamless way to display and share documents over the web. Users can easily access and review content, fostering enhanced collaboration and decision-making processes. The software integrates with different content management systems and serves as a bridge in document sharing workflows. Its utility in document visualization makes it a common component in document management solutions.

The Arbitrary File Upload vulnerability in IDoc View allows unauthorized individuals to upload potentially malicious files to the server. This security flaw can lead to unauthorized access and manipulation of files, affecting the integrity and security of the system. Upon successful exploitation, attackers could leverage the uploaded files to execute arbitrary code or scripts. This poses a significant risk to data confidentiality and operational continuity. The vulnerability underscores the importance of robust file validation and upload restrictions. It provides a vector for attackers to gain further access to the application or underlying systems.

Technical details reveal that the vulnerable endpoint is located at /html/2word, where inadequate validation allows arbitrary files to be uploaded. The parameter 'url' in the GET request is susceptible to manipulation, leading to the upload of crafted files. The absence of proper checks and balances in the file handling process exacerbates the vulnerability, exposing the system to potential abuse. Vulnerable response conditions include successful MD5 checksum matching and a 200 HTTP status code, confirming the upload success. The issue highlights the need for stringent input validation and access control mechanisms.

Exploiting this vulnerability could result in severe consequences, such as data breaches and unauthorized system modifications. Malicious actors might upload scripts or executable files to execute code remotely, compromising the server's security stance. Data integrity could be jeopardized, with potential leaks of sensitive information or significant service disruptions. Moreover, compromised systems can serve as launchpads for further attacks, extending the impact beyond the initial breach. Prevention measures are critical to safeguarding against these detrimental effects.
