The Arbitrary File Read vulnerability in Tongda OA V2017 can allow unauthorized users to access sensitive files within the server infrastructure. This vulnerability arises from improper handling of file paths in the video_file.php script, which may be exploited to access files without validation. An attacker can construct a URL that accesses unintended paths on the server, potentially disclosing confidential information such as configuration files or user data. The flaw is classified under improper file processes, as it stems from the software failing to securely process file paths. Arbitrary File Read vulnerabilities pose significant security risks, as they could lead to privacy breaches and unauthorized exposure of sensitive information. To mitigate the risks, it is crucial to address the underlying path validation issues in the affected scripts.

Technical details regarding the vulnerability involve manipulating the parameters 'MEDIA_DIR' and 'MEDIA_NAME' within the video_file.php script. Attackers leverage these parameters to traverse directories and access files outside the intended directory structure. This attack exploits a lack of input validation, whereby attackers append "../../../../" sequences to access critical files, such as configuration files. The match condition includes verifying the presence of specific words '$ROOT_PATH' and '$ATTACH_PATH' in the server response and a status code of 200, indicating successful file access. The lack of sufficient directory traversal prevention mechanisms allows attackers to bypass security controls and access sensitive data.

Exploiting the Arbitrary File Read vulnerability can have severe consequences, including unauthorized access to sensitive information stored on the server. Malicious actors could gain insights into the server's configuration, user credentials, or application structure, leading to potential breaches or system compromise. The disclosure of sensitive files can facilitate further exploitation, including privilege escalation or lateral movement within the network. This vulnerability undermines the confidentiality and integrity of data stored in the system, posing a substantial risk to the affected organization’s data security. Mitigating this risk requires addressing file access controls and implementing robust input validation measures.
