An arbitrary file read vulnerability allows unauthorized attackers to access files on a vulnerable server without permission. This kind of vulnerability can lead to significant information disclosure if exploited. Attackers could potentially access sensitive files containing valuable information. The issue often arises from improper access control mechanisms that fail to restrict file access. An exploit can reveal sensitive server configurations and operational details that should remain confidential. Such vulnerabilities can undermine trust in a secure enterprise system if left unaddressed.

The vulnerability in Jinhe OA C6 is found in the download.jsp file, where parameters are improperly handled. The ‘filename’ parameter, when manipulated, allows attackers to access arbitrary files on the server. The vulnerability can be exploited by sending requests that navigate to sensitive directories. Successful exploitation requires the attacker to craft requests to obtain improperly protected files, such as configuration or password files. If the server’s response confirms the presence and content of these files, sensitive data exposure is likely. Exploitation relies on deficient validation of user input pertaining to file paths.

If exploited, this vulnerability can lead to unauthorized data exposure, providing attackers access to confidential information contained in server files. Information such as configuration files could reveal system secrets or passwords, compromising security. This can lead to a domino effect, where further vulnerabilities are exploited using the disclosed information. Legitimate users' data privacy could be breached, affecting business integrity. Exploitation can result in leveraged attacks, causing further damage and disrupting services.
