The Arbitrary File Read vulnerability present in UFIDA U8 CRM allows attackers to read sensitive files on the server where the software is installed. This type of vulnerability occurs when user-supplied input for file paths is not properly sanitized or validated, enabling malicious users to manipulate file access points. Through this vulnerability, unauthorized files can be accessed without permission, thereby compromising data confidentiality. This vulnerability particularly affects systems where sensitive files are stored in predictable locations and with insufficient access controls. Detecting and mitigating such vulnerabilities is crucial for protecting sensitive information from unauthorized read access.

Technically, the Arbitrary File Read vulnerability in UFIDA U8 CRM can be exploited through specific requests to the getemaildata.php endpoint. An attacker can send specially crafted HTTP requests to the said script, allowing them to specify a legitimate file path that the server will process and return in the response. The vulnerability arises due to inadequate checks for login and improper validation of the file path parameter. Without robust input validation, attackers can manipulate the input parameters to traverse directory structures and obtain the contents of critical system files, which are then included in the server response.

Exploiting this vulnerability allows attackers to access sensitive information such as system configuration files, user data files, and any other files that the application has read permissions for. This unauthorized access could lead to information leakage, enabling attackers to further exploit the system by obtaining credentials, gaining deeper access, or potentially implementing a more significant compromise. Other possible impacts include business data exposure, legal implications, and loss of customer trust.
