CVE-2025-1982 in Ready
Summary
by MITRE • 04/16/2025
Local File Inclusion vulnerability in Ready's attachment upload panel allows low privileged user to provide link to a local file using the file:// protocol thus allowing the attacker to read content of the file. This vulnerability can be use to read content of system files.

The vulnerability identified as CVE-2025-1982 represents a critical local file inclusion flaw within Ready's attachment upload functionality that fundamentally compromises system security through improper input validation. This weakness exists in the file handling mechanism where the application fails to adequately sanitize user-provided file paths, particularly when processing URLs that utilize the file:// protocol. The vulnerability specifically affects the attachment upload panel, which serves as a legitimate interface for users to submit files to the system, yet this functionality becomes a vector for malicious exploitation when inadequate validation permits arbitrary local file access.
The technical implementation of this vulnerability stems from the application's failure to properly validate and filter input parameters that control file access operations. When a user submits a file path through the upload interface, the system does not sufficiently verify that the requested file location falls within acceptable boundaries or that the file:// protocol is being used appropriately. This lack of input sanitization creates an opportunity for attackers to manipulate the file access mechanism by providing malicious file paths that reference local system files. The vulnerability operates under CWE-22 which classifies it as improper limitation of a pathname to a restricted directory, commonly known as path traversal attacks that allow unauthorized access to restricted files and directories.
The operational impact of this vulnerability extends far beyond simple information disclosure, as it provides attackers with the capability to read arbitrary system files that may contain sensitive data such as configuration files, user credentials, application source code, or system logs. Low privileged users who can access the attachment upload panel can exploit this flaw to gain unauthorized access to system resources that should remain protected. The implications are particularly severe because the vulnerability does not require elevated privileges to exploit, making it accessible to users who normally would not have access to such sensitive information. This could lead to complete system compromise through the exposure of critical system files, database connection strings, or application configuration details that could be leveraged for further attacks.
Security professionals should consider this vulnerability in the context of the ATT&CK framework under the technique T1083 - File and Directory Discovery, where adversaries attempt to gather information about files and directories on a compromised system. The vulnerability enables attackers to systematically enumerate and access local files that may contain sensitive information, potentially leading to privilege escalation or lateral movement within the network. Additionally, the flaw aligns with T1566 - Phishing as a method for initial access, since attackers may use this vulnerability to gather intelligence about the target system before launching more sophisticated attacks. Organizations should implement comprehensive input validation controls, including strict whitelisting of acceptable file paths, proper protocol validation, and robust access controls that prevent unauthorized file access regardless of user privileges. The mitigation strategy should include immediate patching of the affected application, implementation of web application firewalls that can detect and block file:// protocol usage in file upload contexts, and comprehensive monitoring for suspicious file access patterns that may indicate exploitation attempts.
