CVE-2025-53363 in dpanel
Summary
by MITRE • 08/22/2025
dpanel is an open source server management panel written in Go. In versions 1.2.0 through 1.7.2, dpanel allows authenticated users to read arbitrary files from the server via the /api/app/compose/get-from-uri API endpoint. The vulnerability exists in the GetFromUri function in app/application/http/controller/compose.go, where the uri parameter is passed directly to os.ReadFile without proper validation or access control. A logged-in attacker can exploit this flaw to read sensitive files from the host system, leading to information disclosure. No patched version is available as of this writing.

The vulnerability CVE-2025-53363 affects dpanel, an open source server management panel developed in Go, specifically impacting versions ranging from 1.2.0 through 1.7.2. This issue represents a critical information disclosure flaw that stems from inadequate input validation within the application's API layer. The vulnerability manifests through the /api/app/compose/get-from-uri endpoint, which exposes a path traversal vulnerability in the GetFromUri function located in app/application/http/controller/compose.go. The flaw occurs when the uri parameter is directly passed to os.ReadFile without any sanitization or access control measures, creating a direct attack vector for authenticated users to access arbitrary files on the host system.
The technical implementation of this vulnerability aligns with CWE-22, which describes improper limitation of a pathname to a restricted directory, commonly known as path traversal. The attack exploits the lack of proper input validation by allowing authenticated users to craft malicious URI requests that bypass normal file access controls. When an attacker successfully exploits this vulnerability, they can retrieve sensitive files including configuration files, database credentials, private keys, and other system artifacts that may contain confidential information. This represents a significant escalation from a simple authenticated access point to a potential full system compromise, as the attacker can now exfiltrate data that should remain restricted to authorized personnel only.
From an operational perspective, this vulnerability creates severe implications for system security and compliance requirements. The impact extends beyond simple information disclosure to potentially enable further attacks including credential theft, system reconnaissance, and privilege escalation. Attackers can leverage this vulnerability to gather intelligence about the underlying infrastructure, application configuration, and system architecture. The lack of a patched version at the time of reporting compounds the risk, leaving affected systems exposed indefinitely. Organizations using dpanel versions within the affected range face potential data breaches, regulatory compliance violations, and increased attack surface that could facilitate more sophisticated attacks. The vulnerability's exploitation requires only authenticated access, which means that any user with legitimate credentials could potentially abuse this flaw, making it particularly dangerous in environments where user access is not strictly controlled.
Mitigation strategies for this vulnerability should focus on immediate remediation through input validation and access control implementation. Organizations should implement proper URI sanitization and path validation before any file operations are performed, ensuring that all user-provided input is properly normalized and checked against a whitelist of allowed paths. The recommended approach involves implementing a secure file access mechanism that validates all file paths and prevents traversal attacks. Additionally, organizations should consider implementing principle of least privilege access controls, ensuring that only necessary users have access to the affected API endpoints. The ATT&CK framework categorizes this vulnerability under T1566, which covers credential harvesting through social engineering, but in this case represents an internal attack vector where authenticated users exploit legitimate API access points. Network segmentation and monitoring of API access patterns can help detect potential exploitation attempts. Organizations should also consider implementing automated security scanning tools that can identify similar vulnerabilities in their codebase and ensure that all file operations include proper validation mechanisms to prevent unauthorized file access.
