Horizon Alert
Summary of the vulnerability and why it matters
A vulnerability in the Apache Camel FTP component could allow an attacker to access, delete, or rename files outside of the intended directory on a remote server. This occurs because the component improperly handles file paths received from the server, potentially enabling actions on files beyond the configured polling directory.
- Allows unauthorized file access or modification.
- Impacts systems using remote file operations.
- Confirm if remote file access is used.
Attack Path
How an attacker could exploit the issue
An attacker can exploit this vulnerability by manipulating the file names received from an FTP server. If an attacker can control the FTP server's directory listing, they can trick the Apache Camel FTP component into reading, deleting, or renaming files outside of its intended polling directory. This is possible because the component concatenates the configured directory with the file name without proper validation, allowing it to access files beyond its boundaries using the endpoint's credentials.
- Attacker controls FTP server listing.
- Component concatenates pathnames insecurely.
- Unrestricted file access on the remote server.
Live Threat
Current exploitation, exposure, and threat context
This vulnerability in Apache Camel's FTP component could allow an attacker to read, delete, or rename files outside of the intended polling directory on the remote FTP server. This occurs when the server returns specially crafted directory listing entries that trick Camel into constructing an absolute file path that escapes the configured directory. This could lead to unauthorized access and modification of files the Camel application is not supposed to interact with.
- Remote files and directories could be affected.
- Malicious server responses could cause path traversal.
- Unauthorized file access and modification may occur.
Operational Fix
Recommended remediation, mitigation, and detection steps
The Apache Camel FTP component's path traversal vulnerability requires immediate attention from teams managing integrations that use this component. The first step is to identify all instances of affected Camel versions, determine their exposure to potentially malicious FTP servers or compromised server environments, and confirm which integrations are business-critical. Once identified and prioritized, a plan for remediation or mitigation should be developed, involving coordination with application owners and potentially vendor management if the component is part of a third-party solution.
- Application owners and platform teams should own this issue.
- Verify all Camel FTP consumer integrations.
- Plan remediation or implement temporary risk reduction.
