Vulnerability details
The vulnerability allows a remote attacker to read, delete or rename files outside the configured remote polling directory using the endpoint's credentials.
The vulnerability exists due to improper limitation of a pathname to a restricted directory in Apache Camel's camel-ftp remote-file consumers when resolving file names supplied in remote directory listings without path normalization or containment checks. A remote attacker can supply a listing entry containing directory traversal segments through a malicious server, or rewrite an unprotected FTP listing response in transit, to cause file operations outside the configured polling directory.
