Overview
org.apache.camel:camel-core is a powerful open source integration framework based on known Enterprise Integration Patterns with powerful bean integration.
Affected versions of this package are vulnerable to Directory Traversal. The file producer allows writing files to directories outside its starting directory.
Details
A Directory Traversal attack (also known as path traversal) aims to access files and directories that are stored outside the intended folder. By manipulating files with "dot-dot-slash (../)" sequences and its variations, or by using absolute file paths, it may be possible to access arbitrary files and directories stored on file system, including application source code, configuration, and other critical system files.
Directory Traversal vulnerabilities can be generally divided into two types:
- Information Disclosure: Allows the attacker to gain information about the folder structure or read the contents of sensitive files on the system.
st
is a module for serving static files on web pages, and contains a vulnerability of this type. In our example, we will serve files from the public
route.
If an attacker requests the following URL from our server, it will in turn leak the sensitive private key of the root user.
curl http://localhost:8080/public/%2e%2e/%2e%2e/%2e%2e/%2e%2e/%2e%2e/root/.ssh/id_rsa
Note %2e
is the URL encoded version of .
(dot).
- Writing arbitrary files: Allows the attacker to create or replace existing files. This type of vulnerability is also known as
Zip-Slip
.
One way to achieve this is by using a malicious zip
archive that holds path traversal filenames. When each filename in the zip archive gets concatenated to the target extraction folder, without validation, the final path ends up outside of the target folder. If an executable or a configuration file is overwritten with a file containing malicious code, the problem can turn into an arbitrary code execution issue quite easily.
The following is an example of a zip
archive with one benign file and one malicious file. Extracting the malicious file will result in traversing out of the target folder, ending up in /root/.ssh/
overwriting the authorized_keys
file:

Remediation
Upgrade org.apache.camel:camel-core
to version 2.21.5, 2.22.3, 2.23.1 or higher.

Overview
Affected versions of this package are vulnerable to Observable Discrepancy due to the timing difference between exceptions thrown when processing RSA key exchange handshakes, AKA Marvin.
Note: The implemented fix mitigates the leakage of data via the PKCS#1 interface, but does not fully alleviate the side-channel as it allows cases in which the padding check fails but the handshake succeeds.
Remediation
Upgrade org.bouncycastle:bcprov-jdk18on
to version 1.78 or higher.

Overview
Affected versions of this package are vulnerable to Observable Timing Discrepancy via the PKCS#1 1.5 and OAEP decryption process. An attacker can recover ciphertexts via a side-channel attack by exploiting the Marvin security flaw. The PKCS#1 1.5 attack vector leaks data via javax.crypto.Cipher
exceptions and the OAEP interface vector leaks via the bit size of the decrypted data.
Remediation
Upgrade org.bouncycastle:bcprov-jdk18on
to version 1.78 or higher.

Overview
commons-io:commons-io is a The Apache Commons IO library contains utility classes, stream implementations, file filters, file comparators, endian transformation classes, and much more.
Affected versions of this package are vulnerable to Directory Traversal via calling the method FileNameUtils.normalize using an improper string like //../foo
or \\..\foo
, which may allow access to files in the parent directory.
