computer vulnerability note 22309

MuleSoft Mule ESB: external XML entity injection

Synthesis of the vulnerability

An attacker can transmit malicious XML data to MuleSoft Mule ESB, in order to read a file, scan sites, or trigger a denial of service.
Impacted products: Mule ESB.
Severity: 2/4.
Consequences: data reading, denial of service on service.
Provenance: document.
Creation date: 03/04/2017.
Identifiers: VIGILANCE-VUL-22309.

Description of the vulnerability

XML data can contain external entities (DTD):
  <!ENTITY name SYSTEM "file">
  <!ENTITY name SYSTEM "http://server/file">
A program which reads these XML data can replace these entities by data coming from the indicated file. When the program uses XML data coming from an untrusted source, this behavior leads to:
 - content disclosure from files of the server
 - private web site scan
 - a denial of service by opening a blocking file
This feature must be disabled to process XML data coming from an untrusted source.

However, the MuleSoft Mule ESB parser allows external entities.

An attacker can therefore transmit malicious XML data to MuleSoft Mule ESB, in order to read a file, scan sites, or trigger a denial of service.

Description of the vulnerability

The Apache Commons Collections library is used by several Java applications.

A Java Gadgets ("gadget chains") object can contain Transformers, with an "exec" string containing a shell command which is run with the Java.lang.Runtime.exec() method. When raw data are unserialized, the readObject() method is thus called to rebuild the Gadgets object, and it uses InvokerTransformer, which runs the indicated shell command.

It can be noted that other classes (CloneTransformer, ForClosure, InstantiateFactory, InstantiateTransformer, PrototypeCloneFactory, PrototypeSerializationFactory, WhileClosure) also execute a shell command from raw data to deserialize.

However, several applications publicly expose (before authentication) the Java unserialization feature.

An attacker can therefore send a malicious serialized Gadget Chain object to a Java application using Apache Commons Collections, in order to run shell code.

Identifiers: 1968485, 1972455, 9010041, 9010044, BSA-2016-002, cpuapr2018, cpujan2017, cpujan2018, cpujan2019, cpujul2015, cpujul2017, cpujul2018, cpuoct2017, CVE-2015-2613, CVE-2015-7940, DSA-3417-1, FEDORA-2015-7d95466eda, NTAP-20150715-0001, NTAP-20151028-0001, openSUSE-SU-2015:1911-1, RHSA-2016:2035-01, RHSA-2016:2036-01, USN-3727-1, VIGILANCE-VUL-18168.

Description of the vulnerability

The Bouncy Castle and Oracle Java products implement algorithms based on elliptic curves.

However, if the client forces the server to compute a common secret based on points located outside the chosen curve, he can progressively guess the full server key.

An attacker can therefore use a vulnerability in the elliptic curve implementation of Bouncy Castle and Oracle Java, in order to obtain sensitive information.

Apache HttpComponents HttpClient: denial of service via Timeout

Synthesis of the vulnerability

An attacker owning a malicious server can stop responding, to block clients using Apache HttpComponents HttpClient, in order to trigger a denial of service.
Impacted products: Apache HttpClient, Fedora, QRadar SIEM, Mule ESB, Ubuntu.
Severity: 2/4.
Consequences: denial of service on service.
Provenance: internet server.
Creation date: 02/10/2015.

Description of the vulnerability

The Apache HttpComponents HttpClient product implements a web client

However, there is no timeout during the connection state to a server.

An attacker owning a malicious server can therefore stop responding, to block clients using Apache HttpComponents HttpClient, in order to trigger a denial of service.
