CWE CWE-200
CAPEC
  • Subverting Environment Variable Values
    The attacker directly or indirectly modifies environment variables used by or controlling the target software. The attacker's goal is to cause the target software to deviate from its expected operation in a manner that benefits the attacker.
  • Footprinting
    An attacker engages in probing and exploration activity to identify constituents and properties of the target. Footprinting is a general term to describe a variety of information gathering techniques, often used by attackers in preparation for some attack. It consists of using tools to learn as much as possible about the composition, configuration, and security mechanisms of the targeted application, system or network. Information that might be collected during a footprinting effort could include open ports, applications and their versions, network topology, and similar information. While footprinting is not intended to be damaging (although certain activities, such as network scans, can sometimes cause disruptions to vulnerable applications inadvertently) it may often pave the way for more damaging attacks.
  • Exploiting Trust in Client (aka Make the Client Invisible)
    An attack of this type exploits a programs' vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by placing themselves in the communication channel between client and server such that communication directly to the server is possible where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
  • Browser Fingerprinting
    An attacker carefully crafts small snippets of Java Script to efficiently detect the type of browser the potential victim is using. Many web-based attacks need prior knowledge of the web browser including the version of browser to ensure successful exploitation of a vulnerability. Having this knowledge allows an attacker to target the victim with attacks that specifically exploit known or zero day weaknesses in the type and version of the browser used by the victim. Automating this process via Java Script as a part of the same delivery system used to exploit the browser is considered more efficient as the attacker can supply a browser fingerprinting method and integrate it with exploit code, all contained in Java Script and in response to the same web page request by the browser.
  • Session Credential Falsification through Prediction
    This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.
  • Reusing Session IDs (aka Session Replay)
    This attack targets the reuse of valid session ID to spoof the target system in order to gain privileges. The attacker tries to reuse a stolen session ID used previously during a transaction to perform spoofing and session hijacking. Another name for this type of attack is Session Replay.
  • Using Slashes in Alternate Encoding
    This attack targets the encoding of the Slash characters. An attacker would try to exploit common filtering problems related to the use of the slashes characters to gain access to resources on the target host. Directory-driven systems, such as file systems and databases, typically use the slash character to indicate traversal between directories or other container components. For murky historical reasons, PCs (and, as a result, Microsoft OSs) choose to use a backslash, whereas the UNIX world typically makes use of the forward slash. The schizophrenic result is that many MS-based systems are required to understand both forms of the slash. This gives the attacker many opportunities to discover and abuse a number of common filtering problems. The goal of this pattern is to discover server software that only applies filters to one version, but not the other.

    description Updated packages that provide Red Hat JBoss Enterprise Application Platform 6.4.0, and fix multiple security issues, several bugs, and add various enhancements, are now available for Red Hat Enterprise Linux 5. Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. Red Hat JBoss Enterprise Application Platform 6 is a platform for Java applications based on JBoss Application Server 7. It was found that a prior countermeasure in Apache WSS4J for Bleichenbacher's attack on XML Encryption (CVE-2011-2487) threw an exception that permitted an attacker to determine the failure of the attempted attack, thereby leaving WSS4J vulnerable to the attack. The original flaw allowed a remote attacker to recover the entire plain text form of a symmetric key. (CVE-2015-0226) It was found that Apache WSS4J permitted bypass of the requireSignedEncryptedDataElements configuration property via XML Signature wrapping attacks. A remote attacker could use this flaw to modify the contents of a signed request. (CVE-2015-0227) It was discovered that a JkUnmount rule for a subtree of a previous JkMount rule could be ignored. This could allow a remote attacker to potentially access a private artifact in a tree that would otherwise not be accessible to them. (CVE-2014-8111) A flaw was found in the way PicketLink's Service Provider and Identity Provider handled certain requests. A remote attacker could use this flaw to log to a victim's account via PicketLink. (CVE-2015-0277) It was found that the Command Line Interface, as provided by Red Hat Enterprise Application Platform, created a history file named .jboss-cli-history in the user's home directory with insecure default file permissions. This could allow a malicious local user to gain information otherwise not accessible to them. (CVE-2014-3586) The CVE-2015-0277 issue was discovered by Ondrej Kotek of Red Hat. This release of JBoss Enterprise Application Platform also includes bug fixes and enhancements. Documentation for these changes will be available shortly from the JBoss Enterprise Application Platform 6.4.0 Release Notes, linked to in the References. All users who require JBoss Enterprise Application Platform 6.4.0 on Red Hat Enterprise Linux 5 should install these new packages. The JBoss server process must be restarted for the update to take effect.

    description Based on the Server response header, the installation of the JK Connector (mod_jk) in Apache Tomcat listening on the remote host is version 1.2.x prior to 1.2.41. It is, therefore, affected by an information disclosure vulnerability due to improper handling of the 'JkUnmount' directive and multiple, adjacent slashes in requests. A remote attacker can exploit this to access restricted private artifacts, resulting in the disclosure of sensitive information. Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

    description An update for Red Hat JBoss Web Server 2.1.0 that fixes two security issues is now available for Red Hat Enterprise Linux 5, 6, and 7. Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. Red Hat JBoss Web Server is a fully integrated and certified set of components for hosting Java web applications. It is comprised of the Apache HTTP Server, the Apache Tomcat Servlet container, Apache Tomcat Connector (mod_jk), JBoss HTTP Connector (mod_cluster), Hibernate, and the Tomcat Native library. A flaw was found in the way the mod_cluster manager processed certain MCMP messages. An attacker with access to the network from which MCMP messages are allowed to be sent could use this flaw to execute arbitrary JavaScript code in the mod_cluster manager web interface. (CVE-2015-0298) It was discovered that a JkUnmount rule for a subtree of a previous JkMount rule could be ignored. This could allow a remote attacker to potentially access a private artifact in a tree that would otherwise not be accessible to them. (CVE-2014-8111) All users of Red Hat JBoss Web Server 2.1.0 are advised to apply this update. The Red Hat JBoss Web Server process must be restarted for the update to take effect.
