Summary

EMC RSA Archer 5.4.1.3, 5.5.3.1, 5.5.2.3, 5.5.2, 5.5.1.3.1, 5.5.1.1 is affected by an information exposure through an error message vulnerability. A remote low privileged attacker may potentially exploit this vulnerability to use information disclosed in an error message to launch another more focused attack.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (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.

descriptionThe version of EMC RSA Archer running on the remote web server is prior to 6.2.0.2. It is, therefore, affected by multiple vulnerabilities : - A cross-site request forgery (XSRF) vulnerability exists when handling HTTP requests due to a failure to require multiple steps, explicit confirmation, or a unique token when performing sensitive actions. An authenticated, remote attacker can exploit this, by convincing a user to follow a specially crafted link, to execute unauthorized actions on behalf of the user with the user

"The version of EMC RSA Archer running on the remote web server is
prior to 6.2.0.2. It is, therefore, affected by multiple
vulnerabilities :

  - A cross-site request forgery (XSRF) vulnerability exists
    when handling HTTP requests due to a failure to require
    multiple steps, explicit confirmation, or a unique token
    when performing sensitive actions. An authenticated,
    remote attacker can exploit this, by convincing a user
    to follow a specially crafted link, to execute
    unauthorized actions on behalf of the user with the
    user's level of privileges. (CVE-2017-4998)

  - An authorization bypass vulnerability exists in
    Discussion Forum Messages component due to improper
    handling of input passed via user-controlled keys. An
    authenticated, remote attacker can exploit this to gain
    elevated privileges and view other users' discussion
    forum messages. (CVE-2017-4999)

  - Multiple information disclosure vulnerabilities exist in
    error messages that allow an authenticated, remote
    attacker to gain potentially sensitive information.
    (CVE-2017-5000, CVE-2017-5001)

  - A cross-side redirection vulnerability exists due to
    improper validation of user-supplied input before
    returning it to users. An unauthenticated, remote
    attacker can exploit this, via a specially crafted link,
    to redirect an unsuspecting user from the intended
    trusted website to an arbitrary website of the
    attacker's choosing, which can then be used to conduct
    further attacks. (CVE-2017-5002)");
