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 open redirect vulnerability. A remote unprivileged attacker may potentially redirect legitimate users to arbitrary web sites and conduct phishing attacks. The attacker could then steal the victims' credentials and silently authenticate them to the RSA Archer application without the victims realizing an attack occurred.

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Fake the Source of Data
    An adversary provides data under a falsified identity. The purpose of using the falsified identity may be to prevent traceability of the provided data or it might be an attempt by the adversary to assume the rights granted to another identity. One of the simplest forms of this attack would be the creation of an email message with a modified "From" field in order to appear that the message was sent from someone other than the actual sender. Results of the attack vary depending on the details of the attack, but common results include privilege escalation, obfuscation of other attacks, and data corruption/manipulation.

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)");
