Summary

IBM BigFix Platform 9.2.0 through 9.2.14 and 9.5 through 9.5.9 discloses sensitive information to unauthorized users. The information can be used to mount further attacks on the system. IBM X-Force ID: 140757.

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.

descriptionAccording to its self-reported version, the IBM BigFix Platform application running on the remote host is 9.2.x prior to 9.2.15, or 9.5.x prior to 9.5.10. It is, therefore, affected by multiple vulnerabilities : - IBM BigFix Platform is vulnerable to HTTP response splitting attacks, caused by improper validation of user-supplied input. A remote attacker could exploit this vulnerability to inject arbitrary HTTP headers and cause the server to return a split response, once the URL is clicked. This would allow the attacker to perform further attacks, such as Web cache poisoning or cross-site scripting, and possibly obtain sensitive information. (CVE-2018-1474) - IBM BigFix Platform does not renew a session variable after a successful authentication which could lead to session fixation/hijacking vulnerability. This could force a user to utilize a cookie that may be known to an attacker. (CVE-2018-1485) - OpenSSL is vulnerable to a denial of service. By sending specially crafted ASN.1 data with a recursive definition, a remote attacker could exploit this vulnerability to consume excessive stack memory. (CVE-2018-0739) In addition, IBM BigFix Platform is also affected by several additional vulnerabilities including multiple information disclosure vulnerabilities, a clickjacking vulnerability, multiple sensitive cookie weakened security vulnerabilities, and a session hijacking vulnerability. IBM BigFix Platform was formerly known as Tivoli Endpoint Manager, IBM Endpoint Manager, and IBM BigFix Endpoint Manager. Note that Nessus has not tested for these issues but has instead relied only on the application
