Adobe BlazeDS, as used in ColdFusion 10 before Update 18 and 11 before Update 7 and LiveCycle Data Services 3.0.x before, 3.1.x before, 4.5.x before, 4.6.2.x before, and 4.7.x before, allows remote attackers to send HTTP traffic to intranet servers via a crafted XML document, related to a Server-Side Request Forgery (SSRF) issue.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Server Side Include (SSI) Injection
    An attacker can use Server Side Include (SSI) Injection to send code to a web application that then gets executed by the web server. Doing so enables the attacker to achieve similar results to Cross Site Scripting, viz., arbitrary code execution and information disclosure, albeit on a more limited scale, since the SSI directives are nowhere near as powerful as a full-fledged scripting language. Nonetheless, the attacker can conveniently gain access to sensitive files, such as password files, and execute shell commands.
  • Cross Zone Scripting
    An attacker is able to cause a victim to load content into their web-browser that bypasses security zone controls and gain access to increased privileges to execute scripting code or other web objects such as unsigned ActiveX controls or applets. This is a privilege elevation attack targeted at zone-based web-browser security. In a zone-based model, pages belong to one of a set of zones corresponding to the level of privilege assigned to that page. Pages in an untrusted zone would have a lesser level of access to the system and/or be restricted in the types of executable content it was allowed to invoke. In a cross-zone scripting attack, a page that should be assigned to a less privileged zone is granted the privileges of a more trusted zone. This can be accomplished by exploiting bugs in the browser, exploiting incorrect configuration in the zone controls, through a cross-site scripting attack that causes the attackers' content to be treated as coming from a more trusted page, or by leveraging some piece of system functionality that is accessible from both the trusted and less trusted zone. This attack differs from "Restful Privilege Escalation" in that the latter correlates to the inadequate securing of RESTful access methods (such as HTTP DELETE) on the server, while cross-zone scripting attacks the concept of security zones as implemented by a browser.
  • Cross Site Scripting through Log Files
    An attacker may leverage a system weakness where logs are susceptible to log injection to insert scripts into the system's logs. If these logs are later viewed by an administrator through a thin administrative interface and the log data is not properly HTML encoded before being written to the page, the attackers' scripts stored in the log will be executed in the administrative interface with potentially serious consequences. This attack pattern is really a combination of two other attack patterns: log injection and stored cross site scripting.
  • Command Line Execution through SQL Injection
    An attacker uses standard SQL injection methods to inject data into the command line for execution. This could be done directly through misuse of directives such as MSSQL_xp_cmdshell or indirectly through injection of data into the database that would be interpreted as shell commands. Sometime later, an unscrupulous backend application (or could be part of the functionality of the same application) fetches the injected data stored in the database and uses this data as command line arguments without performing proper validation. The malicious data escapes that data plane by spawning new commands to be executed on the host.

    descriptionThe VMware vCenter Server installed on the remote host is affected by the following vulnerabilities : - An XML external entity (XXE) injection flaw exists in Flex BlazeDS in the file flex-messaging-core.jar due to an incorrectly configured XML parser accepting XML external entities from untrusted sources. A remote attacker can exploit this, via a specially crafted AMF message containing an XML external entity declaration in conjunction with an entity reference, to read arbitrary files and thus gain access to potentially sensitive information. (CVE-2015-3269) - A server-side request forgery (SSRF) vulnerability exists in Flex BlazeDS. A remote attacker can exploit this, via a crafted XML document, to direct HTTP traffic to intranet servers, thus bypassing access restrictions and allowing further host-based attacks to be conducted. (CVE-2015-5255)

    descriptionThe VMware Horizon View installed on the remote Windows host is version 5.x prior to 5.3.4 or version 6.x prior to 6.1. It is, therefore, affected by the following vulnerabilities : - A man-in-the-middle (MitM) information disclosure vulnerability, known as POODLE, exists due to the way SSL 3.0 handles padding bytes when decrypting messages encrypted using block ciphers in cipher block chaining (CBC) mode. A MitM attacker can decrypt a selected byte of a cipher text in as few as 256 tries if they are able to force a victim application to repeatedly send the same data over newly created SSL 3.0 connections. (CVE-2014-3566) - An XML external entity (XXE) injection vulnerability exists in the included Flex BlazeDS component due to an incorrect configuration of the XML parser that allows external XML entities to be accepted from untrusted sources. An unauthenticated, remote attacker can exploit this vulnerability, via a via a crafted AMF message, to gain access to sensitive information. (CVE-2015-3269) - A flaw exists in the bundled Adobe ColdFusion and LiveCycle Data Services components related to request handling between a user and the server. A remote attacker can exploit this, via a specially crafted request, to bypass access restrictions (e.g. host or network ACLs), conduct port scanning of internal networks, enumerate internal hosts, or possibly invoke additional protocols (e.g. Gopher, TFTP). (CVE-2015-5255) Additionally, unspecified vulnerabilities also exist in the following bundled Java components : - 2D (CVE-2014-6585, CVE-2014-6591) - Deployment (CVE-2015-0403, CVE-2015-0406) - Hotspot (CVE-2014-6601, CVE-2015-0383, CVE-2015-0395, CVE-2015-0437) - Installation (CVE-2015-0421) - JAX-WS (CVE-2015-0412) - JSSE (CVE-2014-6593) - Libraries (CVE-2014-6549, CVE-2014-6587, CVE-2015-0400) - RMI (CVE-2015-0408) - Security (CVE-2015-0410) - Serviceability (CVE-2015-0413) - Swing (CVE-2015-0407)
