Summary

IDE Xcode Server in Apple Xcode before 7.0 does not properly restrict access to repository e-mail lists, which allows remote attackers to obtain potentially sensitive build information in opportunistic circumstances by leveraging incorrect notification delivery.

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 Apple Xcode installed on the remote Mac OS X host is prior to 7.0. It is, therefore, affected by the multiple vulnerabilities : - A memory leak issue exists in file d1_srtp.c related to the DTLS SRTP extension handling and specially crafted handshake messages. An attacker can exploit this to cause denial of service condition. (CVE-2014-3513) - 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) - A memory leak issue exists in file t1_lib.c related to session ticket handling. An attacker can exploit this to cause denial of service condition. (CVE-2014-3567) - An error exists related to the build configuration process and the

  - A memory leak issue exists in file t1_lib.c related to
    session ticket handling. An attacker can exploit this to 
    cause denial of service condition. (CVE-2014-3567)

  - An error exists related to the build configuration
    process and the 'no-ssl3' build option that allows
    servers and clients to process insecure SSL 3.0
    handshake messages. (CVE-2014-3568)

  - A directory traversal vulnerability exists in send.js
    due to improper sanitization of user-supplied input.
    A remote, unauthenticated attacker can exploit this, via
    a specially crafted request, to access arbitrary files
    outside of the restricted path. (CVE-2014-6394)

  - A denial of service vulnerability exists in the
    mod_dav_svn and svnserve servers of Apache Subversion. A
    remote, unauthenticated attacker can exploit this, via a
    crafted combination of parameters, to cause the current
    process to abort through a failed assertion.
    (CVE-2015-0248)

  - A flaw exists in the mod_dav_svn server of Apache
    Subversion. A remote, authenticated attacker can exploit
    this, via a crafted HTTP request sequence, to spoof an
    'svn:author' property value. (CVE-2015-0251)

  - A flaw exists in the Apache HTTP Server due to the
    ap_some_auth_required() function in file request.c not
    properly handling Require directive associations. A
    remote, unauthenticated attacker can exploit this to
    bypass access restrictions, by leveraging a module that
    relies on the 2.2 API behavior. (CVE-2015-3185)

  - A flaw exists in the IDE Xcode server due to improper
    restriction of access to the repository email lists. A
    remote, unauthenticated attacker can exploit this to
    access sensitive build information, by leveraging
    incorrect notification delivery. (CVE-2015-5909)

  - A flaw exists in the IDE Xcode server due to the
    transmission of server information in cleartext. A
    remote, man-in-the-middle attacker can exploit this to
    access sensitive information. (CVE-2015-5910)");
