Summary

The SIP channel driver in Asterisk Open Source 1.8.x before 1.8.20.2, 10.x before 10.12.2, and 11.x before 11.2.2; Certified Asterisk 1.8.15 before 1.8.15-cert2; Asterisk Business Edition (BE) C.3.x before C.3.8.1; and Asterisk Digiumphones 10.x-digiumphones before 10.12.2-digiumphones exhibits different behavior for invalid INVITE, SUBSCRIBE, and REGISTER transactions depending on whether the user account exists, which allows remote attackers to enumerate account names by (1) reading HTTP status codes, (2) reading additional text in a 403 (aka Forbidden) response, or (3) observing whether certain retransmissions occur.

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 Asterisk Development Team has announced security releases for Certified Asterisk 1.8.15 and Asterisk 1.8, 10, and 11. The available security releases are released as versions 1.8.15-cert2, 1.8.20.2, 10.12.2, 10.12.2-digiumphones, and 11.2.2. These releases are available for immediate download at http://downloads.asterisk.org/pub/telephony/asterisk/releases The release of these versions resolve the following issues : - A possible buffer overflow during H.264 format negotiation. The format attribute resource for H.264 video performs an unsafe read against a media attribute when parsing the SDP. This vulnerability only affected Asterisk 11. - A denial of service exists in Asterisk

"The Asterisk Development Team has announced security releases for
Certified Asterisk 1.8.15 and Asterisk 1.8, 10, and 11. The available
security releases are released as versions 1.8.15-cert2, 1.8.20.2,
10.12.2, 10.12.2-digiumphones, and 11.2.2.

These releases are available for immediate download at
http://downloads.asterisk.org/pub/telephony/asterisk/releases

The release of these versions resolve the following issues :

  - A possible buffer overflow during H.264 format
    negotiation. The format attribute resource for H.264
    video performs an unsafe read against a media attribute
    when parsing the SDP.

    This vulnerability only affected Asterisk 11.

  - A denial of service exists in Asterisk's HTTP server.
    AST-2012-014, fixed in January of this year, contained a
    fix for Asterisk's HTTP server for a remotely-triggered
    crash. While the fix prevented the crash from being
    triggered, a denial of service vector still exists with
    that solution if an attacker sends one or more HTTP POST
    requests with very large Content-Length values.

    This vulnerability affects Certified Asterisk 1.8.15,
    Asterisk 1.8, 10, and 11

  - A potential username disclosure exists in the SIP
    channel driver. When authenticating a SIP request with
    alwaysauthreject enabled, allowguest disabled, and
    autocreatepeer disabled, Asterisk discloses whether a
    user exists for INVITE, SUBSCRIBE, and REGISTER
    transactions in multiple ways.

    This vulnerability affects Certified Asterisk 1.8.15,
    Asterisk 1.8, 10, and 11

These issues and their resolutions are described in the security
advisories.

Stack-based buffer overflow in res/res_format_attr_h264.c in Asterisk Open Source 11.x before 11.2.2 allows remote attackers to execute arbitrary code via a long sprop-parameter-sets H.264 media attribute in a SIP Session Description Protocol (SDP) header (CVE-2013-2685). main/http.c in the HTTP server in Asterisk Open Source 1.8.x before 1.8.20.2, 10.x before 10.12.2, and 11.x before 11.2.2; Certified Asterisk 1.8.15 before 1.8.15-cert2; and Asterisk Digiumphones 10.x-digiumphones before 10.12.2-digiumphones does not properly restrict Content-Length values, which allows remote attackers to conduct stack-consumption attacks and cause a denial of service (daemon crash) via a crafted HTTP POST request. NOTE: this vulnerability exists because of an incorrect fix for CVE-2012-5976 (CVE-2013-2686). The updated packages have upgraded to the 11.2.2 version which is not vulnerable to these issues

"Multiple vulnerablilities was identified and fixed in asterisk :

The SIP channel driver in Asterisk Open Source 1.8.x before 1.8.20.2,
10.x before 10.12.2, and 11.x before 11.2.2; Certified Asterisk 1.8.15
before 1.8.15-cert2; Asterisk Business Edition (BE) C.3.x before
C.3.8.1; and Asterisk Digiumphones 10.x-digiumphones before
10.12.2-digiumphones exhibits different behavior for invalid INVITE,
SUBSCRIBE, and REGISTER transactions depending on whether the user
account exists, which allows remote attackers to enumerate account
names by (1) reading HTTP status codes, (2) reading additional text in
a 403 (aka Forbidden) response, or (3) observing whether certain
retransmissions occur (CVE-2013-2264).

Stack-based buffer overflow in res/res_format_attr_h264.c in Asterisk
Open Source 11.x before 11.2.2 allows remote attackers to execute
arbitrary code via a long sprop-parameter-sets H.264 media attribute
in a SIP Session Description Protocol (SDP) header (CVE-2013-2685).

main/http.c in the HTTP server in Asterisk Open Source 1.8.x before
1.8.20.2, 10.x before 10.12.2, and 11.x before 11.2.2; Certified
Asterisk 1.8.15 before 1.8.15-cert2; and Asterisk Digiumphones
10.x-digiumphones before 10.12.2-digiumphones does not properly
restrict Content-Length values, which allows remote attackers to
conduct stack-consumption attacks and cause a denial of service
(daemon crash) via a crafted HTTP POST request. NOTE: this
vulnerability exists because of an incorrect fix for CVE-2012-5976
(CVE-2013-2686).

The updated packages have upgraded to the 11.2.2 version which is not
vulnerable to these issues"
