ID CVE-2016-4053
Summary Squid 3.x before 3.5.17 and 4.x before 4.0.9 allow remote attackers to obtain sensitive stack layout information via crafted Edge Side Includes (ESI) responses, related to incorrect use of assert and compiler optimization.

Exploitability:
CWE CWE-119
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.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.
  • Overflow Binary Resource File
    An attack of this type exploits a buffer overflow vulnerability in the handling of binary resources. Binary resources may include music files like MP3, image files like JPEG files, and any other binary file. These attacks may pass unnoticed to the client machine through normal usage of files, such as a browser loading a seemingly innocent JPEG file. This can allow the attacker access to the execution stack and execute arbitrary code in the target process. This attack pattern is a variant of standard buffer overflow attacks using an unexpected vector (binary files) to wrap its attack and open up a new attack vector. The attacker is required to either directly serve the binary content to the victim, or place it in a locale like a MP3 sharing application, for the victim to download. The attacker then is notified upon the download or otherwise locates the vulnerability opened up by the buffer overflow.
  • Buffer Overflow via Symbolic Links
    This type of attack leverages the use of symbolic links to cause buffer overflows. An attacker can try to create or manipulate a symbolic link file such that its contents result in out of bounds data. When the target software processes the symbolic link file, it could potentially overflow internal buffers with insufficient bounds checking.
  • Overflow Variables and Tags
    This type of attack leverages the use of tags or variables from a formatted configuration data to cause buffer overflow. The attacker crafts a malicious HTML page or configuration file that includes oversized strings, thus causing an overflow.
  • Buffer Overflow via Parameter Expansion
    In this attack, the target software is given input that the attacker knows will be modified and expanded in size during processing. This attack relies on the target software failing to anticipate that the expanded data may exceed some internal limit, thereby creating a buffer overflow.
  • Buffer Overflow in an API Call
    This attack targets libraries or shared code modules which are vulnerable to buffer overflow attacks. An attacker who has access to an API may try to embed malicious code in the API function call and exploit a buffer overflow vulnerability in the function's implementation. All clients that make use of the code library thus become vulnerable by association. This has a very broad effect on security across a system, usually affecting more than one software process.
  • Buffer Overflow in Local Command-Line Utilities
    This attack targets command-line utilities available in a number of shells. An attacker can leverage a vulnerability found in a command-line utility to escalate privilege to root.

    description According to its banner, the version of Squid running on the remote host is 3.x prior to 3.5.17 or 4.x prior to 4.0.9. It is, therefore, affected by multiple vulnerabilities : - An assertion fault exists in file esi/Esi.cc that is triggered when handling ESI responses. An unauthenticated, remote attacker can exploit this, via an HTTP server that uses specially crafted Edge Side Includes (ESI), to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-4052) - A flaw exists in file esi/Esi.cc due to improper validation of user-supplied input when handling ESI responses. An unauthenticated, remote attacker can exploit this, via specially crafted ESI responses, to disclose sensitive stack layout information. (CVE-2016-4053) - A buffer overflow condition exists in file esi/Esi.cc due to improper validation of user-supplied input when handling ESI responses. An unauthenticated, remote attacker can exploit this, via specially crafted ESI responses, to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-4054) Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number. Furthermore, the patch released to address these issues does not update the version given in the banner. If the patch has been applied properly, and the service has been restarted, then consider this to be a false positive.

    description Several security issues have been discovered in the Squid caching proxy. CVE-2016-4051 CESG and Yuriy M. Kaminskiy discovered that Squid cachemgr.cgi was vulnerable to a buffer overflow when processing remotely supplied inputs relayed through Squid. CVE-2016-4052 CESG discovered that a buffer overflow made Squid vulnerable to a Denial of Service (DoS) attack when processing ESI responses. CVE-2016-4053 CESG found that Squid was vulnerable to public information disclosure of the server stack layout when processing ESI responses. CVE-2016-4054 CESG discovered that Squid was vulnerable to remote code execution when processing ESI responses. CVE-2016-4554 Jianjun Chen found that Squid was vulnerable to a header smuggling attack that could lead to cache poisoning and to bypass of same-origin security policy in Squid and some client browsers. CVE-2016-4555 and CVE-2016-4556 'bfek-18' and '@vftable' found that Squid was vulnerable to a Denial of Service (DoS) attack when processing ESI responses, due to incorrect pointer handling and reference counting. For Debian 7 'Wheezy', these issues have been fixed in squid3 version 3.1.20-2.2+deb7u5. We recommend you to upgrade your squid3 packages.

    description Squid security advisory 2016:5 reports : Due to incorrect buffer management Squid cachemgr.cgi tool is vulnerable to a buffer overflow when processing remotely supplied inputs relayed to it from Squid. This problem allows any client to seed the Squid manager reports with data that will cause a buffer overflow when processed by the cachemgr.cgi tool. However, this does require manual administrator actions to take place. Which greatly reduces the impact and possible uses. Squid security advisory 2016:6 reports : Due to buffer overflow issues Squid is vulnerable to a denial of service attack when processing ESI responses. Due to incorrect input validation Squid is vulnerable to public information disclosure of the server stack layout when processing ESI responses. Due to incorrect input validation and buffer overflow Squid is vulnerable to remote code execution when processing ESI responses. These problems allow ESI components to be used to perform a denial of service attack on the Squid service and all other services on the same machine. Under certain build conditions these problems allow remote clients to view large sections of the server memory. However, the bugs are exploitable only if you have built and configured the ESI features to be used by a reverse-proxy and if the ESI components being processed by Squid can be controlled by an attacker.
