NONE Summary
This vulnerability allows remote attackers to disclose sensitive information on vulnerable installations of Foxit Reader 8.3.0.14878. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of PDF files. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated object. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of the current process. Was ZDI-CAN-4738.

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.

NASL family Windows NASL id FOXIT_PHANTOM_8_3_1.NASL description According to its version, the Foxit PhantomPDF application (formally known as Phantom) installed on the remote Windows host is prior to 8.3.1. It is, therefore, affected by multiple vulnerabilities : - A use-after-free error exists in the AFParseDateEx() function. An unauthenticated, remote attacker can exploit this, by convincing a user to open a specially crafted PDF document, to dereference already freed memory and execute arbitrary code. (CVE-2017-10941) - Multiple out-of-bounds read errors exist that are triggered when handling specially crafted PDF files. An unauthenticated, remote attacker can exploit these to disclose sensitive information. (CVE-2017-10942, CVE-2017-10943) - An out-of-bounds read error exists due to improper parsing of ObjStm objects. An unauthenticated, remote attacker can exploit this to disclose sensitive information. (CVE-2017-10944) - A use-after-free error exists in the app.alert() function. An unauthenticated, remote attacker can exploit this, by convincing a user to open a specially crafted PDF document, to dereference already freed memory and execute arbitrary code. (CVE-2017-10945) - A use-after-free error exists in the setItem() function. An unauthenticated, remote attacker can exploit this, by convincing a user to open a specially crafted PDF document, to dereference already freed memory and execute arbitrary code. (CVE-2017-10946) - A use-after-free error exists in the print() function. An unauthenticated, remote attacker can exploit this, by convincing a user to open a specially crafted PDF document, to dereference already freed memory and execute arbitrary code. (CVE-2017-10947) - A use-after-free error exists in the app.execMenuItem() function. An unauthenticated, remote attacker can exploit this, by convincing a user to open a specially crafted PDF document, to dereference already freed memory and execute arbitrary code. (CVE-2017-10948) - An unspecified arbitrary write flaw exists. An unauthenticated, remote attacker can exploit this, by convincing a user to open a specially crafted PDF document, to execute arbitrary code. (CVE-2017-10994) - A NULL pointer dereference flaw exists that allows an unauthenticated, remote attacker to cause the application to crash, resulting in a denial of service condition. - A security bypass vulnerability exists in the Trust Manager due to a failure to honor the restriction of JavaScript actions. An unauthenticated, remote attacker can exploit this, by convincing a user to open a specially crafted PDF document, to execute arbitrary JavaScript functions. - An unspecified flaw exists that is triggered by the use of uninitialized data. An unauthenticated, remote attacker can exploit this to cause a denial of service condition. last seen 2020-04-30 modified 2017-07-13 plugin id 101523 published 2017-07-13 reporter This script is Copyright (C) 2017-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/101523 title Foxit PhantomPDF < 8.3.1 Multiple Vulnerabilities code # # (C) Tenable Network Security, Inc. # include("compat.inc"); if (description) { script_id(101523); script_version("1.9"); script_set_attribute(attribute:"plugin_modification_date", value:"2020/04/27"); script_cve_id( "CVE-2017-10941", "CVE-2017-10942", "CVE-2017-10943", "CVE-2017-10944", "CVE-2017-10945", "CVE-2017-10946", "CVE-2017-10947", "CVE-2017-10948", "CVE-2017-10994" ); script_bugtraq_id(99499); script_name(english:"Foxit PhantomPDF < 8.3.1 Multiple Vulnerabilities"); script_summary(english:"Checks the version of Foxit PhantomPDF."); script_set_attribute(attribute:"synopsis", value: "A PDF toolkit installed on the remote Windows host is affected by multiple vulnerabilities."); script_set_attribute(attribute:"description", value: "According to its version, the Foxit PhantomPDF application (formally known as Phantom) installed on the remote Windows host is prior to 8.3.1.
