Summary

Foxit Reader 2.3 before Build 3902 and 3.0 before Build 1506, including 1120 and 1301, does not require user confirmation before performing dangerous actions defined in a PDF file, which allows remote attackers to execute arbitrary programs and have unspecified other impact via a crafted file, as demonstrated by the "Open/Execute a file" action.

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.
  • 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.

Metasploit

descriptionThis module exploits an authorization bypass vulnerability in Foxit Reader build 1120. When an attacker creates a specially crafted pdf file containing an Open/Execute action, arbitrary commands can be executed without confirmation from the victim.

descriptionThe version of Foxit Reader installed on the remote Windows host is 2.x prior to 2.3 Build 3902 or 3.x prior to 3.0 Build 1506. It is, therefore, affected by multiple vulnerabilities : - An uninitialized memory dereference flaw exists due to improper handling of a JBIG2 symbol dictionary segment with zero new symbols. An unauthenticated, remote attacker can exploit this, via a crafted PDF file, to execute arbitrary code. (CVE-2009-0191) - A flaw exists due to a failure to require user authorization before preforming dangerous actions defined in a PDF file. An unauthenticated, remote attacker can exploit this, via a crafted PDF file, to execute arbitrary commands. (CVE-2009-0836) - A stack-based buffer overflow condition exists due to improper sanitization of user-supplied input. An unauthenticated, remote attacker can exploit this to execute arbitrary code via a crafted PDF file having a long relative or absolute path in a filename argument in an action. Note that this issue only affects version 3.x. (CVE-2009-0837)
