Vulnerabilities > CVE-2019-13318 - Use of Externally-Controlled Format String vulnerability in Foxitsoftware Reader
Summary
This vulnerability allows remote attackers to disclose sensitive information on affected installations of Foxit Reader 9.5.0.20723. 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 processing of the util.printf Javascript method. The application processes the %p parameter in the format string, allowing heap addresses to be returned to the script. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of the current process. Was ZDI-CAN-8544.
Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Format String Injection An attacker includes formatting characters in a string input field on the target application. Most applications assume that users will provide static text and may respond unpredictably to the presence of formatting character. For example, in certain functions of the C programming languages such as printf, the formatting character %s will print the contents of a memory location expecting this location to identify a string and the formatting character %n prints the number of DWORD written in the memory. An attacker can use this to read or write to memory locations or files, or simply to manipulate the value of the resulting text in unexpected ways. Reading or writing memory may result in program crashes and writing memory could result in the execution of arbitrary code if the attacker can write to the program stack.
- String Format Overflow in syslog() This attack targets the format string vulnerabilities in the syslog() function. An attacker would typically inject malicious input in the format string parameter of the syslog function. This is a common problem, and many public vulnerabilities and associated exploits have been posted.

NASL family Windows NASL id FOXIT_PHANTOM_8_3_11.NASL description According to its version, the Foxit PhantomPDF application (formally known as Phantom) installed on the remote Windows host is prior to 8.3.11. It is, therefore affected by multiple vulnerabilities: - An uninitialized pointer flaw exists when calling xfa.event.rest XFA JavaScript that can cause the application to crash the application. - A NULL pointer dereference flaw exists when calling certain XFA JavaScript and can cause the application to crash. (CVE-2019-14212) - An array-indexing error exists during XFA layout when the original node object contains one more contentArea object than that in XFA layout and cause the application to crash. - A use-after-free remote code execution vulnerability exists when processing AcroForms because an additional event is triggered to delete ListBox and ComboBox Field when trying to delete the items in ListBox and ComboBox Field by calling the deleteItemAt method. (CVE-2019-6774) - A heap buffer overflow vulnerability exists because the maximum length in For loop is not updated correctly when all the Field APs are updated after executing Field related JavaScript, and this can cause the application to crash. - An unspecified vulnerability exists where the repeated release of signature dictionary during CSG_SignatureF and CPDF_Document destruction can cause the application to crash.(CVE-2019-14213) - An unspecified vulnerability exists due to the lack of proper validation of the existence of an object prior to performing operations on the object when executing JavaScript. This can cause the application to crash. (CVE-2019-14211) - A use-after-free remote code execution vulnerability exists because Field object is deleted during parameter calculation when setting certain attributes in Field object using JavaScript.

This can cause the application to crash. (CVE-2019-14207) - A NULL pointer dereference flaw exists when parsing certain Epub files. This occurs because a null string is written to FXSYS_wcslen which does not support null strings. This can cause the application to crash. - A use-after-free remote code execution vulnerability exists due to the use of Field objects or control after they have been deleted or released which can cause the application to crash. (CVE-2019-13319) - An information disclosure vulnerability exists when calling util.printf JavaScript as the actual memory address of any variable available to the JavaScript can be extracted. (CVE-2019-13318) - An out-of-bounds write vulnerability exists when users use the application in Internet Explorer because the input argument exceed the array length.
