Foxit PDF Reader 3D Annotation Out-of-Bounds Memory Access Vulnerability

A memory corruption vulnerability exists in the 3D annotation handling of Foxit PDF Reader due to insufficient bounds checking when parsing PRC data. When opening a PDF file containing malformed or specially crafted PRC content, out-of-bounds memory access may occur, resulting in memory corruption.

Foxit PDF Reader Annotation Use-After-Free Remote Code Execution Vulnerability

A use-after-free vulnerability exists in the annotation handling of Foxit PDF Reader before 2025.2.1, 14.0.1, and 13.2.1 on Windows and MacOS. When opening a PDF containing specially crafted JavaScript, a pointer to memory that has already been freed may be accessed or dereferenced, potentially allowing a remote attacker to execute arbitrary code.

Foxit PDF Reader Update Service Incorrect Permission Assignment Local Privilege Escalation Vulnerability

A local privilege escalation vulnerability exists in the Foxit PDF Reader/Editor Update Service. During plugin installation, incorrect file system permissions are assigned to resources used by the update service. A local attacker with low privileges could modify or replace these resources, which are later executed by the service, resulting in execution of arbitrary code with SYSTEM privileges.

Foxit pdfonline.foxit.com Stored Cross-Site Scripting in eSign Predefined Text Feature

A stored cross-site scripting (XSS) vulnerability exists in pdfonline.foxit.com within the Predefined Text feature of the Foxit eSign section. A crafted payload can be stored via the Identity “First Name” field, which is later rendered into the DOM without proper sanitization. As a result, the injected script may execute when predefined text is used or when viewing document properties.

Foxit pdfonline.foxit.com Stored Cross-Site Scripting in Page Templates Feature

A stored cross-site scripting (XSS) vulnerability exists in pdfonline.foxit.com within the Page Templates feature. A crafted payload can be stored as the template name, which is later rendered into the DOM without proper sanitization. As a result, the injected script executes each time the affected PDF is loaded.

Foxit pdfonline.foxit.com Stored Cross-Site Scripting in Layer Import Functionality

A stored cross-site scripting (XSS) vulnerability exists in pdfonline.foxit.com within the Layer Import functionality. A crafted payload can be injected into the “Create new Layer” field during layer import and is later rendered into the DOM without proper sanitization. As a result, the injected script executes when the Layers panel is accessed.

Foxit pdfonline.foxit.com Stored Cross-Site Scripting in Portfolio SVG Handling

A stored cross-site scripting (XSS) vulnerability exists in the Portfolio feature of the Foxit PDF Editor cloud (pdfonline.foxit.com). User-supplied SVG files are not properly sanitized or validated before being inserted into the HTML structure. As a result, embedded HTML or JavaScript within a crafted SVG may execute whenever the Portfolio file list is rendered.

Foxit pdfonline.foxit.com Stored Cross-Site Scripting in Trusted Certificates Feature

A stored cross-site scripting (XSS) vulnerability exists in pdfonline.foxit.com within the Trusted Certificates feature. A crafted payload can be injected as the certificate name, which is later rendered into the DOM without proper sanitization. As a result, the injected script executes each time the Trusted Certificates view is loaded.

Foxit pdfonline.foxit.com Stored Cross-Site Scripting in Digital IDs Common Name Field

A stored cross-site scripting (XSS) vulnerability exists in the Digital IDs functionality of the Foxit PDF Editor Cloud (pdfonline.foxit.com). The application does not properly sanitize or encode the Common Name field of Digital IDs before inserting user-supplied content into the DOM. As a result, embedded HTML or JavaScript may execute whenever the Digital IDs dialog is accessed or when the affected PDF is loaded.

Foxit webplugins.foxit.com Stored Cross-Site Scripting via postMessage Vulnerability

A stored cross-site scripting (XSS) vulnerability exists in webplugins.foxit.com. A postMessage handler fails to validate the message origin and directly assigns externalPath to a script source, allowing an attacker to execute arbitrary JavaScript when a crafted postMessage is received.

A use-after-free vulnerability exists in the way Foxit Reader 2024.1.0.23997 handles a ComboBox widget. A specially crafted JavaScript code inside a malicious PDF document can trigger reuse of a previously freed object, which can lead to memory corruption and result in arbitrary code execution. An attacker needs to trick the user into opening the malicious file to trigger this vulnerability. Exploitation is also possible if a user visits a specially crafted, malicious site if the browser plugin extension is enabled.

A type confusion vulnerability vulnerability exists in the way Foxit Reader 2024.1.0.23997 handles a Lock object. A specially crafted Javascript code inside a malicious PDF document can trigger this vulnerability, which can lead to memory corruption and result in arbitrary code execution. An attacker needs to trick the user into opening the malicious file to trigger this vulnerability. Exploitation is also possible if a user visits a specially crafted, malicious site if the browser plugin extension is enabled.

A privilege escalation vulnerability exists in the Foxit Reader 2024.2.0.25138. The vulnerability occurs due to improper certification validation of the updater executable before executing it. A low privilege user can trigger the update action which can result in unexpected elevation of privilege.

The Portable Document Format (PDF) specification does not provide any information regarding the concrete procedure of how to validate signatures. Consequently, a Signature Wrapping vulnerability exists in multiple products. An attacker can use /ByteRange and xref manipulations that are not detected by the signature-validation logic. This affects Foxit Reader before 9.4 and PhantomPDF before 8.3.9 and 9.x before 9.4. It also affects eXpert PDF 12 Ultimate, Expert PDF Reader, Nitro Pro, Nitro Reader, PDF Architect 6, PDF Editor 6 Pro, PDF Experte 9 Ultimate, PDFelement6 Pro, PDF Studio Viewer 2018, PDF Studio Pro, PDF-XChange Editor and Viewer, Perfect PDF 10 Premium, Perfect PDF Reader, Soda PDF, and Soda PDF Desktop.

An issue was discovered in Foxit PDF Editor before 11.0.1 and PDF Reader before 11.0.1 on macOS. It mishandles missing dictionary entries, leading to a NULL pointer dereference, aka CNVD-C-2021-95204.

An issue was discovered in Foxit PDF Reader before 11.0.1 and PDF Editor before 11.0.1. It allows stack consumption during recursive processing of embedded XML nodes.

An issue was discovered in Foxit PDF Reader before 11.0.1 and PDF Editor before 11.0.1. It allows writing to arbitrary files via submitForm.

An issue was discovered in Foxit PDF Reader before 11.0.1 and PDF Editor before 11.0.1. It allows an out-of-bounds read via util.scand.

An issue was discovered in Foxit PDF Reader before 11.0.1 and PDF Editor before 11.0.1. It mishandles situations in which an array size (derived from a /Size entry) is smaller than the maximum indirect object number, and thus there is an attempted incorrect array access (leading to a NULL pointer dereference, or out-of-bounds read or write).

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit PDF Reader 11.0.0.49893. 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 handling of Annotation objects. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-14013.
