Vulnerabilidades

The Hide My WP Ghost – Security & Firewall plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the URL in all versions up to, and including, 5.3.01 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in…

An issue was discovered in psi/zfile.c in Artifex Ghostscript before 10.04.0. Out-of-bounds data access in filenameforall can lead to arbitrary code execution.

An issue was discovered in psi/zcolor.c in Artifex Ghostscript before 10.04.0. There is an out-of-bounds read when reading color in Indexed color space.

An issue was discovered in decode_utf8 in base/gp_utf8.c in Artifex Ghostscript before 10.04.0. Overlong UTF-8 encoding leads to possible ../ directory traversal.

An issue was discovered in base/gsdevice.c in Artifex Ghostscript before 10.04.0. An integer overflow when parsing the filename format string (for the output filename) results in path truncation, and possible path traversal and code execution.

An issue was discovered in pdf/pdf_xref.c in Artifex Ghostscript before 10.04.0. There is a buffer overflow during handling of a PDF XRef stream (related to W array values).

An issue was discovered in psi/zcolor.c in Artifex Ghostscript before 10.04.0. An unchecked Implementation pointer in Pattern color space could lead to arbitrary code execution.

Ghost is a Node.js content management system. Improper authentication on some endpoints used for member actions would allow an attacker to perform member-only actions, and read member information. This security vulnerability is present in Ghost v4.46.0-v5.89.4. v5.89.5 contains a fix for this issue.

The Hide My WP Ghost WordPress plugin before 5.2.02 does not prevent redirects to the login page via the auth_redirect WordPress function, allowing an unauthenticated visitor to access the hidden login page.

An issue was discovered in Artifex Ghostscript before 10.03.1. contrib/opvp/gdevopvp.c allows arbitrary code execution via a custom Driver library, exploitable via a crafted PostScript document. This occurs because the Driver parameter for opvp (and oprp) devices can have an arbitrary name for a dynamic library; this…

An issue was discovered in Artifex Ghostscript before 10.03.1. There is path traversal (via a crafted PostScript document) to arbitrary files if the current directory is in the permitted paths. For example, there can be a transformation of ../../foo to ./../../foo and this will grant access if ./ is permitted.

An issue was discovered in Artifex Ghostscript before 10.03.1. Path traversal and command execution can occur (via a crafted PostScript document) because of path reduction in base/gpmisc.c. For example, restrictions on use of %pipe% can be bypassed via the aa/../%pipe%command# output filename.

Artifex Ghostscript before 10.03.1, when Tesseract is used for OCR, has a directory traversal issue that allows arbitrary file reading (and writing of error messages to arbitrary files) via OCRLanguage. For example, exploitation can use debug_file /tmp/out and user_patterns_file /etc/passwd.

Artifex Ghostscript before 10.03.1 allows memory corruption, and SAFER sandbox bypass, via format string injection with a uniprint device.

Artifex Ghostscript before 10.03.0 sometimes has a stack-based buffer overflow via the CIDFSubstPath and CIDFSubstFont parameters.

Artifex Ghostscript before 10.03.0 has a heap-based overflow when PDFPassword (e.g., for runpdf) has a \000 byte in the middle.

Artifex Ghostscript before 10.03.0 has a heap-based pointer disclosure (observable in a constructed BaseFont name) in the function pdf_base_font_alloc.

Artifex Ghostscript before 10.03.0 has a stack-based buffer overflow in the pdfi_apply_filter() function via a long PDF filter name.

Ghost through 5.85.1 allows remote attackers to bypass an authentication rate-limit protection mechanism by using many X-Forwarded-For headers with different values. NOTE: the vendor's position is that Ghost should be installed with a reverse proxy that allows only trusted X-Forwarded-For headers.

An issue was discovered in Kape CyberGhostVPN 8.4.3.12823 on Windows. After a successful logout, user credentials remain in memory while the process is still open, and can be obtained by dumping the process memory and parsing it.

Improper Restriction of Excessive Authentication Attempts vulnerability in WPPlugins – WordPress Security Plugins Hide My WP Ghost allows Functionality Bypass.This issue affects Hide My WP Ghost: from n/a through 5.0.25.

Ghost before 5.82.0 allows CSV Injection during a member CSV export.

Insertion of Sensitive Information into Log File vulnerability in Ghost Foundation Ghost.This issue affects Ghost: from n/a through 1.4.0.

An issue was discovered in Artifex Ghostscript before 10.03.1. psi/zmisc1.c, when SAFER mode is used, allows eexec seeds other than the Type 1 standard.

Ghost through 5.76.0 allows stored XSS, and resultant privilege escalation in which a contributor can take over any account, via an SVG profile picture that contains JavaScript code to interact with the API on localhost TCP port 3001. NOTE: The discoverer reports that "The vendor does not view this as a valid vector."
