Vulnerability Details

CVE-ID: CVE-2015-10137

Affected Software: The Website Contact Form With File Upload plugin for WordPress

Affected Versions: Versions up to and including an unspecified version are affected. See vendor advisory for specific affected versions.

Vulnerability: The vulnerability is an Unrestricted File Upload, stemming from a lack of proper file type validation within the upload_file() function. An unauthenticated remote attacker can craft a request to the contact form's file upload functionality and submit a file with a malicious extension (e.g., .php, .phtml). Because the backend code does not verify that the uploaded file is a benign type (like an image or document), the malicious script is saved to a web-accessible directory on the server. The attacker can then execute the script by navigating to its URL, granting them the ability to run arbitrary code on the server with the privileges of the web service account.

Business Impact

This vulnerability is rated as critical severity with a CVSS score of 9.8. Exploitation can lead to a full compromise of the web server, posing a severe risk to the organization. Potential consequences include the theft of sensitive data stored on the website (such as customer information, user credentials, and proprietary business data), reputational damage from website defacement, and financial loss from business disruption or regulatory fines. Furthermore, a compromised server can be used as a pivot point to attack other internal network resources or be leveraged in botnets for broader malicious campaigns.

Remediation Plan

Immediate Action: Immediately update The Website Contact Form With File Upload plugin for WordPress to the latest version, which contains a patch for this vulnerability. After updating, verify that the patch has been successfully applied and the site is functioning as expected.

Proactive Monitoring: System administrators should actively monitor for signs of compromise. Review web server access logs for unusual POST requests to the contact form's endpoint, followed by GET requests to non-image files (e.g., files with .php extensions) in the WordPress uploads directory. Implement file integrity monitoring to detect the creation of unexpected or malicious files in web-accessible directories.

Compensating Controls: If immediate patching is not feasible, the following controls can reduce risk:

• Disable and deactivate the vulnerable plugin until it can be safely updated.
• Implement a Web Application Firewall (WAF) with rules designed to inspect file uploads and block files with executable extensions.

Description Summary:
XML::Parser for Perl contains an off-by-one heap buffer overflow in the st_serial_stack function. Attackers can trigger this by providing XML files with deeply nested elements to cause a crash.

Executive Summary:
A critical heap buffer overflow in the Perl XML::Parser module allows unauthenticated attackers to cause a denial-of-service or potentially execute arbitrary code via specially crafted XML files.

Vulnerability Details

CVE-ID: CVE-2006-10003

Affected Software: Perl XML::Parser

Affected Versions: Versions through 2.47

Vulnerability: This vulnerability is a heap-based buffer overflow resulting from an off-by-one error in the st_serial_stack function. An unauthenticated attacker can exploit this flaw by submitting an XML file with extremely deep element nesting, which bypasses stack expansion checks and writes data outside the allocated buffer.

Business Impact

A successful exploit of this vulnerability could lead to immediate application instability or a complete system crash, resulting in significant service downtime. Given the CVSS score of 9.8, the flaw also carries a theoretical risk of remote code execution, which would allow an attacker to compromise the integrity of the host server and access sensitive data. Organizations relying on legacy Perl environments for XML processing are at the highest risk.

Remediation Plan

Immediate Action: Update the XML::Parser module to the latest available version (2.48 or higher) via CPAN or the relevant system package manager.

Proactive Monitoring: Implement monitoring for unusual application crashes or segmentation faults specifically occurring during XML parsing tasks.

Compensating Controls: Deploy a Web Application Firewall (WAF) or an XML Gateway to enforce maximum nesting depth limits on all incoming XML payloads.

Exploitation Status

Public Exploit Available: No

Analyst Notes: As of Mar 19, 2026, there is no public information indicating active exploitation of this vulnerability. However, due to the nature of the flaw and its presence in a widely used library, the potential for exploitation is high if legacy systems remain unpatched.

Analyst Recommendation

The severity of this heap overflow necessitates immediate remediation, especially for high-availability systems. Administrators should prioritize updating the Perl XML::Parser library across all production and development environments. If patching is not immediately feasible, strict input validation on XML depth must be enforced at the network perimeter.
