CVE-2025-53448: Axiomthemes Rally LFI Vulnerability

CVE-2025-53448 Overview

CVE-2025-53448 is a Local File Inclusion (LFI) vulnerability affecting the Axiomthemes Rally WordPress theme. The vulnerability stems from improper control of filename parameters used in PHP include/require statements, allowing attackers to include arbitrary local files from the server. This vulnerability affects Rally theme versions through 1.1 and can be exploited remotely without authentication.

Critical Impact
Successful exploitation could allow attackers to read sensitive files, access configuration data, or potentially achieve remote code execution through log poisoning or other LFI-to-RCE techniques on WordPress installations using the vulnerable Rally theme.

Affected Products

Axiomthemes Rally WordPress Theme versions through 1.1
WordPress installations using the Rally theme

Technical Details for CVE-2025-53448

Vulnerability Analysis

This vulnerability is classified under CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program). The Rally WordPress theme fails to properly sanitize or validate user-supplied input before passing it to PHP include or require functions. This allows an attacker to manipulate file path parameters to include local files from the server's filesystem.

Local File Inclusion vulnerabilities in WordPress themes are particularly dangerous because they can expose sensitive configuration files such as wp-config.php, which contains database credentials and authentication keys. Additionally, LFI can potentially be escalated to Remote Code Execution through techniques such as log file poisoning, session file injection, or inclusion of uploaded files.

The network-based attack vector means that this vulnerability can be exploited remotely by any user who can send requests to the WordPress installation, without requiring any authentication or user interaction.

Root Cause

The root cause is insufficient input validation and sanitization in the Rally theme's PHP code. When the theme processes requests that include file paths or template names, it fails to properly validate these inputs before using them in include(), require(), include_once(), or require_once() statements. This allows path traversal sequences (such as ../) to be used to access files outside the intended directory structure.

Attack Vector

The vulnerability is exploited through the network attack vector. An attacker can craft malicious HTTP requests containing path traversal sequences to include arbitrary local files. The attack does not require authentication or any special privileges, though it requires some complexity in crafting the exploitation payload.

Typical exploitation involves manipulating URL parameters or POST data that are processed by the vulnerable theme code. By injecting sequences like ../../ along with target file paths, attackers can traverse out of the intended directory and access sensitive system files or WordPress configuration files.

Detection Methods for CVE-2025-53448

Indicators of Compromise

Unusual HTTP requests containing path traversal sequences such as ../, ..%2F, or URL-encoded variants targeting theme files
Web server access logs showing requests with file paths like /etc/passwd, wp-config.php, or other sensitive files in parameters
Unexpected file access patterns in application logs, particularly attempts to read files outside the theme directory
Evidence of log file poisoning attempts (malicious code in access logs or error logs)

Detection Strategies

Implement Web Application Firewall (WAF) rules to detect and block path traversal patterns in HTTP requests
Monitor web server access logs for requests containing .., %2e%2e, or similar traversal sequences
Deploy intrusion detection systems (IDS) with signatures for LFI attack patterns
Conduct regular security audits of WordPress installations to identify outdated or vulnerable themes

Monitoring Recommendations

Enable detailed logging for WordPress and the web server to capture full request URIs and parameters
Set up alerts for requests attempting to access files outside the web root directory
Monitor for unusual file read operations through endpoint detection solutions
Implement file integrity monitoring on critical WordPress files like wp-config.php

How to Mitigate CVE-2025-53448

Immediate Actions Required

Audit your WordPress installations to identify if the Rally theme version 1.1 or earlier is installed
Consider temporarily disabling or removing the Rally theme until a patched version is available
Implement Web Application Firewall rules to block path traversal attempts
Review web server logs for evidence of exploitation attempts
Restrict file system permissions to limit the impact of potential file inclusion attacks

Patch Information

As of the last update on 2026-01-20, administrators should check with Axiomthemes for updated versions of the Rally theme that address this vulnerability. Monitor the Patchstack advisory for updates regarding available patches.

Workarounds

Switch to an alternative WordPress theme that is not affected by this vulnerability
Implement strict input validation at the web server level using ModSecurity or similar WAF solutions
Use PHP open_basedir restrictions to limit file access to the WordPress directory structure
Configure web server rules to block requests containing path traversal sequences

bash

# Example ModSecurity rule to block path traversal attempts
SecRule REQUEST_URI|ARGS|ARGS_NAMES "@contains ../" \
    "id:1001,\
    phase:2,\
    deny,\
    status:403,\
    log,\
    msg:'Path Traversal Attack Detected',\
    tag:'LFI'"
