CVE-2024-31259: SearchIQ Information Disclosure Flaw

CVE-2024-31259 Overview

CVE-2024-31259 is an information disclosure vulnerability in the SearchIQ plugin for WordPress. The flaw is classified as Insertion of Sensitive Information into Log File [CWE-532]. It affects all versions of SearchIQ from an unspecified earlier release through version 4.5.

The plugin writes sensitive data into log files that are accessible without authentication. A remote attacker can retrieve these logs over the network and extract data exposed during normal plugin operation. The vulnerability impacts confidentiality only; integrity and availability are not affected.

Critical Impact
Unauthenticated remote attackers can read sensitive information written to plugin log files on affected WordPress sites running SearchIQ through version 4.5.

Affected Products

SearchIQ WordPress plugin versions up to and including 4.5
WordPress installations with the SearchIQ plugin enabled
Sites exposing the plugin log file path to unauthenticated HTTP requests

Technical Details for CVE-2024-31259

Vulnerability Analysis

The SearchIQ plugin records operational data to a log file stored within the plugin's directory structure on the web server. The log entries contain sensitive information generated during search operations and plugin activity. Because the file resides in a web-accessible path and is not protected by access controls, a remote client can request it directly over HTTP and retrieve its contents.

The issue is categorized under [CWE-532] Insertion of Sensitive Information into Log File. Disclosure of this information can support reconnaissance and follow-on attacks against the affected WordPress site or its users.

Root Cause

The root cause is twofold. First, the plugin writes sensitive runtime data into a log file rather than restricting that data to a protected store. Second, the log file is placed in a location reachable through the web server without authentication or authorization checks. No .htaccess rule, deny directive, or randomized filename prevents direct retrieval.

Attack Vector

The attack vector is network-based and requires no authentication or user interaction. An attacker enumerates the SearchIQ plugin path under /wp-content/plugins/ and requests the known log filename. The server returns the log contents, which the attacker parses for sensitive values. Automated scanners can perform this retrieval at scale across WordPress sites.

No public proof-of-concept exploit, exploit database entry, or CISA KEV listing is associated with this CVE at the time of publication. See the Patchstack Vulnerability Report for technical details.

Detection Methods for CVE-2024-31259

Indicators of Compromise

HTTP GET requests targeting paths under /wp-content/plugins/searchiq/ that reference .log or .txt files
Repeated unauthenticated requests from a single source enumerating plugin file paths
Web server access logs showing 200 OK responses to direct requests for plugin log files

Detection Strategies

Review WordPress web server access logs for successful retrieval of files within the SearchIQ plugin directory by external clients
Inspect the SearchIQ plugin directory on the filesystem for log files and assess whether their contents include user input, identifiers, or other sensitive fields
Run an authenticated vulnerability scan against the WordPress site that includes plugin version checks for SearchIQ 4.5 and earlier

Monitoring Recommendations

Alert on direct requests to files under /wp-content/plugins/ that return non-PHP content types such as text/plain
Monitor outbound traffic from web crawlers and scanners that probe known WordPress plugin paths
Track the installed version of SearchIQ across managed WordPress instances and flag versions at or below 4.5

How to Mitigate CVE-2024-31259

Immediate Actions Required

Identify all WordPress installations running the SearchIQ plugin and confirm the installed version
Update SearchIQ to a version newer than 4.5 once the vendor publishes a fixed release
Delete any existing log files generated by the plugin after reviewing them for exposure of sensitive data
Rotate any credentials, tokens, or session identifiers that may have been recorded in accessible log files

Patch Information

The vulnerability affects SearchIQ from an unspecified earlier version through 4.5. Refer to the Patchstack Vulnerability Report for the current patch status and vendor guidance. If a fixed version is not yet available, apply the workarounds below.

Workarounds

Deny direct web access to the SearchIQ plugin directory using web server rules that block requests to .log files under /wp-content/plugins/searchiq/
Place the WordPress installation behind a web application firewall and add a rule to block requests targeting plugin log files
Disable the SearchIQ plugin until a patched version is installed if logging cannot be restricted

bash

# Apache .htaccess rule to deny access to SearchIQ log files
<FilesMatch "\.(log|txt)$">
    Require all denied
</FilesMatch>
