CVE-2025-24594: Linet ERP-WooCommerce Auth Bypass Flaw

CVE-2025-24594 Overview

CVE-2025-24594 is a Missing Authorization vulnerability [CWE-862] affecting the Linet ERP-Woocommerce Integration plugin for WordPress by aribhour. The flaw stems from incorrectly configured access control security levels, allowing unauthenticated network attackers to invoke plugin functionality that should be restricted. Affected versions include all releases from n/a through <= 3.5.7. The vulnerability is exploitable over the network without user interaction or privileges, and it can result in limited integrity and availability impact on affected WooCommerce sites.

Critical Impact
Unauthenticated attackers can reach protected plugin functionality due to broken access control, and the issue can be paired with Cross-Site Request Forgery (CSRF) to abuse authenticated site administrators.

Affected Products

aribhour Linet ERP-Woocommerce Integration plugin for WordPress
All versions from initial release through 3.5.7
WordPress sites running WooCommerce with the affected plugin installed

Technical Details for CVE-2025-24594

Vulnerability Analysis

The Linet ERP-Woocommerce Integration plugin exposes plugin endpoints without enforcing proper authorization checks. Missing Authorization [CWE-862] means the application performs sensitive actions without verifying whether the caller has permission. According to the Patchstack advisory, the flaw combines broken access control with a CSRF vector, enabling attackers to trigger plugin functionality by luring an authenticated administrator to a malicious page. The affected functionality operates over the network and requires no privileges or user interaction from the attacker's side.

Root Cause

The plugin fails to implement WordPress capability checks such as current_user_can() and nonce validation via wp_verify_nonce() on sensitive request handlers. Without these checks, request handlers accept input from unauthorized sources and act on it as if the caller were a legitimate privileged user. This mirrors the standard Missing Authorization pattern documented in CWE-862.

Attack Vector

Attackers reach the affected endpoints across the network. Exploitation does not require credentials on the target WordPress site. When chained with CSRF, an attacker crafts a page or link that, when visited by a signed-in administrator, silently issues requests to the plugin's endpoints. The result is limited unauthorized modification of plugin state and disruption of integration functionality between WooCommerce and Linet ERP.

No public proof-of-concept exploit is listed for this issue. Refer to the Patchstack Vulnerability Report for the vendor-neutral technical details.

Detection Methods for CVE-2025-24594

Indicators of Compromise

Unexpected WooCommerce order, product, or customer synchronization events written by the Linet integration outside normal business workflows.
HTTP POST requests to plugin endpoints under /wp-admin/admin-ajax.php or /wp-json/ paths tied to linet-erp-woocommerce-integration originating from external referrers.
WordPress audit log entries showing administrator-scoped actions immediately after the administrator browsed an untrusted external site.

Detection Strategies

Inventory WordPress installations and flag any site running Linet ERP-Woocommerce Integration at version 3.5.7 or earlier.
Inspect web server access logs for unauthenticated requests to plugin action handlers and correlate with a lack of valid _wpnonce parameters.
Enable a WordPress activity logging plugin to record administrative changes triggered by the integration and alert on anomalous frequency or off-hours execution.

Monitoring Recommendations

Forward WordPress and web server logs to a centralized log platform and build detections for requests to the plugin's endpoints without valid session or nonce values.
Monitor outbound traffic from the WordPress host to the Linet ERP API for unexpected payloads that could indicate abuse of the integration.
Track file integrity on the wp-content/plugins/linet-erp-woocommerce-integration/ directory to detect tampering.

How to Mitigate CVE-2025-24594

Immediate Actions Required

Update the Linet ERP-Woocommerce Integration plugin to a version later than 3.5.7 once the vendor publishes a fix.
If no fixed version is available, deactivate and remove the plugin until a patched release is confirmed.
Enforce least privilege on WordPress accounts and require administrators to authenticate from managed browsers to reduce CSRF exposure.

Patch Information

As of publication, the Patchstack advisory tracks the vulnerability against versions up to and including 3.5.7. Site owners should monitor the plugin listing on WordPress.org and the vendor advisory for a patched release, then apply the update promptly.

Workarounds

Restrict access to /wp-admin/ and plugin AJAX/REST endpoints using a web application firewall rule that requires valid session cookies and nonce parameters.
Apply IP allowlisting for administrative sessions so that CSRF-driven requests from untrusted networks are blocked at the perimeter.
Require administrators to use a dedicated browser profile for WordPress management to limit exposure to CSRF payloads embedded in third-party sites.
