LTL Freight Quotes Old Dominion Edition: Unauthenticated SQL injection
Summary
The LTL Freight Quotes – Old Dominion Edition WordPress plugin does not sanitise and escape the 'edit_id' parameter of the shipping rule before using it in an SQL statement. An unauthenticated attacker can send crafted requests to inject SQL commands into the database, which could expose stored data such as customer or order information. The CVSS vector indicates high confidentiality impact without integrity or availability impact; no public exploit has been confirmed.
Affected
- LTL Freight Quotes – Old Dominion Edition from 4.2.11 up to and including 4.2.18
- Whether versions before 4.2.11 are affected is unknown.
Fixed in
- Version 4.2.19 or later
Workaround
- No vendor-published workaround known.
- If patching must wait: deactivate the plugin if live freight quotes are not needed, or restrict the affected endpoints with a web application firewall (general measure, not vendor-tested).
Exploitation
- CISA SSVC: exploitation none, automatable yes, technical impact partial.
- Not listed in CISA KEV.
- EPSS 0.00177 (low predicted exploitation probability).
- No public proof of concept confirmed.
Our recommendation
- Identify all WordPress sites using the LTL Freight Quotes plugin, including all editions, and record their versions.
- Update to version 4.2.19 or later and verify the installed version.
- If patching is not possible immediately, deactivate the plugin or restrict exposure at the WAF.
- Review web server and database logs for unusual requests to shipping rule and quote endpoints, and check for data exposure.
- Recheck the WPScan entry and NVD once analysis is complete.
