CVE-2023-5527: business directory vulnerability

What is known

The Business Directory Plugin plugin for WordPress is vulnerable to CSV Injection in versions up to, and including, 6.4.3 via the class-csv-exporter.php file. This allows authenticated attackers, with author-level permissions and above, to embed untrusted input into CSV files exported by administrators, which can result in code execution when these files are downloaded and opened on a local system with a vulnerable configuration.

Business impact

Successful exploitation of CVE-2023-5527, a high vulnerability (CVSS 7.4) affecting business directory, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.

Recommended administrator action

Confirm whether business directory is present and compare installed versions with the vendor advisory and NVD record. Apply the vendor patch or documented mitigation; until remediation is complete, reduce exposure of affected interfaces, review relevant logs and monitor for indicators of exploitation. DataHouse can support version verification, managed patching, network exposure reduction, log review and backup validation for dedicated, cloud and colocated environments.
