CyberRota Analysis
AI-GeneratedThe Zero Spam plugin for WordPress is vulnerable to Stored Cross-Site Scripting (XSS) due to inadequate input sanitization and output escaping, allowing unauthenticated attackers to inject malicious scripts via Contact Form 7 submissions. This vulnerability can lead to the execution of arbitrary web scripts on affected pages, compromising user security. WordPress site administrators using the Zero Spam plugin should prioritize patching this issue to protect their users from potential exploits.
Original NVD Description
The Zero Spam for WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Nested POST Array Keys via Contact Form 7 Integration in all versions up to, and including, 5.7.10 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The payload is delivered by submitting a Contact Form 7 request with a nested POST array key containing arbitrary HTML or JavaScript — PHP parses the field name into a nested array key, which is stored verbatim in the zerospam_log.submission_data column when Zero Spam flags the submission as spam due to the absence of the zerospam_david_walsh_key field.
