Interspire Email Marketer is prone to the following input-validation vulnerabilities because it fails to properly sanitize user-supplied input:
1. An SQL injection vulnerabilities
2. Multiple HTML injection vulnerabilities
3. A cross-site scripting vulnerability
Exploiting these issues could allow an attacker to run malicious HTML and script codes, steal cookie-based authentication credentials, compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database.
Email Marketer 6.0.1 is vulnerable; other versions may be affected.
