tag_summary = "webERP is prone to information-disclosure, SQL-injection, and cross-
site scripting vulnerabilities because it fails to sufficiently
sanitize user-supplied input.

An attacker may exploit the information-disclosure issue to gain
access to sensitive information that may lead to further attacks.

An attacker may exploit the SQL-injection issue to compromise the
application, access or modify data, or exploit latent vulnerabilities
in the underlying database.

An attacker may leverage the cross-site scripting issue to execute
arbitrary script code in the browser of an unsuspecting user in the
context of the affected site. This may allow the attacker to steal cookie-
based authentication credentials and launch other attacks.

webERP 4.0.5 is vulnerable; prior versions may also be affected.";

Hi @keven,

thanks for spotting that! This VT either needs a response check or - even better - a detection VT beforehand, so this one only runs after the application has been confirmed.

Either way, we will tackle this issue.

Thanks again!
Cheers
