Description
A Server-Side Template Injection (SSTI) vulnerability was identified
in the mail template functionality of the Axway SecureTransport product in version 5.5-20260326. This
flaw
allows an attacker with admin privileges to inject arbitrary Java code expressions, which are
executed server-side when the template is rendered (i.e., during email
sending). Successful exploitation of this flaw allows an attacker to
execute
arbitrary code on the server that results in full host compromise.
This issue affects all Axway SecureTransport versions prior 5.5-20260528 update.
