Advisory
SAP takes the security of its vast product portfolio very seriously and thus releases security fixes for
vulnerabilities reported by external researchers and their customers every second Tuesday of the month.
SAP Note 2606194
was released on
09.09.2020 and deals with
"Cross-Site Scripting (XSS) vulnerability in CRM Interaction Center" within ABAP.
We advice you to follow the instructions, to resolve
Cross-Site Scripting (XSS)
with a
medium potential for exploitation
in component CRM-IC-FRW.
According to SAP Security Advisory team a workaround does not exist. It is advisable to implement the correction as monthly patch process.
Missing authority checks are still the most common security defect related to authorizations in custom code.
Since SAP uses an explicit authorization model, an authority checks must be coded in order to be executed. If an
explicit check is not coded, all users have access.
This type of vulnerability not only exists in SAP standard it also exists in customer coding. Check your custom
developments for vulnerabilities that pose a risk to your systems. SecurityBridge helps
detect code
vulnerabilities before they are implemented in production.
Cross-site scripting (XSS) is the name of a class of security vulnerabilities that can occur in web-based
applications. XSS combines
all vulnerabilities that allow an attacker to inject HTML Markup and/or JavaScript into the front end of the
affected web application.
XSS attacks can occur whenever the application dynamically creates its HTML/JavaScript/CSS content, which is passed
to the
user's web browser, and attacker-controlled values are used in this process. If these values are included in the
generated code without proper validation and encoding, the attacker is able to include arbitrary
coding snippets into the application's front end. The code is then rendered by the victim's web browser and
interpreted in the victim's current authentication context.
Risk specification
The WebUI in SAP CRM Interaction Center is the central interface for internal agents to process and document customer requests. User inputs are not sufficiently encoded, which leaves the option for authenticated attackers to exploit a Cross-Site Scripting (XSS) vulnerability.Solution
Company name / contact name in context area are now properly encoded to prevent a XSS attach.
