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 2607126
was released on
09.11.2021 and deals with
"Cross-Site Request Forgery vulnerability in Enterprise Services Repository of SAP Process Integration" within Java.
We advice you to follow the instructions, to resolve
Cross-Site Scripting (XSS)
with a
medium potential for exploitation
in component BC-XI-IBF.
According to SAP Security Advisory team a workaround does not exist. It is advisable to implement the correction as monthly patch process .
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
Enterprise Services Repository (ESR) does not sufficiently encode user-controlled inputs, resulting in Cross-Site Scripting (XSS) vulnerability which would allow an unauthenticated attacker to hijack session and non-repudiation.Solution
The respective input/output encoding has been added preventing a successful reflected XSS attack.
