Netweaver Enterprise Portal Cross-site Scripting

SAP NetWeaver Enterprise Portal (KMC) - version 7.50, does not sufficiently encode user-controlled inputs, resulting in Cross-Site Scripting vulnerability. KMC servlet is vulnerable to XSS attack. The execution of script content by a victim registered on the portal could compromise the confidentiality and integrity of victim’s web browser session. (2022-09-13, CVE-2022-35298)

A vulnerability in SAP NW EP (WPC) - versions 7.30, 7.31, 7.40, 7.50, which does not sufficiently validate user-controlled input, allows a remote attacker to conduct a Cross-Site (XSS) scripting attack. A successful exploit could allow the attacker to execute arbitrary script code which could lead to stealing or modifying of authentication information of the user, such as data relating to his or her current session. (2022-07-12, CVE-2022-35227)

SAP NetWeaver Enterprise Portal - versions 7.10, 7.11, 7.20, 7.30, 7.31, 7.40, 7.50, does not sufficiently encode user-controlled inputs over the network, resulting in reflected Cross-Site Scripting (XSS) vulnerability, therefore changing the scope of the attack. This leads to limited impact on confidentiality and integrity of data. (2022-07-12, CVE-2022-35225)

SAP NetWeaver Enterprise Portal - versions 7.10, 7.11, 7.20, 7.30, 7.31, 7.40, 7.50, does not sufficiently encode user-controlled inputs, resulting in reflected Cross-Site Scripting (XSS) vulnerability. (2022-07-12, CVE-2022-35172)

SAP NetWeaver Enterprise Portal - versions 7.10, 7.11, 7.20, 7.30, 7.31, 7.40, 7.50, is susceptible to script execution attack by an unauthenticated attacker due to improper sanitization of the User inputs while interacting on the Network. On successful exploitation, an attacker can view or modify information causing a limited impact on confidentiality and integrity of the application. (2022-07-12, CVE-2022-32247)

SAP NetWeaver Enterprise Portal does - versions 7.10, 7.11, 7.20, 7.30, 7.31, 7.40, 7.50, not sufficiently encode user-controlled inputs over the network, resulting in reflected Cross-Site Scripting (XSS) vulnerability, therefore changing the scope of the attack. This leads to limited impact on confidentiality and integrity of data. (2022-07-12, CVE-2022-35170)

SAP NetWeaver Enterprise Portal - versions 7.10, 7.11, 7.20, 7.30, 7.31, 7.40, 7.50, is susceptible to script execution attack by an unauthenticated attacker due to improper sanitization of the user inputs while interacting on the Network. On successful exploitation, an attacker can view or modify information causing a limited impact on confidentiality and integrity of the application. (2022-04-12, CVE-2022-26105)

SAP NetWeaver Enterprise Portal - versions 7.10, 7.11, 7.20, 7.30, 7.31, 7.40, 7.50, does not sufficiently encode user-controlled inputs, resulting in reflected Cross-Site Scripting (XSS) vulnerability. (2022-03-10, CVE-2022-24395)

SAP NetWeaver Enterprise Portal - versions 7.30, 7.31, 7.40, 7.50, does not sufficiently encode user-controlled inputs, resulting in reflected Cross-Site Scripting (XSS) vulnerability.This reflected cross-site scripting attack can be used to non-permanently deface or modify displayed content of portal Website. The execution of the script content by a victim registered on the portal could compromise the confidentiality and integrity of victim’s web browser. (2022-03-10, CVE-2022-24397)

SAP NetWeaver Enterprise Portal versions - 7.10, 7.11, 7.20, 7.30, 7.31, 7.40, 7.50, does not sufficiently encode user related data, resulting in Stored Cross-Site Scripting (XSS) vulnerability. This would allow an attacker with administrative privileges to store a malicious script on the portal. The execution of the script content by a victim registered on the portal could compromise the confidentiality and integrity of portal content. (2021-09-14, CVE-2021-21489)

Under certain conditions, NetWeaver Enterprise Portal, versions - 7.10, 7.11, 7.20, 7.30, 7.31, 7.40, 7.50, does not sufficiently encode report data. An attacker can craft malicious data and print it to the report. In a successful attack, a victim opens the report, and the malicious script gets executed in the victim's browser, resulting in a Stored Cross-Site Scripting (XSS) vulnerability. (2021-08-10, CVE-2021-33702)

Under certain conditions, NetWeaver Enterprise Portal, versions - 7.30, 7.31, 7.40, 7.50, does not sufficiently encode URL parameters. An attacker can craft a malicious link and send it to a victim. A successful attack results in Reflected Cross-Site Scripting (XSS) vulnerability. (2021-08-10, CVE-2021-33703)

SAP NetWeaver Enterprise Portal (Fiori Framework Page) versions - 7.50, 7.31, 7.40, does not sufficiently encode user-controlled inputs and allows an attacker on a valid session to create an XSS that will be both reflected immediately and also be persisted and returned in further access to the system, resulting in Cross Site Scripting. (2020-10-15, CVE-2020-6323)

SAP NetWeaver Enterprise Portal from 7.0 to 7.02, 7.11, 7.20, 7.30, 7.31, 7.40, 7.50, does not sufficiently encode user controlled inputs, resulting in Cross-Site Scripting (XSS) vulnerability. (2018-07-10, CVE-2018-2435)

Cross site scripting is an attack where a web page executes code that is injected by an adversary. It usually appears, when users input is presented. This attack can be used to impersonate a user, take over control of the session, or even steal API keys.

The attack can be executed e.g. when you application injects the request parameter directly into the HTML code of the page returned to the user:

https://server.com/confirmation?message=Transaction+Complete

what results in:

<span>Confirmation: Transaction Complete</span>

In that case the message can be modified to become a valid Javascript code, e.g.:

https://server.com/confirmation?message=<script>dangerous javascript code here</script>

and it will be executed locally by the user's browser with full access to the user's personal application/browser data:

<span>Confirmation: <script>dangerous javascript code here</script></span>
