Reflected Cross Site Scripting in “bsp_vhelp” BSP Application
Impact on Business
By exploiting this vulnerability a remote attacker could trick users into clicking malicious links and depending on the level of protection that the browser provides, the attacker could potentially steal their user sessions or other information.
Vulnerability Details
Due to insufficient input sanitization, SAP NetWeaver AS ABAP (BSP Framework) allows an unauthenticated user to alter the current session of the user by injecting the malicious code over the network and gain access to the unintended data. This may lead to a limited impact on the confidentiality and the integrity of the application.
