SAP Customer Relationship Management CVE-2019-0368 Cross Site Scripting Vulnerability

Description

SAP Customer Relationship Management (CRM) is prone to a cross-site scripting vulnerability because it fails to properly sanitize user-supplied input. Remote attackers can exploit this issue to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may allow the attacker to steal cookie-based authentication credentials and launch other attacks.

Recommendations

Deploy network intrusion detection systems to monitor network traffic for malicious activity.
Deploy NIDS to monitor network traffic for signs of anomalous or suspicious activity which may indicate exploit attempts or activity that results from successful exploits.

Do not follow links provided by unknown or untrusted sources.
Web users should be cautious about following links to websites that are provided by unfamiliar or suspicious sources. Filtering HTML from emails may help remove a possible vector for transmitting malicious links to users.

Set web browser security to disable the execution of JavaScript.
Since exploiting cross-site scripting issues often requires malicious script code to run in browsers, consider disabling script code and active content support within a client browser as a way to prevent a successful exploit. Note that this mitigation tactic might adversely affect legitimate sites that rely on the execution of browser-based script code.

Run all software as a nonprivileged user with minimal access rights.
To limit the impact of latent vulnerabilities, configure servers and other applications to run as a nonadministrative user with minimal access rights.
