medium Nessus Plugin ID 140504

Synopsis

The remote SAP NetWeaver AS Java server may be affected by cross-site scripting vulnerabilities

Description

The version of SAP NetWeaver AS Java detected on the remote host may be affected by multiple cross-site scripting vulnerabilities, as follows:

- SAP NetWeaver Application Server JAVA (XML Forms) versions 7.30, 7.31, 7.40, 7.50 does not sufficiently encode user controlled inputs, which allows an authenticated User with special roles to store malicious content, that when accessed by a victim, can perform malicious actions by executing JavaScript, leading to Stored Cross-Site Scripting. (CVE-2020-6313)

- SAP NetWeaver (Knowledge Management), version-7.30,7.31,7.40,7.50, allows an authenticated attacker to create malicious links in the UI, when clicked by victim, will execute arbitrary java scripts thus extracting or modifying information otherwise restricted leading to Stored Cross Site Scripting. (CVE-2020-6326)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Apply the appropriate patch according to the vendor advisory.
