IBM WebSphere eXtreme Scale 8.6.1.0 < 8.6.2.2 XSS (7293764)

medium Nessus Plugin ID 379783

Synopsis

The remote web application server is affected by multiple vulnerabilities

Description

The version of IBM WebSphere eXtreme Scale installed on the remote host is prior to 8.6.2.2 IBM. It is, therefore, affected by multiple vulnerabilities as referenced in the 7293764 advisory.

 - In jQuery versions greater than or equal to 1.0.3 and before 3.5.0, passing HTML containing <option> elements from untrusted sources - even after sanitizing it - to one of jQuery's DOM manipulation methods (i.e. .html(), .append(), and others) may execute untrusted code. This problem is patched in jQuery 3.5.0.
 (CVE-2020-11023)

 - IBM WebSphere Extreme Scale 8.6.1.0 through 8.6.2.2 could allow a remote attacker to bypass security restrictions due to improper Content Security Policy configuration. (CVE-2026-101117)

 - Node.js C3.js c3 module is vulnerable to cross-site scripting, caused by improper validation of user- supplied input by the tooltip. A remote attacker could exploit this vulnerability to inject malicious script into a Web page which would be executed in a victim's Web browser within the security context of the hosting Web site, once the page is viewed. An attacker could use this vulnerability to steal the victim's cookie-based authentication credentials. CWE: CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') (CVE-2016-1000240)

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