CVSS v3.1

Official Description

Multiple cross-site scripting (XSS) vulnerabilities in McAfee ePolicy Orchestrator 4.6.6 and earlier, and the ePO Extension for the McAfee Agent (MA) 4.5 through 4.6, allow remote attackers to inject arbitrary web script or HTML via the (1) instanceId parameter core/loadDisplayType.do; (2) instanceId or (3) monitorUrl parameter to console/createDashboardContainer.do; uid parameter to (4) ComputerMgmt/sysDetPanelBoolPie.do or (5) ComputerMgmt/sysDetPanelSummary.do; (6) uid, (7) orion.user.security.token, or (8) ajaxMode parameter to ComputerMgmt/sysDetPanelQry.do; or (9) uid, (10) orion.user.security.token, or (11) ajaxMode parameter to ComputerMgmt/sysDetPanelSummary.do.

Technical Analysis

CVE-2013-4883 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A proof-of-concept (PoC) exploit exists for CVE-2013-4883. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.

From a weakness classification perspective (CWE-79): Cross-site scripting (XSS) vulnerabilities allow attackers to inject malicious scripts into web pages viewed by other users.
