CVE-2026-47096: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in AJA Video Systems HELO Plus
AJA HELO Plus firmware before 2.1.7 contains a stored cross-site scripting vulnerability that allows unauthenticated attackers with network access to inject malicious JavaScript by setting an unsanitized eParamID_SystemName value through the /config?action=set web configuration API. Attackers can exploit this flaw when device authentication is disabled to persistently execute arbitrary script in the browser of any administrator who opens the web management interface, enabling theft of stored secrets such as web UI credentials, RTMP stream keys, publish URLs, and NFS/SMB share credentials, as well as hijacking of the authenticated session.
AI Analysis
Technical Summary
CVE-2026-47096 is a stored cross-site scripting vulnerability in AJA Video Systems HELO Plus firmware versions prior to 2.1.7. The vulnerability arises from improper neutralization of input during web page generation, specifically through the unsanitized eParamID_SystemName parameter in the /config?action=set web configuration API. An unauthenticated attacker with network access can inject malicious JavaScript if device authentication is disabled. When an administrator later accesses the web management interface, the injected script executes persistently, potentially stealing stored secrets and hijacking the authenticated session.
Potential Impact
Successful exploitation can lead to theft of stored sensitive information including web UI credentials, RTMP stream keys, publish URLs, and NFS/SMB share credentials. Additionally, attackers can hijack authenticated sessions of administrators accessing the web interface. This compromises device management and streaming security.
Mitigation Recommendations
A fix is available in firmware version 2.1.7. Users should upgrade to version 2.1.7 or later to remediate this vulnerability. Until upgraded, ensure that device authentication is enabled to prevent unauthenticated attackers from exploiting this issue.
