AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
OSIsoft PI Vision versions 2017 and prior lack the X-XSS-Protection response header, leaving users vulnerable to reflected cross-site scripting attacks.
Vulnerability
PI Vision versions 2017 and prior do not set the X-XSS-Protection header to block, allowing reflected cross-site scripting (XSS) [1]. An attacker can inject malicious script via crafted URLs.
Exploitation
No authentication is required; the attacker sends a malicious link to a user who must click it to trigger the reflected XSS [1]. The exploit requires low skill level.
Impact
Successful exploitation leads to arbitrary script execution in the context of the victim's session, potentially exposing sensitive information or enabling remote code execution [1].
Mitigation
Upgrade to PI Vision 2017 R2 Update 1, available from OSIsoft [1]. Additional defensive measures include network isolation and VPN usage as recommended by NCCIC [1].
