Cisco HyperFlex Software Cross-Frame Scripting Vulnerability

Vulnerability

Cisco HyperFlex Software releases 3.5.2f and earlier, and 4.0.1b and earlier, are vulnerable to cross-frame scripting (XFS) due to insufficient HTML iframe protection in the web-based interface [1]. An attacker can embed a malicious iframe in an attacker-controlled web page.

Exploitation

An unauthenticated, remote attacker can exploit this vulnerability by directing a user to a malicious web page containing a crafted HTML iframe [1]. No authentication or special network position is required; the attacker only needs to lure the user to the page.

Impact

Successful exploitation allows the attacker to perform clickjacking or other client-side browser attacks, potentially tricking the user into performing unintended actions within the context of the HyperFlex interface [1]. The attacker does not gain direct access to the system but can manipulate user interactions.

Mitigation

Cisco has not released a specific fixed version in the advisory; no workarounds exist [1]. Customers should monitor Cisco Security Advisories for future updates and upgrade to a patched release when available.
