UI spoofing via path-relative stylesheet import
Published Jul 22, 2021 · Updated Aug 3, 2024
Path-relative stylesheet import in the AOS-CX web interface allows attackers to alter displayed pages through crafted CSS references. Relative HTML URLs fail to anchor stylesheet paths to the intended directory, allowing attacker-supplied references to replace expected styles. HPE describes unauthenticated exploitation, while its published assessment requires local low-privilege access, leaving the precise access gate internally inconsistent.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
