Technical details

The vulnerability is a broken access control flaw in the CPB Log Files feature of WaveSuite. An authenticated low-privilege user can bypass role-based access controls by directly requesting URLs that should be restricted to higher-privilege roles, without additional authentication or checks. The vulnerability allows an attacker to enumerate and access log files and administrative pages not intended for their privilege level. This is a horizontal privilege escalation triggered purely by URL manipulation, requiring only valid (low-level) authentication and network access to the WaveSuite interface. Patch availability was not confirmed from the provided sources.
