Description

A local privilege escalation vulnerability in HPE Networking Fabric Composer could allow an authenticated privileged user on the underlying host to elevate their user privileges to those of a higher role. A successful exploit allows the attacker to change the state of certain settings of the affected system.

  "executiveSummary": "A local privilege escalation vulnerability exists within HPE Networking Fabric Composer, potentially allowing an already authenticated privileged user to bypass existing access controls.\nThe vulnerability resides in the management of system settings, where improper authorization checks or process handling enables a user to elevate their effective permissions to a higher-privileged role.\nThis flaw impacts the integrity and availability of the affected system, as successful exploitation grants the attacker the ability to modify critical configurations, potentially leading to unauthorized system state changes.\nExploitation of this vulnerability requires the attacker to already possess authenticated, privileged access to the underlying host, limiting the attack surface to malicious insiders or compromised administrative accounts.\nNo network-based exploitation is indicated; the attack is strictly local in nature, necessitating existing host access. Organizations should prioritize restricted access management and monitoring of privileged sessions to mitigate the risk of unauthorized role escalation.",
  "technicalDetails": "The vulnerability manifests as an authorization flaw within the HPE Networking Fabric Composer architecture, specifically affecting the interface or service responsible for modifying system-level configurations.\nWhile the specific root cause involves improper validation of user roles during the execution of privileged administrative commands, the underlying mechanism permits an authenticated user with restricted privileged access to bypass standard access control lists (ACLs) or role-based access control (RBAC) mechanisms.\nThe attack flow begins with an authenticated user initiating a request to the system's management interface or background service tasked with handling configuration states. By manipulating the parameters of these requests or leveraging an insecure inter-process communication (IPC) channel, the attacker triggers an action that the system fails to associate with the user's actual restricted role.\nBecause the service responsible for executing these changes does not adequately verify the authorization context of the calling process or user, it proceeds to perform the operation with elevated system privileges.\nThe payload behavior involves the modification of restricted system settings that are otherwise protected from the standard authenticated user. This post-exploitation capability allows for the alteration of system states, which may include disabling security features, modifying network policies, or reconfiguring the fabric environment to suit the attacker's objectives.\nThe vulnerability does not require external network exposure, as the attack vector is confined to the local host environment. The primary requirement for an adversary is the ability to authenticate to the underlying host as a privileged user, though the vulnerability fundamentally breaks the segregation between those privileged tiers, facilitating a vertical escalation of privileges.\nTechnical exploitation effectively exploits a logic error in the privilege verification function, allowing the attacker to execute administrative commands that should be reserved for the highest tier of system management roles."
