A vulnerability in Cisco Expressway Series could allow an unauthenticated, remote attacker to obtain sensitive information from an affected device. This vulnerability is due to insufficient authorization checks of HTTP requests during Mobile and Remote Access (MRA) provisioning. An attacker could exploit this vulnerability by submitting a crafted URL request to an affected device. A successful exploit could allow the attacker to access sensitive information that they would otherwise not have authorization to access. Note: Cisco Expressway Series refers to Cisco Expressway Core (Expressway-C) devices and Cisco Expressway Edge (Expressway-E) devices.
