A vulnerability in the authorization module of Cisco Content Security Management Appliance (SMA) Software and Cisco Email Security Appliance (ESA) could allow an authenticated, remote attacker to gain out-of-scope access to email. The vulnerability exists because the affected software does not correctly implement role permission controls. An attacker could exploit this vulnerability by using a custom role with specific permissions. A successful exploit could allow the attacker to access the spam quarantine of other users. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
