Cisco Unified Communications Manager (CUCM), Cisco Unified Contact Center Express (aka Unified CCX or UCCX), and Cisco Unified IP Interactive Voice Response (Unified IP-IVR) are all communication solutions offered by Cisco for businesses. These systems allow for flexible and efficient communication between employees, customers, and clients. CUCM, in particular, is used for call routing, collaboration, and video communications, while UCCX is primarily used for customer service and contact routing. Unified IP-IVR is commonly used for automated telephone menus and self-service applications.
CVE-2011-3315 is a vulnerability detected in these Cisco communication solutions. This directory traversal vulnerability allows remote attackers to read arbitrary files as a result of a crafted URL. This specific vulnerability was found in CUCM 5.x and 6.x before 6.1(5)SU2, 7.x before 7.1(5b)SU2, and 8.x before 8.0(3), as well as Unified CCX and Unified IP-IVR before 6.0(1)SR1ES8, 7.0(x) before 7.0(2)ES1, 8.0(x) through 8.0(2)SU3, and 8.5(x) before 8.5(1)SU2.
