What is CVE-2017-6636?

CVE-2017-6636 is a medium-severity path traversal vulnerability in Cisco Prime Collaboration Provisioning, published on 22 May 2017. Any signed-in user can exploit it over the network, with no action from the victim.

Official description

A vulnerability in the web interface of Cisco Prime Collaboration Provisioning Software (prior to Release 11.1) could allow an authenticated, remote attacker to view any file on an affected system. The vulnerability exists because the affected software does not perform proper input validation of HTTP requests and fails to apply role-based access controls (RBACs) to requested HTTP URLs. An attacker could exploit this vulnerability by sending a crafted HTTP request that uses directory traversal techniques to submit a path to a desired file location on an affected system. A successful exploit could allow the attacker to view any file on the system. Cisco Bug IDs: CSCvc99604.

Weakness: CWE-22
