TITLE

Pillow Buffer error vulnerability

Trust: 0.6

sources: CNNVD: CNNVD-202104-975

DESCRIPTION

Multiple vulnerabilities in the web-based management interface of Cisco Business Process Automation (BPA) could allow an authenticated, remote attacker to elevate privileges to Administrator. These vulnerabilities are due to improper authorization enforcement for specific features and for access to log files that contain confidential information. An attacker could exploit these vulnerabilities either by submitting crafted HTTP messages to an affected system and performing unauthorized actions with the privileges of an administrator, or by retrieving sensitive data from the logs and using it to impersonate a legitimate privileged user. A successful exploit could allow the attacker to elevate privileges to Administrator. Pillow is a Python-based image processing library. There is currently no information about this vulnerability, please feel free to follow CNNVD or manufacturer announcements
