Cisco Systems this week issued an update for its Adaptive Security Appliance (ASA) software, fixing a high-severity vulnerability that could allow authenticated attackers with low-level access to remotely escalate their privileges on Cisco devices with web management access enabled.

Designated CVE-2018-15465, the flaw is the result of an improper validation process while using the web management interface.

"An attacker could exploit this vulnerability by sending specific HTTP requests via HTTPS to an affected device as an unprivileged user," states a Dec. 19 Cisco security advisory. "An exploit could allow the attacker to retrieve files (including the running configuration) from the device or to upload and replace software images on the device."
