Cisco is warning of a critical flaw in the web server of its IP phones.
Cisco issued patches in a Wednesday advisory for the flaw, which affects various versions of its Cisco IP phones for small- to medium-sized businesses.
According to Jacob Baines with Tenable, who discovered the flaw, Cisco IP phone web servers lack proper input validation for HTTP requests.
Affected products include: IP Phone 7811, 7821, 7841, and 7861 Desktop Phones; IP Phone 8811, 8841, 8845, 8851, 8861, and 8865 Desktop Phones; Unified IP Conference Phone 8831 and Wireless IP Phone 8821 and 8821-EX. Of note, according to Cisco, some of these products are utilized by the healthcare industry who are currently on the frontlines of the coronavirus pandemic.
Beyond Cisco's patches, one mitigation for the flaw is disabling web access on the IP phones, according to Cisco.
