Cisco SPA500 Firmware

A vulnerability in Cisco SPA300 and SPA500 Series IP Phones could allow an unauthenticated, remote attacker to execute unwanted actions on an affected device. The vulnerability is due to a lack of cross-site request forgery (CSRF) protection. An attacker could exploit this vulnerability by tricking the user of a web application into executing an adverse action. Cisco Bug IDs: CSCuz88421, CSCuz91356, CSCve56308.

The HTTP framework on Cisco SPA300, SPA500, and SPA51x devices allows remote attackers to cause a denial of service (device outage) via a series of malformed HTTP requests, aka Bug ID CSCut67385.

Cisco SPA112, SPA525, and SPA5x5 Series IP Phones Certificate Validation Vulnerability

The TFTP implementation on Cisco Small Business SPA30x, SPA50x, SPA51x phones 7.5.7 improperly validates firmware-image file integrity, which allows local users to load a Trojan horse image by leveraging shell access, aka Bug ID CSCut67400.

The default configuration of Cisco Small Business IP phones SPA 300 7.5.5 and SPA 500 7.5.5 does not properly support authentication, which allows remote attackers to read audio-stream data or originate telephone calls via a crafted XML request, aka Bug ID CSCuo52482.
