VAR-201308-0077
Vulnerability from variot - Updated: 2025-04-11 22:55Buffer overflow in Artweaver before 3.1.6 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted AWD file. Zavio IP Cameras are webcam products. In the Boa web server used by Zavio IP Cameras, there is an account in the configuration file 'boa.conf' which cannot be seen from the user web interface, but can access two files in '/cgi-bin/mft/' through this account. ('manufacture.cgi', 'wireless_mft.cgi'), one of the files has an OS command injection vulnerability. Can lead to illegal access to affected products. Artweaver is prone to a remote buffer-overflow vulnerability because it fails to properly bounds-check user-supplied input before copying it to an insufficiently sized memory buffer. Attackers may leverage this issue to execute arbitrary code in the context of the application. Failed exploit attempts may result in a denial-of-service condition. Artweaver 3.1.5 is vulnerable; other versions may also be affected. Core Security - Corelabs Advisory http://corelabs.coresecurity.com/
