Sophos addressed a vulnerability in its Cyberoam firewalls that could be exploited by an attacker to gain access to a company’s internal network without providing a password.
“A critical shell injection vulnerability in Sophos Cyberoam Firewall appliances running CyberoamOS (CROS) version 10.6.6 MR-5 and earlier was recently discovered and responsibly disclosed to Sophos by an external security researcher.” reads the advisory published by Sophos.
“The vulnerability can be potentially exploited by sending a malicious request to either the Web Admin or SSL VPN consoles, which would enable an
The vulnerability is a critical shell injection vulnerability that could allow a remote attacker to gain “root” permissions on vulnerable equipment, it could be exploited by sending malicious commands across the internet.
