VAR-200307-0036
Vulnerability from variot - Updated: 2025-04-03 22:39Privacyware Privatefirewall 3.0 does not block certain incoming packets when in "Filter Internet Traffic" or Deny Internet Traffic" modes, which allows remote attackers to identify running services via FIN scans or Xmas scans. It has been reported that Privatefirewall does not properly handle TCP traffic with certain flag settings. This may allow an attacker to circumvent firewall filtering. Privatefirewall is a set of firewall software that integrates personal firewall and intrusion detection system. Privatefirewall does not properly handle the communication of some specially marked packets. Remote attackers can exploit this vulnerability to bypass filtering restrictions and access protected resources. The filtering rules of Privatefirewall cannot detect FIN and /Xmas scans, and attackers can use scanning tools such as NMAP to scan protected resources and obtain sensitive information
