Vulnerability from variot

Stack-based buffer overflow in the Profinet DCP protocol implementation on the Siemens Scalance S Security Module firewall S602 V2, S612 V2, and S613 V2 with firmware before 2.3.0.3 allows remote attackers to cause a denial of service (device outage) or possibly execute arbitrary code via a crafted DCP frame. The Siemens SCALANCE S-series security modules can be used to protect all Ethernet devices from unauthorized access. The WEB configuration interface provided by the Siemens SCALANCE firewall does not impose a mandatory time delay on the failed login, allowing the attacker to detect a large number of passwords in a short period of time and perform brute force attacks. The following devices are affected by this vulnerability: * Scalance S602 V2 Scalance S612 V2 Scalance S613 V2. The Profinet DCP protocol handles errors that can make the firewall unresponsive or interrupt an established VPN tunnel through a specially crafted DCP frame. Siemens Scalance Firewall filters inbound and outbound network connections in a variety of ways to secure a trusted industrial network. Siemens Scalance Firewall has multiple vulnerabilities in its implementation that can be exploited by malicious users to perform brute force attacks or cause denial of service. Siemens Scalance Firewall is prone to a denial-of-service vulnerability and a security-bypass weakness. Attackers can exploit these issues to cause denial-of-service conditions or conduct brute-force attacks. Profinet DCP There was an error in the protocol processing. ----------------------------------------------------------------------

    "data": "Stack-based buffer overflow in the Profinet DCP protocol implementation on the Siemens Scalance S Security Module firewall S602 V2, S612 V2, and S613 V2 with firmware before 2.3.0.3 allows remote attackers to cause a denial of service (device outage) or possibly execute arbitrary code via a crafted DCP frame. The Siemens SCALANCE S-series security modules can be used to protect all Ethernet devices from unauthorized access. The WEB configuration interface provided by the Siemens SCALANCE firewall does not impose a mandatory time delay on the failed login, allowing the attacker to detect a large number of passwords in a short period of time and perform brute force attacks. The following devices are affected by this vulnerability: * Scalance S602 V2* Scalance S612 V2* Scalance S613 V2. The Profinet DCP protocol handles errors that can make the firewall unresponsive or interrupt an established VPN tunnel through a specially crafted DCP frame. Siemens Scalance Firewall filters inbound and outbound network connections in a variety of ways to secure a trusted industrial network. Siemens Scalance Firewall has multiple vulnerabilities in its implementation that can be exploited by malicious users to perform brute force attacks or cause denial of service. Siemens Scalance Firewall is prone to a denial-of-service vulnerability and a security-bypass weakness. \nAttackers can exploit these issues to cause denial-of-service conditions or conduct brute-force attacks.
