TITLE

SINUMERIK 828D and SINUMERIK 840D Vulnerabilities related to authorization, permissions, and access control

Trust: 0.8

sources: JVNDB: JVNDB-2018-013322

DESCRIPTION

A vulnerability has been identified in SINUMERIK 828D V4.7 (All versions < V4.7 SP6 HF1), SINUMERIK 840D sl V4.7 (All versions < V4.7 SP6 HF5), SINUMERIK 840D sl V4.8 (All versions < V4.8 SP3). The integrated VNC server on port 5900/tcp of the affected products could allow a remote attacker to execute code with privileged permissions on the system by sending specially crafted network requests to port 5900/tcp. Please note that this vulnerability is only exploitable if port 5900/tcp is manually opened in the firewall configuration of network port X130. The security vulnerability could be exploited by an attacker with network access to the affected devices and port. Successful exploitation requires no privileges and no user interaction. The vulnerability could allow an attacker to compromise confidentiality, integrity and availability of the VNC server. At the time of advisory publication no public exploitation of this security vulnerability was known. SINUMERIK 828D and SINUMERIK 840D Contains vulnerabilities related to authorization, permissions, and access control.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. The Siemens SINUMERIK 808D is a CNC machine system controller from Siemens AG. An integer overflow vulnerability exists in the Siemens SINUMERIK CNC Controller. Siemens SINUMERIK Controllers is prone to the following security vulnerabilities: 1. A heap based buffer-overflow vulnerability. 2. 3. A security bypass vulnerability. 4. An arbitrary code execution vulnerability. 5. Multiple privilege escalation vulnerabilities. 6. A stack based buffer-overflow vulnerability. 7. A buffer-overflow vulnerability. 8. Multiple denial-of-service vulnerabilities Attackers can exploit these issues to execute arbitrary code within the context of affected device, gain host privileges and perform unauthorized actions, to modify or destroy data without having proper authorization to do so, to bypass security restrictions or cause a denial-of-service condition. Siemens SINUMERIK 808D, etc
