TITLE

plural SINUMERIK Vulnerabilities related to authorization, authority, and access control in products

Trust: 0.8

sources: JVNDB: JVNDB-2018-013317

DESCRIPTION

A vulnerability has been identified in SINUMERIK 808D V4.7 (All versions), SINUMERIK 808D V4.8 (All versions), 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). By sending a specially crafted authentication request to the affected systems a remote attacker could escalate his privileges to an elevated user account but not to root. The security vulnerability could be exploited by an attacker with network access to the affected systems. Successful exploitation requires no privileges and no user interaction. The vulnerability could allow an attacker to compromise confidentiality, integrity and availability of the system. At the time of advisory publication no public exploitation of this security vulnerability was known. SINUMERIK 808D , SINUMERIK 828D , SINUMERIK 840D sl 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. Permission access control vulnerabilities exist in several Siemens products. Siemens SINUMERIK Controllers is prone to the following security vulnerabilities: 1. A heap based buffer-overflow vulnerability. 2. An integer overflow vulnerability. 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
