VAR-201503-0332
Vulnerability from variot - Updated: 2023-12-18 12:45Stack-based buffer overflow in the PmBase64Decode function in an unspecified demonstration application in MICROSYS PROMOTIC stable before 8.2.19 and PROMOTIC development before 8.3.2 allows remote attackers to execute arbitrary code by providing a large amount of data. Authentication is not required to exploit this vulnerability.The program blindly copies attacker-supplied data into a fixed-sized buffer without validating the length of this data resulting in a stack buffer overflow. The specific flaw exists within the PmBase64Decode function which ignores the passed-in length of the destination buffer. An attacker can exploit this condition to achieve code execution under the context of the process. MICROSYS PROMOTIC is a SCADA software. Failed exploit attempts will result in a denial-of-service condition
