Vulnerability from variot
An Incorrect Privilege Assignment issue was discovered in Advantech WebAccess versions prior to V8.2_20170817. A built-in user account has been granted a sensitive privilege that may allow a user to elevate to administrative privileges. Advantech WebAccess 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. Advantech WebAccess is a suite of browser-based HMI/SCADA software from Advantech. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. Advantech WebAccess is prone to the following security vulnerabilities: 1. Multiple stack-based buffer-overflow vulnerabilities 2. Multiple heap-based buffer-overflow vulnerabilities. 3. Multiple memory-corruption vulnerabilities. 4. An SQL-injection vulnerability. 5. A format-string vulnerability. 6. An authentication-bypass vulnerability. 7. A security-bypass vulnerability. 8. A privilege-escalation vulnerability. 9. A remote-code execution vulnerability. An attacker can exploit these issues to execute arbitrary code in the context of the application, or modify data, or exploit latent vulnerabilities in the underlying database,perform certain unauthorized actions, gain unauthorized access and gain elevated privileges. This may aid in further attacks. Advantech WebAccess versions prior to V8.2_20170817 are vulnerable. There is a security vulnerability in Advantech WebAccess 8.2_20170817 and earlier versions, the vulnerability is caused by the program not having the correct assigned permissions
