An information-disclosure vulnerability 3. A file-upload vulnerability 4. Multiple directory-traversal vulnerabilities 5. Multiple stack-based buffer-overflow vulnerabilities 6. A heap-based buffer-overflow vulnerability 7. Multiple arbitrary code-execution vulnerabilities 8. A denial-of-service vulnerability 9. A security-bypass vulnerability 10. A privilege-escalation 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, delete arbitrary files, gain elevated privileges, perform certain unauthorized actions, upload arbitrary files to the affected application gain unauthorized access and obtain sensitive information. Failed attacks will cause denial of service conditions. Advantech WebAccess, etc. The following versions are affected: Advantech WebAccess 8.2_20170817 and earlier, 8.3.0 and earlier; WebAccess Dashboard 2.0.15 and earlier; WebAccess Scada Node 8.3.1 and earlier; WebAccess/NMS 2.0.3 and earlier
