TITLE

Advantech WebAccess Buffer error vulnerability

Trust: 1.4

sources: JVNDB: JVNDB-2017-007399 // CNNVD: CNNVD-201708-1280

DESCRIPTION

A heap-based buffer overflow issue was discovered in Advantech WebAccess versions prior to V8.2_20170817. Researchers have identified multiple vulnerabilities where there is a lack of proper validation of the length of user-supplied data prior to copying it to the heap-based buffer, which could allow an attacker to execute arbitrary code under the context of the process. Advantech WebAccess Contains a buffer error vulnerability.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. This may aid in further attacks. Advantech WebAccess versions prior to V8.2_20170817 are vulnerable. The vulnerability stems from the fact that the program does not fully verify the length of the data submitted by the user
